2025-01-10drm/amd/display: Use HW lock mgr for PSR1Tom Chung

2025-01-10drm/amd/display: Do not elevate mem_type change to full updateLeo Li
[Why] There should not be any need to revalidate bandwidth on memory placement change, since the fb is expected to be pinned to DCN-accessable memory before scanout. For APU it's DRAM, and DGPU, it's VRAM. However, async flips + memory type change needs to be rejected. [How] Do not set lock_and_validation_needed on mem_type change. Instead, reject an async_flip request if the crtc's buffer(s) changed mem_type. This may fix stuttering/corruption experienced with PSR SU and PSR1 panels, if the compositor allocates fbs in both VRAM carveout and GTT and flips between them.

2025-01-10drm/amd/display: Do not wait for PSR disable on vbl enableLeo Li
[Why] Outside of a modeset/link configuration change, we should not have to wait for the panel to exit PSR. Depending on the panel and it's state, it may take multiple frames for it to exit PSR. Therefore, waiting in all scenarios may cause perceived stuttering, especially in combination with faster vblank shutdown. [How] PSR1 disable is hooked up to the vblank enable event, and vice versa. In case of vblank enable, do not wait for panel to exit PSR, but still wait in all other cases. We also avoid a call to unnecessarily change power_opts on disable - this ends up sending another command to dmcub fw. When testing against IGT, some crc tests like kms_plane_alpha_blend and amd_hotplug were failing due to CRC timeouts. This was found to be caused by the early return before HW has fully exited PSR1. Fix this by first making sure we grab a vblank reference, then waiting for panel to exit PSR1, before programming hw for CRC generation.

2025-01-10workqueue: warn if delayed_work is queued to an offlined cpu.Imran Khan
delayed_work submitted to an offlined cpu, will not get executed, after the specified delay if the cpu remains offline. If the cpu never comes online the work will never get executed. checking for online cpu in __queue_delayed_work, does not sound like a good idea because to do this reliably we need hotplug lock and since work may be submitted from atomic contexts, we would have to use cpus_read_trylock. But if trylock fails we would queue the work on any cpu and this may not be optimal because our intended cpu might still be online. Putting a WARN_ON_ONCE for an already offlined cpu, will indicate users of queue_delayed_work_on, if they are (wrongly) trying to queue delayed_work on offlined cpu. Also indicate the problem of using offlined cpu with queue_delayed_work_on, in its description. Signed-off-by: Imran Khan <imran.f.khan@oracle.com> Signed-off-by: Tejun Heo <tj@kernel.org>

2025-01-10drm/amd/display: Reduce accessing remote DPCD overheadWayne Lin
[Why] Observed frame rate get dropped by tool like glxgear. Even though the output to monitor is 60Hz, the rendered frame rate drops to 30Hz lower. It's due to code path in some cases will trigger dm_dp_mst_is_port_support_mode() to read out remote Link status to assess the available bandwidth for dsc maniplation. Overhead of keep reading remote DPCD is considerable. [How] Store the remote link BW in mst_local_bw and use end-to-end full_pbn as an indicator to decide whether update the remote link bw or not.

This check is historical and no longer needed, wait_address is never NULL. These days we rely on the poll_table->_qproc check. NULL if select/poll is not going to sleep, or it already has a data to report, or all waiters have already been registered after the 1st iteration. However, poll_table *p can be NULL, see p9_fd_poll() for example, so we can't remove the "p != NULL" check.

2025-01-10poll_wait: add mb() to fix theoretical race between waitqueue_active() and ↵Oleg Nesterov
.poll() As the comment above waitqueue_active() explains, it can only be used if both waker and waiter have mb()'s that pair with each other. However __pollwait() is broken in this respect. This is not pipe-specific, but let's look at pipe_poll() for example: poll_wait(...); // -> __pollwait() -> add_wait_queue() LOAD(pipe->head); LOAD(pipe->head); In theory these LOAD()'s can leak into the critical section inside add_wait_queue() and can happen before list_add(entry, wq_head), in this case pipe_poll() can race with wakeup_pipe_readers/writers which do smp_mb(); if (waitqueue_active(wq_head)) wake_up_interruptible(wq_head); There are more __pollwait()-like functions (grep init_poll_funcptr), and it seems that at least ep_ptable_queue_proc() has the same problem, so the patch adds smp_mb() into poll_wait().

2025-01-09ipv4: route: fix drop reason being overridden in ip_route_input_slowAntoine Tenart
When jumping to 'martian_destination' a drop reason is always set but that label falls-through the 'e_nobufs' one, overriding the value. The behavior was introduced by the mentioned commit. The logic went from, goto martian_destination; ... martian_destination: ... e_inval: err = -EINVAL; goto out; e_nobufs: err = -ENOBUFS; goto out; to, reason = ...; goto martian_destination; ... martian_destination: ... e_nobufs: reason = SKB_DROP_REASON_NOMEM; goto out; A 'goto out' is clearly missing now after 'martian_destination' to avoid overriding the drop reason.

2025-01-09net: ethernet: ti: cpsw_ale: Fix cpsw_ale_get_field()Sudheer Kumar Doredla
CPSW ALE has 75-bit ALE entries stored across three 32-bit words. The cpsw_ale_get_field() and cpsw_ale_set_field() functions support ALE field entries spanning up to two words at the most. The cpsw_ale_get_field() and cpsw_ale_set_field() functions work as expected when ALE field spanned across word1 and word2, but fails when ALE field spanned across word2 and word3. For example, while reading the ALE field spanned across word2 and word3 (i.e. bits 62 to 64), the word3 data shifted to an incorrect position due to the index becoming zero while flipping. The same issue occurred when setting an ALE entry. This issue has not been seen in practice but will be an issue in the future if the driver supports accessing ALE fields spanning word2 and word3 Fix the methods to handle getting/setting fields spanning up to two words.

2025-01-09scsi: core: Fix command pass through retry regressionMike Christie
scsi_check_passthrough() is always called, but it doesn't check for if a command completed successfully. As a result, if a command was successful and the caller used SCMD_FAILURE_RESULT_ANY to indicate what failures it wanted to retry, we will end up retrying the command. This will cause delays during device discovery because of the command being sent multiple times. For some USB devices it can also cause the wrong device size to be used. This patch adds a check for if the command was successful. If it is we return immediately instead of trying to match a failure.

While the series can only be merged once SBI v3.0 is frozen, these two patches can be independent of SBI v3.0 and can be merged sooner. Hence, these two patches are sent as a separate series. * b4-shazam-merge: drivers/perf: riscv: Do not allow invalid raw event config drivers/perf: riscv: Return error for default case drivers/perf: riscv: Fix Platform firmware event data Link: https://lore.kernel.org/r/20241212-pmu_event_fixes_v2-v2-0-813e8a4f5962@rivosinc.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
2025-01-09drivers/perf: riscv: Do not allow invalid raw event configAtish Patra
The SBI specification allows only lower 48bits of hpmeventX to be configured via SBI PMU. Currently, the driver masks of the higher bits but doesn't return an error. This will lead to an additional SBI call for config matching which should return for an invalid event error in most of the cases. However, if a platform(i.e Rocket and sifive cores) implements a bitmap of all bits in the event encoding this will lead to an incorrect event being programmed leading to user confusion. Report the error to the user if higher bits are set during the event mapping itself to avoid the confusion and save an additional SBI call.
