Re: [PATCH 1/6] drm/dp_mst: Introduce drm_dp_mst_connector_atomic_check() (fwd)

by Julia Lawall

Hello, I don't think you can update the loop index variable in list_for_each_entry, because the mcro uses th index variable to get to the next element. Perhaps list_for_each_entry_safe would be more suitable? julia ---------- Forwarded message ---------- Date: Thu, 20 Sep 2018 04:30:13 +0800 From: kbuild test robot <lkp(a)intel.com> To: kbuild(a)01.org Cc: Julia Lawall <julia.lawall(a)lip6.fr> Subject: Re: [PATCH 1/6] drm/dp_mst: Introduce drm_dp_mst_connector_atomic_check() CC: kbuild-all(a)01.org In-Reply-To: <20180918230637.20700-2-lyude(a)redhat.com> References: <20180918230637.20700-2-lyude(a)redhat.com> TO: Lyude Paul <lyude(a)redhat.com> CC: dri-devel(a)lists.freedesktop.org, nouveau(a)lists.freedesktop.org, intel-gfx(a)lists.freedesktop.org, amd-gfx(a)lists.freedesktop.org CC: David Airlie <airlied(a)linux.ie>, linux-kernel(a)vger.kernel.org, stable(a)vger.kernel.org, Sean Paul <sean(a)poorly.run> Hi Lyude, Thank you for the patch!

[PATCH 00/11] OPP: Don't create multiple OPP tables for devices sharing OPP table

by Viresh Kumar

Hello, Niklas Cassle recently reported some regressions with his Qcom cpufreq driver where he was getting some errors while creating the OPPs tables. After looking into it I realized that the OPP core incorrectly creates multiple OPP tables for the devices even if they are sharing the OPP table in DT. This happens when the request comes using different CPU devices. For example, dev_pm_opp_set_supported_hw() getting called using CPU0 and dev_pm_opp_of_add_table() getting called using CPU1. This series redesigns the internals of the OPP core to fix that. The redesign has simplified the core itself though. @Niklas: Can you please confirm that this series fixes the issues you have reported ? I have already tested it on Hikey960. -- viresh Viresh Kumar (11): OPP: Free OPP table properly on performance state irregularities OPP: Protect dev_list with opp_table lock OPP: Pass index to _of_init_opp_table() OPP: Parse OPP table's DT properties from _of_init_opp_table() OPP: Don't take OPP table's kref for static OPPs OPP: Create separate kref for static OPPs list cpufreq: mvebu: Remove OPPs using dev_pm_opp_remove() OPP: Don't remove dynamic OPPs from _dev_pm_opp_remove_table() OPP: Use a single mechanism to free the OPP table OPP: Prevent creating multiple OPP tables for devices sharing OPP nodes OPP: Pass OPP table to _of_add_opp_table_v{1|2}() drivers/cpufreq/mvebu-cpufreq.c | 9 +- drivers/opp/core.c | 147 ++++++++++++++++--------- drivers/opp/cpu.c | 11 +- drivers/opp/of.c | 186 +++++++++++++++++--------------- drivers/opp/opp.h | 19 ++-- include/linux/pm_opp.h | 6 ++ 6 files changed, 221 insertions(+), 157 deletions(-) -- 2.18.0.rc1.242.g61856ae69a2c

[PATCH] IB/srp: Avoid that sg_reset -d ${srp_device} triggers an infinite loop

by Bart Van Assche

Use different loop variables for the inner and outer loop. This avoids that an infinite loop occurs if there are more RDMA channels than target->req_ring_size.

[PATCH 4.9] MIPS: VDSO: Match data page cache colouring when D$ aliases

by Paul Burton

[ Upstream commit 0f02cfbc3d9e413d450d8d0fd660077c23f67eff ] When a system suffers from dcache aliasing a user program may observe stale VDSO data from an aliased cache line. Notably this can break the expectation that clock_gettime(CLOCK_MONOTONIC, ...) is, as its name suggests, monotonic. In order to ensure that users observe updates to the VDSO data page as intended, align the user mappings of the VDSO data page such that their cache colouring matches that of the virtual address range which the kernel will use to update the data page - typically its unmapped address within kseg0. This ensures that we don't introduce aliasing cache lines for the VDSO data page, and therefore that userland will observe updates without requiring cache invalidation.

[PATCH 05/40] drm/i915: Handle incomplete Z_FINISH for compressed error states

by Chris Wilson

The final call to zlib_deflate(Z_FINISH) may require more output space to be allocated and so needs to re-invoked. Failure to do so in the current code leads to incomplete zlib streams (albeit intact due to the use of Z_SYNC_FLUSH) resulting in the occasional short object capture.

[GIT PULL] ring-buffer: Allow for rescheduling when removing pages

by Steven Rostedt

Linus (aka Greg), Vaibhav Nagarnaik found that modifying the ring buffer size could cause a huge latency in the system because it does a while loop to free pages without releasing the CPU (on non preempt kernels). In a case where there are hundreds of thousands of pages to free it could actually cause a system stall. A properly place cond_resched() solves this issue. Please pull the latest trace-v4.19-rc4 tree, which can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git trace-v4.19-rc4 Tag SHA1: 977e4fb3741e24151a255ee13bd4a1224545ae4e Head SHA1: 83f365554e47997ec68dc4eca3f5dce525cd15c3 Vaibhav Nagarnaik (1): ring-buffer: Allow for rescheduling when removing pages ---- kernel/trace/ring_buffer.c | 2 ++ 1 file changed, 2 insertions(+) --------------------------- commit 83f365554e47997ec68dc4eca3f5dce525cd15c3 Author: Vaibhav Nagarnaik <vnagarnaik(a)google.com> Date: Fri Sep 7 15:31:29 2018 -0700 ring-buffer: Allow for rescheduling when removing pages When reducing ring buffer size, pages are removed by scheduling a work item on each CPU for the corresponding CPU ring buffer. After the pages are removed from ring buffer linked list, the pages are free()d in a tight loop. The loop does not give up CPU until all pages are removed. In a worst case behavior, when lot of pages are to be freed, it can cause system stall. After the pages are removed from the list, the free() can happen while the work is rescheduled.

[PATCH 13/19] mtd: nand: pxa3xx: Fix READOOB implementation

by kostap＠marvell.com

From: Boris Brezillon <boris.brezillon(a)free-electrons.com> In the current driver, OOB bytes are accessed in raw mode, and when a page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the driver must read the whole spare area (64 bytes in case of a 2k page, 16 bytes for a 512 page). The driver was only reading the free OOB bytes, which was leaving some unread data in the FIFO and was somehow leading to a timeout. We could patch the driver to read ->spare_size + ->ecc_size instead of just ->spare_size when READOOB is requested, but we'd better make in-band and OOB accesses consistent. Since the driver is always accessing in-band data in non-raw mode (with the ECC engine enabled), we should also access OOB data in this mode. That's particularly useful when using the BCH engine because in this mode the free OOB bytes are also ECC protected.

[PATCH 5/6] drm/i915: Fix intel_dp_mst_best_encoder()

by Lyude Paul

Currently, i915 appears to rely on blocking modesets on no-longer-present MSTB ports by simply returning NULL for ->best_encoder(), which in turn causes any new atomic commits that don't disable the CRTC to fail. This is wrong however, since we still want to allow userspace to disable CRTCs on no-longer-present MSTB ports by changing the DPMS state to off and this still requires that we retrieve an encoder. So, fix this by always returning a valid encoder regardless of the state of the MST port. Additionally, make intel_dp_mst_atomic_check() simply rely on drm_dp_mst_connector_atomic_check() to prevent new modesets on no-longer-present MSTB ports.

[PATCH 4/6] drm/i915: Skip vcpi allocation for MSTB ports that are gone

by Lyude Paul

Since we need to be able to allow DPMS on->off prop changes after an MST port has disappeared from the system, we need to be able to make sure we can compute a config for the resulting atomic commit. Currently this is impossible when the port has disappeared, since the VCPI slot searching we try to do in intel_dp_mst_compute_config() will fail with -EINVAL. Since the only commits we want to allow on no-longer-present MST ports are ones that shut off display hardware, we already know that no VCPI allocations are needed. So, hardcode the VCPI slot count to 0 when intel_dp_mst_compute_config() is called on an MST port that's gone.

[PATCH 2/6] drm/nouveau: Unbreak nv50_mstc->best_encoder()

by Lyude Paul

As mentioned in the previous commit, we currently prevent new modesets on recently-removed MST connectors by returning no encoder from our ->best_encoder() callback once the MST port has disappeared. This is wrong however, because it prevents legacy modesetting users from being able to disable CRTCs on MST connectors after the connector's respective topology has disappeared. So, fix this by instead using the new drm_dp_mst_connector_atomic_check() helper instead while always returning a valid encoder from ->best_encoder().

[PATCH v5 0/7] mm: Merge hmm into devm_memremap_pages, mark GPL-only

by Dan Williams

Changes since v4 [1]: * Rebase on v4.19-rc3 * Update changelogs and cover letter [1]: https://lkml.org/lkml/2018/7/11/14 --- Hi Andrew, Back from vacation and this series is still top of mind. devm_memremap_pages() is a facility that can create struct page entries for any arbitrary range and give drivers the ability to subvert core aspects of page management. It, and anything derived from it (e.g. hmm, pcip2p, etc...), is an EXPORT_SYMBOL_GPL() interface. I see that commit 31c5bda3a656 "mm: fix exports that inadvertently make put_page() EXPORT_SYMBOL_GPL" was merged ahead of this series to relieve some of the pressure from innocent consumers of put_page(), but now we need this series to address *producers* of device pages. More details and justification in the changelogs. The 0day infrastructure has reported success across 182 configs and this survives the libnvdimm unit test suite. Aside from the controversial bits the diffstat is compelling at: 7 files changed, 138 insertions(+), 328 deletions(-). Note that the series has some minor collisions with Alex's recent series to improve devm_memremap_pages() scalability [2]. So, whichever you take first the other will need a minor rebase.

[PATCH v3] tpm: Restore functionality to xen vtpm driver.

by Boris Ostrovsky

From: "Dr. Greg Wettstein" <greg(a)wind.enjellic.com> Functionality of the xen-tpmfront driver was lost secondary to the introduction of xenbus multi-page support in commit ccc9d90a9a8b ("xenbus_client: Extend interface to support multi-page ring"). In this commit pointer to location of where the shared page address is stored was being passed to the xenbus_grant_ring() function rather then the address of the shared page itself. This resulted in a situation where the driver would attach to the vtpm-stubdom but any attempt to send a command to the stub domain would timeout. A diagnostic finding for this regression is the following error message being generated when the xen-tpmfront driver probes for a device: <3>vtpm vtpm-0: tpm_transmit: tpm_send: error -62 <3>vtpm vtpm-0: A TPM error (-62) occurred attempting to determine the timeouts This fix is relevant to all kernels from 4.1 forward which is the release in which multi-page xenbus support was introduced. Daniel De Graaf formulated the fix by code inspection after the regression point was located.

patch "serial: 8250: Fix clearing FIFOs in RS485 mode again" added to tty-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled serial: 8250: Fix clearing FIFOs in RS485 mode again to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From f6aa5beb45be27968a4df90176ca36dfc4363d37 Mon Sep 17 00:00:00 2001 From: Marek Vasut <marex(a)denx.de> Date: Mon, 3 Sep 2018 02:44:52 +0200 Subject: serial: 8250: Fix clearing FIFOs in RS485 mode again The 8250 FIFOs indeed need to be cleared after stopping transmission in RS485 mode without SER_RS485_RX_DURING_TX flag set. But there are two problems with the approach taken by the previous patch from Fixes tag. First, serial8250_clear_fifos() should clear fifos, but what it really does is it enables the FIFOs unconditionally if present, clears them and then sets the FCR register to zero, which effectively disables the FIFOs. In case the FIFO is disabled, enabling it and clearing it makes no sense and in fact can trigger misbehavior of the 8250 core. Moreover, the FCR register may contain other FIFO configuration bits which may not be writable unconditionally and writing them incorrectly can trigger misbehavior of the 8250 core too. (ie. AM335x UART swallows the first byte and retransmits the last byte twice because of this FCR write). Second, serial8250_clear_and_reinit_fifos() completely reloads the FCR, but what really has to happen at the end of the RS485 transmission is clearing of the FIFOs and nothing else. This patch repairs serial8250_clear_fifos() so that it really only clears the FIFOs by operating on FCR[2:1] bits and leaves all the other bits alone.
