[ Upstream commit e5f1e8af9c9e151ecd665f6d2e36fb25fec3b110 ]

Upon a wakeup from S4, the restore kernel starts and initializes the FRED MSRs as needed from its perspective. It then loads a hibernation image, including the image kernel, and attempts to load image pages directly into their original page frames used before hibernation unless those frames are currently in use. Once all pages are moved to their original locations, it jumps to a "trampoline" page in the image kernel.

At this point, the image kernel takes control, but the FRED MSRs still contain values set by the restore kernel, which may differ from those set by the image kernel before hibernation. Therefore, the image kernel must ensure the FRED MSRs have the same values as before hibernation. Since these values depend only on the location of the kernel text and data, they can be recomputed from scratch.

[ Upstream commit e255612b5ed9f179abe8196df7c2ba09dd227900 ]

Some operations, like WRITE, does not require FILE_READ_ATTRIBUTES access.

So when FILE_READ_ATTRIBUTES is not explicitly requested for smb2_open_file() then first try to do SMB2 CREATE with FILE_READ_ATTRIBUTES access (like it was before) and then fallback to SMB2 CREATE without FILE_READ_ATTRIBUTES access (less common case).

This change allows to complete WRITE operation to a file when it does not grant FILE_READ_ATTRIBUTES permission and its parent directory does not grant READ_DATA permission (parent directory READ_DATA is implicit grant of child FILE_READ_ATTRIBUTES permission).

[ Upstream commit 287906b20035a04a234d1a3c64f760a5678387be ]

During mount option processing and negotiation with the server, the original user-specified rsize/wsize values were being modified directly. This makes it impossible to recover these values after a connection reset, leading to potential degraded performance after reconnection.

The other problem is that When negotiating read and write sizes, there are cases where the negotiated values might calculate to zero, especially during reconnection when server->max_read or server->max_write might be reset. In general, these values come from the negotiation response. According to MS-SMB2 specification, these values should be at least 65536 bytes.

This patch improves IO parameter handling:

1. Adds vol_rsize and vol_wsize fields to store the original user-specified values separately from the negotiated values 2. Uses got_rsize/got_wsize flags to determine if values were user-specified rather than checking for non-zero values, which is more reliable 3. Adds a prevent_zero_iosize() helper function to ensure IO sizes are never negotiated down to zero, which could happen in edge cases like when server->max_read/write is zero

The changes make the CIFS client more resilient to unusual server responses and reconnection scenarios, preventing potential failures when IO sizes are calculated to be zero.

With commit 11a347fb6cef ("exfat: change to get file size from DataLength"), exfat_get_block() can now handle valid_size. However, most partial unwritten blocks that could be mapped with other blocks are being inefficiently processed separately as individual blocks.

Except for partial unwritten blocks that require independent processing, let's handle them simply as before.

Binary printing functions are using printf() type of format, and compiler is not happy about them as is:

kernel/trace/trace.c:3292:9: error: function ‘trace_vbprintk’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format] kernel/trace/trace_seq.c:182:9: error: function ‘trace_seq_bprintf’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]

Fix the compilation errors by adding __printf() attribute.

While at it, move existing __printf() attributes from the implementations to the declarations. IT also fixes incorrect attribute parameters that are used for trace_array_printk().

TPM2 sessions have been flushed lazily since commit df745e25098dc ("tpm: Lazily flush the auth session"). If /dev/tpm{rm}0 is not accessed in-between two in-kernel calls, it is possible that a TPM2 session is re-started before the previous one has been completed.

This causes a spurios warning in a legit run-time condition, which is also correctly addressed with a fast return path:

[ 2.944047] tpm tpm0: auth session is active

Address the issue by changing dev_warn_once() call to a dev_dbg_once() call.

[ Upstream commit 76d3ca89981354e1f85a3e0ad9ac4217d351cc72 ]

I was wondering why there's garbage at the bottom of the screen when tile blitting is used with an odd mode like 1080, 600 or 200. Sure there's only space for half a tile but the same area is clean when the buffer is bitmap.

Then later I found that it's supposed to be cleaned but that's not implemented. So I took what's in bitblit and adapted it for tileblit.

This implementation was tested for both the horizontal and vertical case, and now does the same as what's done for bitmap buffers.

If anyone is interested to reproduce the problem then I could bet that'd be on a S3 or Ark. Just set up a mode with an odd line count and make sure that the virtual size covers the complete tile at the bottom. E.g. for 600 lines that's 608 virtual lines for a 16 tall tile. Then the bottom area should be cleaned.

For the right side it's more difficult as there the drivers won't let an odd size happen, unless the code is modified. But once it reports back a few pixel columns short then fbcon won't use the last column. With the patch that column is now clean.

Btw. the virtual size should be rounded up by the driver for both axes (not only the horizontal) so that it's dividable by the tile size. That's a driver bug but correcting it is not in scope for this patch.

Implement missing margin clearing for tileblit

Currently ->get_acl() callback always create request for OWNER, GROUP and DACL, even when only DACLs was requested by user. Change API callback to request only information for which the caller asked. Therefore when only DACLs requested, then SMB client will prepare and send DACL-only request.

This change fixes retrieving of "system.cifs_acl" and "system.smb3_acl" xattrs to contain only DACL structure as documented.

Note that setting/changing of "system.cifs_acl" and "system.smb3_acl" xattrs already takes only DACL structure and ignores all other fields.

Previously, the condition for invalidating the tx flow in mctp_i2c_invalidate_tx_flow() checked if `rc` was nonzero. However, this could incorrectly trigger the invalidation even when `rc > 0` was returned as a success status.

This patch updates the condition to explicitly check for `rc < 0`, ensuring that only error cases trigger the invalidation.

In case of an AQR105-based device, create a software node for the mdio function, with a child node for the Aquantia AQR105 PHY, providing a firmware-name (and a bit more, which may be used for future checks) to allow the PHY to load a MAC specific firmware from the file system.

The name of the PHY software node follows the naming convention suggested in the patch for the mdiobus_scan function (in the same patch series).

Consider a process with a group leader L and a sub-thread T. L does sys_exit(1), then T does sys_exit_group(2).

In this case wait_task_zombie(L) will notice SIGNAL_GROUP_EXIT and use L->signal->group_exit_code, this is correct.

But, before that, do_notify_parent(L) called by release_task(T) will use L->exit_code != L->signal->group_exit_code, and this is not consistent. We don't really care, I think that nobody relies on the info which comes with SIGCHLD, if nothing else SIGCHLD < SIGRTMIN can be queued only once.

But pidfs_exit() is more problematic, I think pidfs_exit_info->exit_code should report ->group_exit_code in this case, just like wait_task_zombie().

TODO: with this change we can hopefully cleanup (or may be even kill) the similar SIGNAL_GROUP_EXIT checks, at least in wait_task_zombie().

Using Clement's new validation callbacks, support checking that dependencies have been satisfied for the vector extensions. From the kernel's perfective, it's not required to differentiate between the conditions for all the various vector subsets - it's the firmware's job to not report impossible combinations. Instead, the kernel only has to check that the correct config options are enabled and to enforce its requirement of the d extension being present for FPU support.

Since vector will now be disabled proactively, there's no need to clear the bit in elf_hwcap in riscv_fill_hwcap() any longer.

[ Upstream commit 61c39d8c83e2077f33e0a2c8980a76a7f323f0ce ]

Since:

0c1d7a2c2d32 ("lockdep: Remove softirq accounting on PREEMPT_RT.")

the wait context test for mutex usage within "in softirq context" fails as it references @softirq_context:

| wait context tests | -------------------------------------------------------------------------- | rcu | raw | spin |mutex | -------------------------------------------------------------------------- in hardirq context: ok | ok | ok | ok | in hardirq context (not threaded): ok | ok | ok | ok | in softirq context: ok | ok | ok |FAILED|

As a fix, add lockdep map for BH disabled section. This fixes the issue by letting us catch cases when local_bh_disable() gets called with preemption disabled where local_lock doesn't get acquired. In the case of "in softirq context" selftest, local_bh_disable() was being called with preemption disable as it's early in the boot.

[ boqun: Move the lockdep annotations into __local_bh_*() to avoid false positives because of unpaired local_bh_disable() reported by Borislav Petkov and Peter Zijlstra, and make bh_lock_map only exist for PREEMPT_RT. ]

[ mingo: Restored authorship and improved the bh_lock_map definition. ]

In the critical submission path memory allocations can't wait for reclaim since that can potentially wait for submissions to finish.

Finally clean that up and mark most memory allocations in the critical path with GFP_NOWAIT. The only exception left is the dma_fence_array() used when no VMID is available, but that will be cleaned up later on.

[ Upstream commit 6c4d5aadf5df31ea0ac025980670eee9beaf466b ]

MSI remapping bypass (directly configuring MSI entries for devices on the VMD bus) won't work under Xen, as Xen is not aware of devices in such bus, and hence cannot configure the entries using the pIRQ interface in the PV case, and in the PVH case traps won't be setup for MSI entries for such devices.

Until Xen is aware of devices in the VMD bus prevent the VMD_FEAT_CAN_BYPASS_MSI_REMAP capability from being used when running as any kind of Xen guest.

The MSI remapping bypass is an optional feature of VMD bridges, and hence when running under Xen it will be masked and devices will be forced to redirect its interrupts from the VMD bridge. That mode of operation must always be supported by VMD bridges and works when Xen is not aware of devices behind the VMD bridge.

A user complained that a message such as:

EXT4-fs (nvme0n1p3): re-mounted UUID ro. Quota mode: none.

implied that the file system was previously mounted read/write and was now remounted read-only, when it could have been some other mount state that had changed by the "mount -o remount" operation. Fix this by only logging "ro"or "r/w" when it has changed.

[ Upstream commit 0fb482728ba1ee2130eaa461bf551f014447997c ]

This is another attempt trying to make pidfd polling for multi-threaded exec and premature thread-group leader exit consistent.

A quick recap of these two cases:

(1) During a multi-threaded exec by a subthread, i.e., non-thread-group leader thread, all other threads in the thread-group including the thread-group leader are killed and the struct pid of the thread-group leader will be taken over by the subthread that called exec. IOW, two tasks change their TIDs.

(2) A premature thread-group leader exit means that the thread-group leader exited before all of the other subthreads in the thread-group have exited.

Both cases lead to inconsistencies for pidfd polling with PIDFD_THREAD. Any caller that holds a PIDFD_THREAD pidfd to the current thread-group leader may or may not see an exit notification on the file descriptor depending on when poll is performed. If the poll is performed before the exec of the subthread has concluded an exit notification is generated for the old thread-group leader. If the poll is performed after the exec of the subthread has concluded no exit notification is generated for the old thread-group leader.

The correct behavior would be to simply not generate an exit notification on the struct pid of a subhthread exec because the struct pid is taken over by the subthread and thus remains alive.

But this is difficult to handle because a thread-group may exit prematurely as mentioned in (2). In that case an exit notification is reliably generated but the subthreads may continue to run for an indeterminate amount of time and thus also may exec at some point.

So far there was no way to distinguish between (1) and (2) internally. This tiny series tries to address this problem by discarding PIDFD_THREAD notification on premature thread-group leader exit.

If that works correctly then no exit notifications are generated for a PIDFD_THREAD pidfd for a thread-group leader until all subthreads have been reaped. If a subthread should exec aftewards no exit notification will be generated until that task exits or it creates subthreads and repeates the cycle.

The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be lowered to less than 0.5V for a minimum of 1 ms when powering off a card. Increase wait to 15 ms so that voltage has time to drain down to 0.5V and cards can power off correctly. Issues with voltage drain time were only observed on Apollo Lake and Bay Trail host controllers so this fix is limited to those devices.

cgroup_rstat_flush_locked() grabs the irq safe cgroup_rstat_lock while iterating all possible cpus. It only drops the lock if there is scheduler or spin lock contention. If neither, then interrupts can be disabled for a long time. On large machines this can disable interrupts for a long enough time to drop network packets. On 400+ CPU machines I've seen interrupt disabled for over 40 msec.

Prevent rstat from disabling interrupts while processing all possible cpus. Instead drop and reacquire cgroup_rstat_lock for each cpu. This approach was previously discussed in https://lore.kernel.org/lkml/ZBz%2FV5a7%2F6PZeM7S@slm.duckdns.org/, though this was in the context of an non-irq rstat spin lock.

Benchmark this change with: 1) a single stat_reader process with 400 threads, each reading a test memcg's memory.stat repeatedly for 10 seconds. 2) 400 memory hog processes running in the test memcg and repeatedly charging memory until oom killed. Then they repeat charging and oom killing.

v6.14-rc6 with CONFIG_IRQSOFF_TRACER with stat_reader and hogs, finds interrupts are disabled by rstat for 45341 usec: # => started at: _raw_spin_lock_irq # => ended at: cgroup_rstat_flush # # # _------=> CPU# # / _-----=> irqs-off/BH-disabled # | / _----=> need-resched # || / _---=> hardirq/softirq # ||| / _--=> preempt-depth # |||| / _-=> migrate-disable # ||||| / delay # cmd pid |||||| time | caller # \ / |||||| \ | / stat_rea-96532 52d.... 0us*: _raw_spin_lock_irq stat_rea-96532 52d.... 45342us : cgroup_rstat_flush stat_rea-96532 52d.... 45342us : tracer_hardirqs_on <-cgroup_rstat_flush stat_rea-96532 52d.... 45343us : <stack trace> => memcg1_stat_format => memory_stat_format => memory_stat_show => seq_read_iter => vfs_read => ksys_read => do_syscall_64 => entry_SYSCALL_64_after_hwframe

With this patch the CONFIG_IRQSOFF_TRACER doesn't find rstat to be the longest holder. The longest irqs-off holder has irqs disabled for 4142 usec, a huge reduction from previous 45341 usec rstat finding.

Running stat_reader memory.stat reader for 10 seconds: - without memory hogs: 9.84M accesses => 12.7M accesses - with memory hogs: 9.46M accesses => 11.1M accesses The throughput of memory.stat access improves.

The mode of memory.stat access latency after grouping by of 2 buckets: - without memory hogs: 64 usec => 16 usec - with memory hogs: 64 usec => 8 usec The memory.stat latency improves.

The interrupt status polling is unreliable, which can cause status events to get lost. On all newer chips, txs-timeout is an indication that the packet was either never sent, or never acked. Fixes issues with inactivity polling.

[ Upstream commit 24a295e4ef1ca8e97d8b7015e1887b6e83e1c8be ]

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel.

This can be very confusing when switching between userspace and kernelspace coding, or when dealing with UAPI headers that rather should use __ASSEMBLER__ instead. So let's standardize on the __ASSEMBLER__ macro that is provided by the compilers now.

This is mostly a mechanical patch (done with a simple "sed -i" statement), with some manual tweaks in <asm/frame.h>, <asm/hw_irq.h> and <asm/setup.h> that mentioned this macro in comments with some missing underscores.

[ Upstream commit 7e6b0a2e4152f4046af95eeb46f8b4f9b2a7398d ]

The Family model check to read the processor flag MSR is misleading and potentially incorrect. It doesn't consider Family while comparing the model number. The original check did have a Family number but it got lost/moved during refactoring.

intel_collect_cpu_info() is called through multiple paths such as early initialization, CPU hotplug as well as IFS image load. Some of these flows would be error prone due to the ambiguous check.

Correct the processor flag scan check to use a Family number and update it to a VFM based one to make it more readable.

At least with CONFIG_PHYSICAL_START=0x100000, if there is < 4 MiB of contiguous free memory available at this point, the kernel will crash and burn because memblock_phys_alloc_range() returns 0 on failure, which leads memblock_phys_free() to throw the first 4 MiB of physical memory to the wolves.

At a minimum it should fail gracefully with a meaningful diagnostic, but in fact everything seems to work fine without the weird reserve allocation.

Currently, the async discard machinery owns a ref to the block_group when the block_group is queued on a discard list. However, to handle races with discard cancellation and the discard workfn, we have a specific logic to detect that the block_group is *currently* running in the workfn, to protect the workfn's usage amidst cancellation.

As far as I can tell, this doesn't have any overt bugs (though finish_discard_pass() and remove_from_discard_list() racing can have a surprising outcome for the caller of remove_from_discard_list() in that it is again added at the end).

But it is needlessly complicated to rely on locking and the nullity of discard_ctl->block_group. Simplify this significantly by just taking a refcount while we are in the workfn and unconditionally drop it in both the remove and workfn paths, regardless of if they race.

[BUG] Even after all the error fixes related the "ASSERT(list_empty(&fs_info->delayed_iputs));" in close_ctree(), I can still hit it reliably with my experimental 2K block size.

[CAUSE] In my case, all the error is triggered after the fs is already in error status.

I find the following call trace to be the cause of race:

Main thread | endio_write_workers ---------------------------------------------+--------------------------- close_ctree() | |- btrfs_error_commit_super() | | |- btrfs_cleanup_transaction() | | | |- btrfs_destroy_all_ordered_extents() | | | |- btrfs_wait_ordered_roots() | | |- btrfs_run_delayed_iputs() | | | btrfs_finish_ordered_io() | | |- btrfs_put_ordered_extent() | | |- btrfs_add_delayed_iput() |- ASSERT(list_empty(delayed_iputs)) | !!! Triggered !!!

The root cause is that, btrfs_wait_ordered_roots() only wait for ordered extents to finish their IOs, not to wait for them to finish and removed.

[FIX] Since btrfs_error_commit_super() will flush and wait for all ordered extents, it should be executed early, before we start flushing the workqueues.

And since btrfs_error_commit_super() now runs early, there is no need to run btrfs_run_delayed_iputs() inside it, so just remove the btrfs_run_delayed_iputs() call from btrfs_error_commit_super().

Btrfs utilizes inline data extent for the following cases:

- Regular small files - Symlinks

And "btrfs check" detects any file extents that are too large as an error.

It's not a problem for 4K block size, but for the incoming smaller block sizes (2K), it can cause problems due to bad limits:

- Non-compressed inline data extents We do not allow a non-compressed inline data extent to be as large as block size.

- Symlinks Currently the only real limit on symlinks are 4K, which can be larger than 2K block size.

These will result btrfs-check to report too large file extents.

Fix it by adding proper size checks for the above cases.

[ Upstream commit 1a5b5668d711d3d1ef447446beab920826decec3 ]

Currently reading an inline data extent will zero out the remaining range in the page.

This is not yet causing problems even for block size < page size (subpage) cases because:

1) An inline data extent always starts at file offset 0 Meaning at page read, we always read the inline extent first, before any other blocks in the page. Then later blocks are properly read out and re-fill the zeroed out ranges.

2) Currently btrfs will read out the whole page if a buffered write is not page aligned So a page is either fully uptodate at buffered write time (covers the whole page), or we will read out the whole page first. Meaning there is nothing to lose for such an inline extent read.

But it's still not ideal:

- We're zeroing out the page twice Once done by read_inline_extent()/uncompress_inline(), once done by btrfs_do_readpage() for ranges beyond i_size.

- We're touching blocks that don't belong to the inline extent In the incoming patches, we can have a partial uptodate folio, of which some dirty blocks can exist while the page is not fully uptodate:

The page size is 16K and block size is 4K:

0 4K 8K 12K 16K | | |/////////| |

And range [8K, 12K) is dirtied by a buffered write, the remaining blocks are not uptodate.

If range [0, 4K) contains an inline data extent, and we try to read the whole page, the current behavior will overwrite range [8K, 12K) with zero and cause data loss.

So to make the behavior more consistent and in preparation for future changes, limit the inline data extents read to only zero out the range inside the first block, not the whole page.

Also, while at it, move the WARN_ON() into the if statement's expression, as it makes it clear what is being tested and also has the effect of adding 'unlikely' to the statement, which allows the compiler to generate better code as this condition is never expected to happen.

This patch improve the returned error code of blkcg_policy_register().

1. Move the validation check for cpd/pd_alloc_fn and cpd/pd_free_fn function pairs to the start of blkcg_policy_register(). This ensures we immediately return -EINVAL if the function pairs are not correctly provided, rather than returning -ENOSPC after locking and unlocking mutexes unnecessarily.

Those locks should not contention any problems, as error of policy registration is a super cold path.

2. Return -ENOMEM when cpd_alloc_fn() failed.

[HOW] Defer dispclk optimization until safe_to_lower = true and display_count reaches 0.

Since 0 has a special value in this logic (ie. no dispclk required) we also need adjust the logic that clamps it for the actual request to PMFW.

[ Upstream commit 86947bdc28894520ed5aab0cf21b99ff0b659e07 ]

If vfs_flush() is called with queue frozen, the queue freeze lock may be connected with FS internal lock, and lockdep warning can be triggered because the queue freeze lock is connected with too many global or sub-system locks.

Fix the warning by moving vfs_fsync() out of loop_update_dio():

- vfs_fsync() is only needed when switching to dio

- only loop_change_fd() and loop_configure() may switch from buffered IO to direct IO, so call vfs_fsync() directly here. This way is safe because either loop is in unbound, or new file isn't attached

- for the other two cases of set_status and set_block_size, direct IO can only become off, so no need to call vfs_fsync()

Doing this allows using registers as retrieved from an mcontext to be pushed to a process using PTRACE_SETREGS.

It is not entirely clear to me why CSGSFS was masked. Doing so creates issues when using the mcontext as process state in seccomp and simply copying the register appears to work perfectly fine for ptrace.

Newer FW can set the CAPS_CHANGE flag during ifup if some capabilities or configurations have changed. For example, the CoS queue configurations may have changed. Support this new flag by treating it almost like FW reset. The driver will essentially rediscover all features and capabilities, reconfigure all backing store context memory, reset everything to default, and reserve all resources.

Fixed some formatting specifiers errors, such as using %d for int and %u for unsigned int, as well as other byte-length types.

Perform type cast using the type derived from the data type itself, for example, if it's originally an int, it will be cast to unsigned int if forced to unsigned.

If a journal is wiped, we will set journal->j_tail to 0. However if 'write' argument is not set (as it happens for read-only device or for ocfs2), the on-disk superblock is not updated accordingly and thus jbd2_journal_recover() cat try to recover the wiped journal. Fix the check in jbd2_journal_recover() to use journal->j_tail for checking empty journal instead.

[ Upstream commit 17fdf318f5fbe5c27353ae917c0c5a2899d9c259 ]

The current code for the IRQ in pcm6240 makes no sense: it looks up an IRQ with of_irq_get(), treat it as a GPIO by issuing gpio_request(), gpio_direction_input() and gpio_to_irq() on it.

This is just wrong, if the device tree assigns the IRQ from a GPIO number this is just incorrect: it is clearly stated that GPIO providers and IRQ providers are orthogonal.

It is possible to look up an IRQ to a corresponding GPIO line but this is taking an IRQ and pretending it's a GPIO, which is just semantically wrong.

Drop the offending code and treat the IRQ that we get from the device tree as any other IRQ, see for example other codec drivers.

The DT bindings for this codec does not have any in-tree DTS files, which may explain why things are weird.

As a bonus, this moves the driver away from the legacy <linux/gpio.h> include.

A bug was identified where the KTAP below caused an infinite loop:

The infinite loop was caused by the parser not parsing a test plan if following a test result line.

Fix this bug by parsing test plan line to avoid the infinite loop.

When using smc_pnet in SMC, it will only search the pnetid in the base_ndev of the netdev hierarchy(both HW PNETID and User-defined sw pnetid). This may not work for some scenarios when using SMC in container on cloud environment. In container, there have choices of different container network, such as directly using host network, virtual network IPVLAN, veth, etc. Different choices of container network have different netdev hierarchy. Examples of netdev hierarchy show below. (eth0 and eth1 in host below is the netdev directly related to the physical device). _______________________________ | _________________ | | |POD | | | | | | | | eth0_________ | | | |____| |__| | | | | | | | | | | eth1|base_ndev| eth0_______ | | | | | RDMA || | host |_________| |_______|| --------------------------------- netdev hierarchy if directly using host network ________________________________ | _________________ | | |POD __________ | | | | |upper_ndev| | | | |eth0|__________| | | | |_______|_________| | | |lower netdev | | __|______ | | eth1| | eth0_______ | | |base_ndev| | RDMA || | host |_________| |_______|| --------------------------------- netdev hierarchy if using IPVLAN _______________________________ | _____________________ | | |POD _________ | | | | |base_ndev|| | | |eth0(veth)|_________|| | | |____________|________| | | |pairs | | _______|_ | | | | eth0_______ | | veth|base_ndev| | RDMA || | |_________| |_______|| | _________ | | eth1|base_ndev| | | host |_________| | --------------------------------- netdev hierarchy if using veth Due to some reasons, the eth1 in host is not RDMA attached netdevice, pnetid is needed to map the eth1(in host) with RDMA device so that POD can do SMC-R. Because the eth1(in host) is managed by CNI plugin(such as Terway, network management plugin in container environment), and in cloud environment the eth(in host) can dynamically be inserted by CNI when POD create and dynamically be removed by CNI when POD destroy and no POD related to the eth(in host) anymore. It is hard to config the pnetid to the eth1(in host). But it is easy to config the pnetid to the netdevice which can be seen in POD. When do SMC-R, both the container directly using host network and the container using veth network can successfully match the RDMA device, because the configured pnetid netdev is a base_ndev. But the container using IPVLAN can not successfully match the RDMA device and 0x03030000 fallback happens, because the configured pnetid netdev is not a base_ndev. Additionally, if config pnetid to the eth1(in host) also can not work for matching RDMA device when using veth network and doing SMC-R in POD.

To resolve the problems list above, this patch extends to search user -defined sw pnetid in the clc handshake ndev when no pnetid can be found in the base_ndev, and the base_ndev take precedence over ndev for backward compatibility. This patch also can unify the pnetid setup of different network choices list above in container(Config user-defined sw pnetid in the netdevice can be seen in POD).

Each pin can be configured as a Special Function IO (SFIO) or GPIO, where the SFIO enables the pin to operate in alternative modes such as I2C, SPI, etc.

The current implementation sets all the pins back to SFIO mode even if they were initially in GPIO mode. This can cause glitches on the pins when pinctrl_gpio_free() is called.

Avoid these undesired glitches by storing the pin's SFIO/GPIO state on GPIO request and restoring it on GPIO free.

The chipid macro/variable and regmap_read function call is not needed because the TPS65219_REG_TI_DEV_ID register value is not a consistent value across TPS65219 PMIC config versions. Reading from the DEV_ID register without a consistent value to compare it to isn't useful. There isn't a way to verify the match data ID is the same ID read from the DEV_ID device register. 0xF0 isn't a DEV_ID value consistent across TPS65219 NVM configurations.

For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID register. However, there are other error checks in place within probe() that apply to both PMICs rather than keeping this isolated check for one PMIC.

Just use the default values. There's not need to get the value from hardware and it could cause problems if we do that at runtime and gfxoff is active.

[ Upstream commit a149377c033afe6557c50892ebbfc0e8b7e2e253 ]

Add support for GPIO headphone detection with the hp-det-gpios property. In order for this to properly disable the path upon removal of headphones, the output must be labelled Headphone which is a common sink in the driver.

Describe a headphone jack and detection GPIO in the driver, check for a corresponding device tree node, and enable jack detection in a new machine init function if described.

[ Upstream commit cdbbc480f4146cb659af97f4020601fde5fb65a7 ]

On the QCM6490 boards, the LPASS firmware controls the complete clock controller functionalities and associated power domains. However, only the LPASS resets required to be controlled by the high level OS. Thus, add support for the resets in the clock driver to enable the Audio SW driver to assert/deassert the audio resets as needed.
