[PATCH rtw-next] wifi: rtlwifi: disable ASPM for RTL8723BE with subsystem ID 11ad:1723

by Mingcong Bai

RTL8723BE found on some ASUSTek laptops, such as F441U and X555UQ with subsystem ID 11ad:1723 are known to output large amounts of PCIe AER errors during and after boot up, causing heavy lags and at times lock-ups: pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:00:1c.5 pcieport 0000:00:1c.5: PCIe Bus Error: severity=Correctable, type=Physical Layer, (Receiver ID) pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000 pcieport 0000:00:1c.5: [ 0] RxErr Disable ASPM on this combo as a quirk. This patch is a revision of a previous patch (linked below) which attempted to disable ASPM for RTL8723BE on all Intel Skylake and Kaby Lake PCIe bridges. I take a more conservative approach as all known reports point to ASUSTek laptops of these two generations with this particular wireless card. Please note, however, before the rtl8723be finishes probing, the AER errors remained. After the module finishes probing, all AER errors would indeed be eliminated, along with heavy lags, poor network throughput, and/or occasional lock-ups.

[PATCH RESEND] media: dst_ca: Add error handling for dst_comm_init()

by Wentao Liang

The function dst_ci_command() calls the function dst_comm_init() but does not handle the error if the init fails. A proper implementation can be found in dst_command() in /source/drivers/media/pci/bt8xx/dst.c. Add error handling to the dst_comm_init(). Print an error message via dprintk(), and jump to the 'error' label if the function fails.

[PATCH RESEND] habanalabs: Add error handling for hl_mmu_get_hop_pte_phys_addr()

In _hl_mmu_v2_hr_map(), If hl_mmu_get_hop_pte_phys_addr() fail to get physical address, the return address will be set as U64_MAX.

[PATCH] media: dvb: Add error handling for bcm3510_writeB()

by Wentao Liang

In bcm3510_bert_reset(), the function performed multiple writes without checking the return value of bcm3510_writeB(). Since almost all the bcm3510_writeB() in this driver have check their return value, it is necessary to add an error check for the bcm3510_writeB() in bcm3510_bert_reset().

[PATCH RESEND] drm/amd/display: Add dp_decide_lane_settings() to ensure compatibility

by Wentao Liang

The dp_perform_128b_132b_channel_eq_done_sequence() calls dp_get_lane_status_and_lane_adjust() but lacks dp_decide_lane_settings(). The dp_get_lane_status_and_lane_adjust() and dp_decide_lane_settings() functions are essential for DisplayPort link training in the Linux kernel, with the former retrieving lane status and adjustment needs, and the latter determining optimal lane configurations. This omission risks compatibility issues, particularly with lower-quality cables or displays, as the system cannot dynamically adjust to hardware limitations, potentially leading to failed connections. Add dp_decide_lane_settings() to enable adaptive lane configuration.

Please apply 8dcd71b45df3 to 5.4

by Nathan Chancellor

Hi Greg and Sasha, Please consider applying commit 8dcd71b45df3 ("powerpc/prom_init: Use -ffreestanding to avoid a reference to bcmp") to 5.4, as it resolves an error seen in that branch with a newer version of clang that looks for loops to turn into strlen(), which it is not allowed to do in this early code. It landed in 5.5 so it is in every other stable branch already. Please let me know if there are any issues. Cheers, Nathan

[PATCH v4 RESEND 1/2] HID: amd_sfh: Fix SRA sensor when it's the only sensor

by Mario Limonciello

From: Mario Limonciello <mario.limonciello(a)amd.com> On systems that only have an SRA sensor connected to SFH the sensor doesn't get enabled due to a bad optimization condition of breaking the sensor walk loop. This optimization is unnecessary in the first place because if there is only one device then the loop only runs once. Drop the condition and explicitly mark sensor as enabled.

If the old timer triggers during this window, it may falsely detect a softlockup due to the old interval and the new `watchdog_thresh` value being used. The problem can be described as follow: # We asuume previous watchdog_thresh is 60, so the watchdog timer is # coming every 24s. echo 10 > /proc/sys/kernel/watchdog_thresh (User space) | +------>+ update watchdog_thresh (We are in kernel now) | | # using old interval and new `watchdog_thresh` +------>+ watchdog hrtimer (irq context: detect softlockup) | | +-------+ | | + softlockup_stop_all To fix this problem, introduce a shadow variable for `watchdog_thresh`. The update to the actual `watchdog_thresh` is delayed until after the old timer is stopped, preventing false positives. The following testcase may help to understand this problem. --------------------------------------------- echo RT_RUNTIME_SHARE > /sys/kernel/debug/sched/features echo -1 > /proc/sys/kernel/sched_rt_runtime_us echo 0 > /sys/kernel/debug/sched/fair_server/cpu3/runtime echo 60 > /proc/sys/kernel/watchdog_thresh taskset -c 3 chrt -r 99 /bin/bash -c "while true;do true; done" & echo 10 > /proc/sys/kernel/watchdog_thresh & --------------------------------------------- The test case above first removes the throttling restrictions for real-time tasks. It then sets watchdog_thresh to 60 and executes a real-time task ,a simple while(1) loop, on cpu3. Consequently, the final command gets blocked because the presence of this real-time thread prevents kworker:3 from being selected by the scheduler. This eventually triggers a softlockup detection on cpu3 due to watchdog_timer_fn operating with inconsistent variable - using both the old interval and the updated watchdog_thresh simultaneously.

[PATCH] drm/amdgpu: restrict the hw sched jobs upper bound

by Alexey Nepomnyashih

The amdgpu_sched_hw_submission parameter controls the number of hardware jobs that can be scheduled concurrently per ring. This value is later multiplied by ring->max_dw to compute buffer offsets or command patch regions. If amdgpu_sched_hw_submission is set too high (by user input via module parameter), the multiplication can overflow, resulting in corrupted memory offsets or ring buffer overflows. Clamp amdgpu_sched_hw_submission to a practical upper bound (e.g. 2^16) to prevent arithmetic overflow when computing ring buffer offsets during initialization, especially in jpeg_v1_0_start(). Found by Linux Verification Center (linuxtesting.org) with SVACE.

Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to. Testing indicates writes to other registers are not sufficient to prevent the fatal trap, however the value does not appear to matter. This only needs to happen once after power up, so simply rebooting into a kernel lacking this fix will NOT cause the trap.

Set PCI_DEV_FLAGS_MSIX_TOUCH_ENTRY_DATA_FIRST on the struct pci_dev to work around a bug in the hardware or firmware. For each vector entry in the msix table, niu chips will cause a fatal trap if any registers in that entry are read before that entries' ENTRY_DATA register is written to. Testing indicates writes to other registers are not sufficient to prevent the fatal trap, however the value does not appear to matter. This only needs to happen once after power up, so simply rebooting into a kernel lacking this fix will NOT cause the trap.

[PATCH] iio: accel: adis16201: Use IIO_VAL_INT for temperature scale

by Gabriel Shahrouzi

This is a leftover from the patch: commit cf96ffd8c2ed ("staging:iio:accel:adis16201 move to chan_spec based setup."). Initially *val = 0 and *val2 = -470000. However, they were later changed to -470 and 0 respectively but their return type was not updated. Use correct type as -470 is an integer in the base units.

This means that calling WMI methods on this WMI device is not thread-safe, as concurrent WMI method calls will corrupt the global buffer. Fix this by serializing the WMI method calls using a mutex.

To make this code MTE compatible, let's start using load_unaligned_zeropad() on architectures where it is available (i.e. architectures that define CONFIG_DCACHE_WORD_ACCESS). Because load_unaligned_zeropad() takes care of page boundaries as well as tag granule boundaries, also disable the code preventing crossing page boundaries when using load_unaligned_zeropad().

This will fail if there is not a preexisting directory at that path, and since the directory is deleted subsequent runs of the test will fail. Instead of relying on this hard coded directory name use mktemp to generate a temporary directory to use as a mountpoint, fixing both the assumption and the disruption caused by deleting a preexisting directory. This means that if the relevant cgroup filesystem is not already mounted then we rely on having coreutils (which provides mktemp) installed.

Also the compiler is free to apply any optimizations it wants both to the stores in cpufreq_set_policy() and to the loads in cpufreq_driver_resolve_freq() which may result in additional inconsistencies. To address this, use WRITE_ONCE() when updating policy->min and policy->max in cpufreq_set_policy() and use READ_ONCE() for reading them in cpufreq_driver_resolve_freq(). Moreover, rearrange the update in cpufreq_set_policy() to avoid storing intermediate values in policy->min and policy->max with the help of the observation that their new values are expected to be properly ordered upfront. Also modify cpufreq_driver_resolve_freq() to take the possible reverse ordering of policy->min and policy->max, which may happen depending on the ordering of operations when this function and cpufreq_set_policy() run concurrently, into account by always honoring the max when it turns out to be less than the min (in case it comes from thermal throttling or similar).

Without that synchronization it is theoretically possible that the limits_changed update in sugov_should_update_freq() will be reordered with respect to the reads of the policy limits in cpufreq_driver_resolve_freq() and in that case, if the limits_changed update in sugov_limits() clobbers the one in sugov_should_update_freq(), the new policy limits may not take effect for a long time. Likewise, the limits_changed update in sugov_limits() may theoretically get reordered with respect to the updates of the policy limits in cpufreq_set_policy() and if sugov_should_update_freq() runs between them, the policy limits change may be missed. To ensure that the above situations will not take place, add memory barriers preventing the reordering in question from taking place and add READ_ONCE() and WRITE_ONCE() annotations around all of the limits_changed flag updates to prevent the compiler from messing up with that code.

[PATCH] iio: frequency: Use SLEEP bit instead of RESET to disable output

by Gabriel Shahrouzi

According to the AD9832 datasheet (Table 10, D12 description), setting the RESET bit forces the phase accumulator to zero, which corresponds to a full-scale DC output, rather than disabling the output signal. The correct way to disable the output and enter a low-power state is to set the AD9832_SLEEP bit (Table 10, D13 description), which powers down the internal DAC current sources and disables internal clocks.

[PATCH v5 1/5] staging: iio: adc: ad7816: Allow channel 7 for all devices

by Gabriel Shahrouzi

According to the datasheet on page 9 under the channel selection table, all devices (AD7816/7/8) are able to use the channel marked as 7. This channel is used for diagnostic purposes by routing the internal 1.23V bandgap source through the MUX to the input of the ADC. Modify the channel validation logic to permit channel 7 for all supported device types.

[PATCH v3] mm/huge_memory: fix dereferencing invalid pmd migration entry

by Gavin Guo

When migrating a THP, concurrent access to the PMD migration entry during a deferred split scan can lead to an invalid address access, as illustrated below. To prevent this invalid access, it is necessary to check the PMD migration entry and return early. In this context, there is no need to use pmd_to_swp_entry and pfn_swap_entry_to_page to verify the equality of the target folio. Since the PMD migration entry is locked, it cannot be served as the target. Mailing list discussion and explanation from Hugh Dickins: "An anon_vma lookup points to a location which may contain the folio of interest, but might instead contain another folio: and weeding out those other folios is precisely what the "folio != pmd_folio((*pmd)" check (and the "risk of replacing the wrong folio" comment a few lines above it) is for."

The kernel driver returned CPU frequency for MTL and bare PLL frequency for LNL - this was inconsistent and incorrect for both platforms. With this fix the driver returns maximum frequency of the NPU data processing unit (DPU) for all HW generations. This is what user space always expected. Also do not set CPU frequency in boot params - the firmware does not use frequency passed from the driver, it was only used by the early pre-production firmware. With that we can remove CPU frequency calculation code. Show NPU frequency in FREQ_CHANGE interrupt when frequency tracking is enabled.

[PATCH 00/20] Add support for HEVC and VP9 codecs in decoder

by Dikshita Agarwal

Hi All, This patch series adds initial support for the HEVC(H.265) and VP9 codecs in iris decoder. The objective of this work is to extend the decoder's capabilities to handle HEVC and VP9 codec streams, including necessary format handling and buffer management. In addition, the series also includes a set of fixes to address issues identified during testing of these additional codecs. These patches also address the comments and feedback received from the RFC patches previously sent. I have made the necessary improvements based on the community's suggestions. Changes sinces RFC: - Added additional fixes to address issues identified during further testing. - Moved typo fix to a seperate patch [Neil] - Reordered the patches for better logical flow and clarity [Neil, Dmitry] - Added fixes tag wherever applicable [Neil, Dmitry] - Removed the default case in the switch statement for codecs [Bryan] - Replaced if-else statements with switch-case [Bryan] - Added comments for mbpf [Bryan] - RFC: https://lore.kernel.org/linux-media/20250305104335.3629945-1-quic_dikshita@… These patches are tested on SM8250 and SM8550 with v4l2-ctl and Gstreamer for HEVC and VP9 decoders, at the same time ensured that the existing H264 decoder functionality remains uneffected. Note: 1 of the fluster compliance test is fixed with firmware [1] [1]: https://lore.kernel.org/linux-firmware/1a511921-446d-cdc4-0203-084c88a5dc1e… The result of fluster test on SM8550: 131/147 testcases passed while testing JCT-VC-HEVC_V1 with GStreamer-H.265-V4L2-Gst1.0. The failing test case: - 10 testcases failed due to unsupported 10 bit format. - DBLK_A_MAIN10_VIXS_4 - INITQP_B_Main10_Sony_1 - TSUNEQBD_A_MAIN10_Technicolor_2 - WP_A_MAIN10_Toshiba_3 - WP_MAIN10_B_Toshiba_3 - WPP_A_ericsson_MAIN10_2 - WPP_B_ericsson_MAIN10_2 - WPP_C_ericsson_MAIN10_2 - WPP_E_ericsson_MAIN10_2 - WPP_F_ericsson_MAIN10_2 - 4 testcase failed due to unsupported resolution - PICSIZE_A_Bossen_1 - PICSIZE_B_Bossen_1 - WPP_D_ericsson_MAIN10_2 - WPP_D_ericsson_MAIN_2 - 1 testcase failed as bitstream is invalid (this fails with reference as well) - RAP_B_Bossen_2 - 1 testcase failed due to CRC mismatch - RAP_A_docomo_6 Analysis - First few frames in this discarded by firmware and are sent to driver with 0 filled length.

Where firmware returned all the buffers with previous sequence and has no buffer left to attach the LAST flag to. At the same time, client is not queueing any further buffers, so there is deadlock where client is waiting for LAST flag, while firmware doesn't have any capture buffer to attach LAST flag to. Ideally client should keep queueing the buffers on capture queue untill the LAST flag is received.

[PATCH 0/9] fs: harden anon inodes

by Christian Brauner

* Anonymous inodes currently don't come with a proper mode causing issues in the kernel when we want to add useful VFS debug assert. Fix that by giving them a proper mode and masking it off when we report it to userspace which relies on them not having any mode. * Anonymous inodes currently allow to change inode attributes because the VFS falls back to simple_setattr() if i_op->setattr isn't implemented. This means the ownership and mode for every single user of anon_inode_inode can be changed. Block that as it's either useless or actively harmful. If specific ownership is needed the respective subsystem should allocate anonymous inodes from their own private superblock. * Port pidfs to the new anon_inode_{g,s}etattr() helpers. * Add proper tests for anonymous inode behavior. The anonymous inode specific fixes should ideally be backported to all LTS kernels. Signed-off-by: Christian Brauner <brauner(a)kernel.org> --- Christian Brauner (9): anon_inode: use a proper mode internally pidfs: use anon_inode_getattr() anon_inode: explicitly block ->setattr() pidfs: use anon_inode_setattr() anon_inode: raise SB_I_NODEV and SB_I_NOEXEC selftests/filesystems: add first test for anonymous inodes selftests/filesystems: add second test for anonymous inodes selftests/filesystems: add third test for anonymous inodes selftests/filesystems: add fourth test for anonymous inodes fs/anon_inodes.c | 45 ++++++++++++++ fs/internal.h | 5 ++ fs/libfs.c | 2 +- fs/pidfs.c | 26 +------- tools/testing/selftests/filesystems/.gitignore | 1 + tools/testing/selftests/filesystems/Makefile | 2 +- .../selftests/filesystems/anon_inode_test.c | 69 ++++++++++++++++++++++ 7 files changed, 124 insertions(+), 26 deletions(-) --- base-commit: 0af2f6be1b4281385b618cb86ad946eded089ac8 change-id: 20250407-work-anon_inode-e22bb1a74992

[PATCH] drm/tegra: Assign plane type before registration

by Aaron Kling via B4 Relay

From: Thierry Reding <treding(a)nvidia.com> Changes to a plane's type after it has been registered aren't propagated to userspace automatically. This could possibly be achieved by updating the property, but since we can already determine which type this should be before the registration, passing in the right type from the start is a much better solution.

BUG: perf hardware breakpoint pc value mismatch

by liaochen (A)

Hi all, We found the following issue with Linux v6.12-rc7 on KunPeng920 platform. A very low frequency problem of pc value mismatch occurs when using perf hardware breakpoints to trigger a signal handler and comparing pc from u_context with its desired value. Attached please find the reproducer for this issue. It applies perf events to set a hardware breakpoint to an address while binding a signal to the perf event fd. When stepping into the breakpoint address, the signal handler compares pc value copied from signal ucontext with the real breakpoint address and see if there is a mismatch.

[PATCH v2] usb: cdnsp: Fix issue with resuming from L1

by Pawel Laszczak

In very rare cases after resuming controller from L1 to L0 it reads registers before the clock UTMI have been enabled and as the result driver reads incorrect value. Most of registers are in APB domain clock but some of them (e.g. PORTSC) are in UTMI domain clock. After entering to L1 state the UTMI clock can be disabled. When controller transition from L1 to L0 the port status change event is reported and in interrupt runtime function driver reads PORTSC. During this read operation controller synchronize UTMI and APB domain but UTMI clock is still disabled and in result it reads 0xFFFFFFFF value. To fix this issue driver increases APB timeout value. The issue is platform specific and if the default value of APB timeout is not sufficient then this time should be set Individually for each platform.

[PATCH v3 1/3] iio: frequency: Use SLEEP bit instead of RESET to disable output

by Gabriel Shahrouzi

According to the AD9832 datasheet (Table 10, D12 description), setting the RESET bit forces the phase accumulator to zero, which corresponds to a full-scale DC output, rather than disabling the output signal. The correct way to disable the output and enter a low-power state is to set the AD9832_SLEEP bit (Table 10, D13 description), which powers down the internal DAC current sources and disables internal clocks.
