2023-06-15selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSETAlex Maftei
Previously, timestamps were printed using "%lld.%u" which is incorrect for nanosecond values lower than 100,000,000 as they're fractional digits, therefore leading zeros are meaningful. This patch changes the format strings to "%lld.%09u" in order to add leading zeros to the nanosecond value.

2023-06-15drm/dp_mst: Clear MSG_RDY flag before sending new messageWayne Lin
[Why] The sequence for collecting down_reply from source perspective should be: Request_n->repeat (get partial reply of Request_n->clear message ready flag to ack DPRX that the message is received) till all partial replies for Request_n are received->new Request_n+1. Now there is chance that drm_dp_mst_hpd_irq() will fire new down request in the tx queue when the down reply is incomplete. Source is restricted to generate interveleaved message transactions so we should avoid it. Also, while assembling partial reply packets, reading out DPCD DOWN_REP Sideband MSG buffer + clearing DOWN_REP_MSG_RDY flag should be wrapped up as a complete operation for reading out a reply packet. Kicking off a new request before clearing DOWN_REP_MSG_RDY flag might be risky. e.g. If the reply of the new request has overwritten the DPRX DOWN_REP Sideband MSG buffer before source writing one to clear DOWN_REP_MSG_RDY flag, source then unintentionally flushes the reply for the new request. Should handle the up request in the same way. [How] Separete drm_dp_mst_hpd_irq() into 2 steps. After acking the MST IRQ event, driver calls drm_dp_mst_hpd_irq_send_new_request() and might trigger drm_dp_mst_kick_tx() only when there is no on going message transaction. Changes since v1: * Reworked on review comments received -> Adjust the fix to let driver explicitly kick off new down request when mst irq event is handled and acked -> Adjust the commit message Changes since v2: * Adjust the commit message * Adjust the naming of the divided 2 functions and add a new input parameter "ack". * Adjust code flow as per review comments. Changes since v3: * Update the function description of drm_dp_mst_hpd_irq_handle_event Changes since v4: * Change ack of drm_dp_mst_hpd_irq_handle_event() to be an array align the size of esi[] Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2023-06-15dm: use op specific max_sectors when splitting abnormal ioMike Snitzer
Split abnormal IO in terms of the corresponding operation specific max_sectors (max_discard_sectors, max_secure_erase_sectors or max_write_zeroes_sectors). This fixes a significant dm-thinp discard performance regression that was introduced with commit e2dd8aca2d76 ("dm bio prison v1: improve concurrent IO performance"). Relative to discard: max_discard_sectors is used instead of max_sectors; which fixes excessive discard splitting (e.g. max_sectors=128K vs max_discard_sectors=64M). Tested by discarding an 1 Petabyte dm-thin device: lvcreate -V 1125899906842624B -T test/pool -n thin time blkdiscard /dev/test/thin Before this fix (splitting discards every 128K): ~116m After this fix (splitting discards every 64M) : 0m33.460s Reported-by: Zorro Lang <zlang@redhat.com> Fixes: 06961c487a33 ("dm: split discards further if target sets max_discard_granularity") Requires: 13f6facf3fae ("dm: allow targets to require splitting WRITE_ZEROES and SECURE_ERASE") Fixes: e2dd8aca2d76 ("dm bio prison v1: improve concurrent IO performance") Signed-off-by: Mike Snitzer <snitzer@kernel.org>
2023-06-15dm thin: fix issue_discard to pass GFP_NOIO to __blkdev_issue_discardMike Snitzer
issue_discard() passes GFP_NOWAIT to __blkdev_issue_discard() despite its code assuming bio_alloc() always succeeds. Commit 3dba53a958a75 ("dm thin: use __blkdev_issue_discard for async discard support") clearly shows where things went bad: Before commit 3dba53a958a75, dm-thin.c's open-coded __blkdev_issue_discard_async() properly handled using GFP_NOWAIT.

As described in commit 38d11da522aa ("dm: don't lock fs when the map is NULL in process of resume"), a deadlock may be triggered between do_resume() and do_mount(). This commit preserves the fix from commit 38d11da522aa but moves it to where it also serves to fix a similar deadlock between do_suspend() and do_mount(). It does so, if the active map is NULL, by clearing DM_SUSPEND_LOCKFS_FLAG in dm_suspend() which is called by both do_suspend() and do_resume().

2023-06-15drm/amdkfd: bump kfd ioctl minor version for event age availabilityJames Zhu
Bump the minor version to declare event age tracking feature is now available. In kernel amdgpu driver, kfd_wait_on_events is used to support user space signal event wait function. For multiple threads waiting on same event scenery, race condition could occur since some threads after checking signal condition, before calling kfd_wait_on_events, the event interrupt could be fired and wake up other thread which are sleeping on this event. Then those threads could fall into sleep without waking up again. Adding event age tracking in both kernel and user mode, will help avoiding this race condition.

The fixed commit listed in the Fixes tag below, introduced a bug in amdgpu_ras.c::amdgpu_reserve_page_direct(), in that when introducing the new amdgpu_umc_fill_error_record() and internally in that new function the physical address (argument "uint64_t retired_page"--wrong name) is right-shifted by AMDGPU_GPU_PAGE_SHIFT. Thus, in amdgpu_reserve_page_direct() when we pass "address" to that new function, we should NOT right-shift it, since this results, erroneously, in the page address to be 0 for first 2^(2*AMDGPU_GPU_PAGE_SHIFT) memory addresses.

Report the number of records stored in the RAS EEPROM table in debugfs.

See commit 7fb640714547 ("drm/amdgpu: Add bad_page_cnt_threshold to debugfs"). ras_num_recs can already be inferred by dumping the RAS EEPROM table, also in the same debugfs location, see commit reference c65b0805e77919 (drm/amdgpu: RAS EEPROM table is now in debugfs, 2021-04-08). This commit makes it an integer value easily shown in a single file.
