[PATCH v2] drm/nouveau/gr: enable memory loads on helper invocation on all channels

by Karol Herbst

We have a lurking bug where Fragment Shader Helper Invocations can't load from memory. But this is actually required in OpenGL and is causing random hangs or failures in random shaders. It is unknown how widespread this issue is, but shaders hitting this can end up with infinite loops. We enable those only on all Kepler and newer GPUs where we use our own Firmware. Nvidia's firmware provides a way to set a kernelspace controlled list of mmio registers in the gr space from push buffers via MME macros. v2: drop code for gm200 and newer.

Re: [PATCH 1/1] tpm: disable hwrng for fTPM on some AMD designs

by Linus Torvalds

On Mon, 31 Jul 2023 at 03:53, Jarkko Sakkinen <jarkko(a)kernel.org> wrote: > > I quickly carved up a patch (attached), which is only compile tested > because I do not have any AMD hardware at hand. Is there some way to just see "this is a fTPM"? Because honestly, even if AMD is the one that has had stuttering issues, the bigger argument is that there is simply no _point_ in supporting randomness from a firmware source. There is no way anybody should believe that a firmware TPM generates better randomness than we do natively. And there are many reasons to _not_ believe it. The AMD problem is just the most user-visible one. Now, I'm not saying that a fTPM needs to be disabled in general - but I really feel like we should just do static int tpm_add_hwrng(struct tpm_chip *chip) { if (!IS_ENABLED(CONFIG_HW_RANDOM_TPM)) return 0; // If it's not hardware, don't treat it as such if (tpm_is_fTPM(chip)) return 0; [...] and be done with it. But hey, if we have no way to see that whole "this is firmware emulation", then just blocking AMD might be the only way. Linus

[PATCH V6 net] net: mana: Fix MANA VF unload when hardware is

by Souradeep Chakrabarti

When unloading the MANA driver, mana_dealloc_queues() waits for the MANA hardware to complete any inflight packets and set the pending send count to zero. But if the hardware has failed, mana_dealloc_queues() could wait forever. Fix this by adding a timeout to the wait. Set the timeout to 120 seconds, which is a somewhat arbitrary value that is more than long enough for functional hardware to complete any sends.

Fwd: vmalloc error: btrfs-delalloc btrfs_work_helper [btrfs] in kernel 6.3.x

by Bagas Sanjaya

Hi, I notice a regression report on Bugzilla [1]. Quoting from it: > after updating from 6.2.x to 6.3.x, vmalloc error messages started to appear in the dmesg > > > > # free > total used free shared buff/cache available > Mem: 16183724 1473068 205664 33472 14504992 14335700 > Swap: 16777212 703596 16073616 > > > (zswap enabled) See bugzilla for the full thread and attached dmesg. On the report, the reporter can't perform the required bisection, unfortunately. Anyway, I'm adding it to regzbot: #regzbot introduced: v6.2..v6.3 https://bugzilla.kernel.org/show_bug.cgi?id=217466 #regzbot title: btrfs_work_helper dealloc error in v6.3.x Thanks.

[PATCH] drm/amdgpu: Always emit GDS switch when GDS/GWS/OA is used

by Friedrich Vock

During gfxoff, the per-VMID GDS registers are reset and not restored afterwards. The kernel needs to emit a GDS switch to manually update the GWS registers in this case. Since gfxoff can happen between any two submissions and the kernel has no way of knowing, emit the GDS switch before every submission.

[PATCH 0/6] make vma locking more obvious

by Suren Baghdasaryan

During recent vma locking patch reviews Linus and Jann Horn noted a number of issues with vma locking and suggested improvements: 1. walk_page_range() does not have ability to write-lock a vma during the walk when it's done under mmap_write_lock. For example s390_reset_cmma(). 2. Vma locking is hidden inside vm_flags modifiers and is hard to follow. Suggestion is to change vm_flags_reset{_once} to assert that vma is write-locked and require an explicit locking. 3. Same issue with vma_prepare() hiding vma locking. 4. In userfaultfd vm_flags are modified after vma->vm_userfaultfd_ctx and page faults can operate on a context while it's changed. 5. do_brk_flags() and __install_special_mapping() not locking a newly created vma before adding it into the mm. While not strictly a problem, this is fragile if vma is modified after insertion, as in the mmap_region() case which was recently fixed. Suggestion is to always lock a new vma before inserting it and making it visible to page faults. 6. vma_assert_write_locked() for CONFIG_PER_VMA_LOCK=n would benefit from being mmap_assert_write_locked() instead of no-op and then any place which operates on a vma and calls mmap_assert_write_locked() can be converted into vma_assert_write_locked(). I CC'ed stable only on the first patch because others are cleanups and the bug in userfaultfd does not affect stable (lock_vma_under_rcu prevents uffds from being handled under vma lock protection). However I would be happy if the whole series is merged into stable 6.4 since it makes vma locking more maintainable. The patches apply cleanly over Linus' ToT and will conflict when applied over mm-unstable due to missing [1]. The conflict can be easily resolved by ignoring conflicting deletions but probably simpler to take [1] into mm-unstable and avoid later conflict.

[PATCH] dmaengine: pl330: Return DMA_PAUSED when transaction is paused

by Ilpo Järvinen

pl330_pause() does not set anything to indicate paused condition which causes pl330_tx_status() to return DMA_IN_PROGRESS. This breaks 8250 DMA flush after the fix in commit 57e9af7831dc ("serial: 8250_dma: Fix DMA Rx rearm race"). The function comment for pl330_pause() claims pause is supported but resume is not which is enough for 8250 DMA flush to work as long as DMA status reports DMA_PAUSED when appropriate. Add PAUSED state for descriptor and mark BUSY descriptors with PAUSED in pl330_pause(). Return DMA_PAUSED from pl330_tx_status() when the descriptor is PAUSED.

[PATCH] fs/proc/kcore: reinstate bounce buffer for KCORE_TEXT regions

by Lorenzo Stoakes

Some architectures do not populate the entire range categorised by KCORE_TEXT, so we must ensure that the kernel address we read from is valid. Unfortunately there is no solution currently available to do so with a purely iterator solution so reinstate the bounce buffer in this instance so we can use copy_from_kernel_nofault() in order to avoid page faults when regions are unmapped. This change partly reverts commit 2e1c0170771e ("fs/proc/kcore: avoid bounce buffer for ktext data"), reinstating the bounce buffer, but adapts the code to continue to use an iterator.
