[PATCH v2 0/2] drm/msm/dpu: two fixes targeting 6.11

by Dmitry Baryshkov

Leonard Lausen reported an issue with suspend/resume of the sc7180 devices. Fix the WB atomic check, which caused the issue. Also make sure that DPU debugging logs are always directed to the drm_debug / DRIVER so that usual drm.debug masks work in an expected way. Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org> --- Changes in v2: - Reworked the writeback to just drop the connector->status check. - Expanded commit message for the debugging patch. - Link to v1: https://lore.kernel.org/r/20240709-dpu-fix-wb-v1-0-448348bfd4cb@linaro.org --- Dmitry Baryshkov (2): drm/msm/dpu1: don't choke on disabling the writeback connector drm/msm/dpu: don't play tricks with debug macros drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 14 ++------------ drivers/gpu/drm/msm/disp/dpu1/dpu_writeback.c | 3 --- 2 files changed, 2 insertions(+), 15 deletions(-) --- base-commit: 668d33c9ff922c4590c58754ab064aaf53c387dd change-id: 20240709-dpu-fix-wb-6cd57e3eb182 Best regards, -- Dmitry Baryshkov <dmitry.baryshkov(a)linaro.org>

drm/amd/display: Pass pwrseq inst for backlight and ABM

by Alex Deucher

Hi Greg, Sasha, Please cherry pick upstream commit b17ef04bf3a4 ("drm/amd/display: Pass pwrseq inst for backlight and ABM") to stable kernel 6.6.x and newer. This fixes broken backlight adjustment on some AMD platforms with eDP panels. Thanks, Alex

[PATCH V2 1/3] MIPS: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK

by Huacai Chen

When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected, cpu_max_bits_warn() generates a runtime warning similar as below while we show /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit) instead of NR_CPUS to iterate CPUs.

[PATCH v4] memfd: `MFD_NOEXEC_SEAL` should not imply `MFD_ALLOW_SEALING`

by Barnabás Pőcze

`MFD_NOEXEC_SEAL` should remove the executable bits and set `F_SEAL_EXEC` to prevent further modifications to the executable bits as per the comment in the uapi header file: not executable and sealed to prevent changing to executable However, commit 105ff5339f498a ("mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXEC") that introduced this feature made it so that `MFD_NOEXEC_SEAL` unsets `F_SEAL_SEAL`, essentially acting as a superset of `MFD_ALLOW_SEALING`. Nothing implies that it should be so, and indeed up until the second version of the of the patchset[0] that introduced `MFD_EXEC` and `MFD_NOEXEC_SEAL`, `F_SEAL_SEAL` was not removed, however, it was changed in the third revision of the patchset[1] without a clear explanation. This behaviour is surprising for application developers, there is no documentation that would reveal that `MFD_NOEXEC_SEAL` has the additional effect of `MFD_ALLOW_SEALING`. Additionally, combined with `vm.memfd_noexec=2` it has the effect of making all memfds initially sealable. So do not remove `F_SEAL_SEAL` when `MFD_NOEXEC_SEAL` is requested, thereby returning to the pre-Linux 6.3 behaviour of only allowing sealing when `MFD_ALLOW_SEALING` is specified. Now, this is technically a uapi break. However, the damage is expected to be minimal. To trigger user visible change, a program has to do the following steps: - create memfd: - with `MFD_NOEXEC_SEAL`, - without `MFD_ALLOW_SEALING`; - try to add seals / check the seals. But that seems unlikely to happen intentionally since this change essentially reverts the kernel's behaviour to that of Linux <6.3, so if a program worked correctly on those older kernels, it will likely work correctly after this change. I have used Debian Code Search and GitHub to try to find potential breakages, and I could only find a single one. dbus-broker's memfd_create() wrapper is aware of this implicit `MFD_ALLOW_SEALING` behaviour, and tries to work around it[2]. This workaround will break. Luckily, this only affects the test suite, it does not affect the normal operations of dbus-broker. There is a PR with a fix[3]. I also carried out a smoke test by building a kernel with this change and booting an Arch Linux system into GNOME and Plasma sessions. There was also a previous attempt to address this peculiarity by introducing a new flag[4].

Re: Bluetooth kernel BUG with Intel AX211 (regression in 6.1.83)

[PATCH v7 bpf-next 01/10] lib/buildid: harden build ID parsing logic

by Andrii Nakryiko

Harden build ID parsing logic, adding explicit READ_ONCE() where it's important to have a consistent value read and validated just once. Also, as pointed out by Andi Kleen, we need to make sure that entire ELF note is within a page bounds, so move the overflow check up and add an extra note_size boundaries validation. Fixes tag below points to the code that moved this code into lib/buildid.c, and then subsequently was used in perf subsystem, making this code exposed to perf_event_open() users in v5.12+.

[PATCH 0/2] usb: dwc3: Disable susphy during initialization

by Thinh Nguyen

We notice some platforms set "snps,dis_u3_susphy_quirk" and "snps,dis_u2_susphy_quirk" when they should not need to. Just make sure that the GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY are clear during initialization. The host initialization involved xhci. So the dwc3 needs to implement the xhci_plat_priv->plat_start() for xhci to re-enable the suspend bits. Since there's a prerequisite patch to drivers/usb/host/xhci-plat.h that's not a fix patch, this series should go on Greg's usb-testing branch instead of usb-linus.

I have not succeeded in reproducing the problem yet. I tried an AMD based system lent to me, but it's probably the wrong generation (AMD EPYC 7251) and I didn't see the problem. I have a line on a system that's more in line with the systems the bug was reported on that I should be able to try tomorrow. I would love to have some direction from the community at large on this. The fact that nogbpages on the command line causes the same problem without my patch suggests it's not bad code directly in my patch, but something in the way kexec reacts to the resulting identity map. One quick solution would be a kernel command line parameter to select between the previous identity map creation behavior and the new behavior. E.g. in addition to "nogbpages", we could have "somegbpages" and "allgbpages" -- or gbpages=[all, some, none] with nogbpages a synonym for backwards compatibility. But I don't want to introduce a new command line parameter if the actual problem can be understood and fixed. The question is how much time do I have to persue a direct fix before some other action needs to be taken? Thanks, --> Steve Wahl -- Steve Wahl, Hewlett Packard Enterprise
