Hi Dave and Simona, drm-xe-fixes for 6.12-rc2. A few fixes, particularly on error paths and corner cases. We have more than usual as I decided to skip last week pull request. Some tuning for Xe2 were missing and also got updated to match the spec. Thanks Lucas De Marchi drm-xe-fixes-2024-10-03: Driver Changes: - Restore pci state on resume (Rodrigo Vivi) - Fix locking on submission, queue and vm (Matthew Auld, Matthew Brost) - Fix UAF on queue destruction (Matthew Auld) - Fix resource release on freq init error path (He Lugang) - Use rw_semaphore to reduce contention on ASID->VM lookup (Matthew Brost) - Fix steering for media on Xe2_HPM (Gustavo Sousa) - Tuning updates to Xe2 (Gustavo Sousa) - Resume TDR after GT reset to prevent jobs running forever (Matthew Brost) - Move id allocation to avoid userspace using a guessed number to trigger UAF (Matthew Auld, Matthew Brost) - Fix OA stream close preventing pbatch buffers to complete (José) - Fix NPD when migrating memory on LNL (Zhanjun Dong) - Fix memory leak when aborting binds (Matthew Brost) The following changes since commit 9852d85ec9d492ebef56dc5f229416c925758edc: Linux 6.12-rc1 (2024-09-29 15:06:19 -0700) are available in the Git repository at: https://gitlab.freedesktop.org/drm/xe/kernel.git tags/drm-xe-fixes-2024-10-03 for you to fetch changes up to a6f3b2527375c786f2eff77d3ee8b805bcfe026d: drm/xe: Fix memory leak when aborting binds (2024-10-03 01:24:54 -0500) ---------------------------------------------------------------- Driver Changes: - Restore pci state on resume (Rodrigo Vivi) - Fix locking on submission, queue and vm (Matthew Auld, Matthew Brost) - Fix UAF on queue destruction (Matthew Auld) - Fix resource release on freq init error path (He Lugang) - Use rw_semaphore to reduce contention on ASID->VM lookup (Matthew Brost) - Fix steering for media on Xe2_HPM (Gustavo Sousa) - Tuning updates to Xe2 (Gustavo Sousa) - Resume TDR after GT reset to prevent jobs running forever (Matthew Brost) - Move id allocation to avoid userspace using a guessed number to trigger UAF (Matthew Auld, Matthew Brost) - Fix OA stream close preventing pbatch buffers to complete (José) - Fix NPD when migrating memory on LNL (Zhanjun Dong) - Fix memory leak when aborting binds (Matthew Brost) ---------------------------------------------------------------- Gustavo Sousa (3): drm/xe/mcr: Use Xe2_LPM steering tables for Xe2_HPM drm/xe/xe2: Extend performance tuning to media GT drm/xe/xe2: Add performance tuning for L3 cache flushing He Lugang (1): drm/xe: use devm_add_action_or_reset() helper José Roberto de Souza (1): drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close Matthew Auld (4): drm/xe/guc_submit: add missing locking in wedged_fini drm/xe: fix UAF around queue destruction drm/xe/vm: move xa_alloc to prevent UAF drm/xe/queue: move xa_alloc to prevent UAF Matthew Brost (5): drm/xe: Convert to USM lock to rwsem drm/xe: Use helper for ASID -> VM in GPU faults and access counters drm/xe: Resume TDR after GT reset drm/xe: Clean up VM / exec queue file lock usage. drm/xe: Fix memory leak when aborting binds Rodrigo Vivi (1): drm/xe: Restore pci state upon resume Zhanjun Dong (1): drm/xe: Prevent null pointer access in xe_migrate_copy drivers/gpu/drm/xe/regs/xe_gt_regs.h | 11 ++++++++++ drivers/gpu/drm/xe/xe_bo.c | 4 ++-- drivers/gpu/drm/xe/xe_device.c | 12 +++++------ drivers/gpu/drm/xe/xe_device_types.h | 19 +++++++++++++---- drivers/gpu/drm/xe/xe_drm_client.c | 9 +++++++- drivers/gpu/drm/xe/xe_exec_queue.c | 6 +++--- drivers/gpu/drm/xe/xe_gpu_scheduler.c | 5 +++++ drivers/gpu/drm/xe/xe_gpu_scheduler.h | 2 ++ drivers/gpu/drm/xe/xe_gt_freq.c | 4 ++-- drivers/gpu/drm/xe/xe_gt_mcr.c | 2 +- drivers/gpu/drm/xe/xe_gt_pagefault.c | 39 +++++++++++++++++++---------------- drivers/gpu/drm/xe/xe_gt_sysfs.c | 2 +- drivers/gpu/drm/xe/xe_guc_submit.c | 37 ++++++++++++++++++++++++++++++--- drivers/gpu/drm/xe/xe_guc_types.h | 2 ++ drivers/gpu/drm/xe/xe_oa.c | 9 +++----- drivers/gpu/drm/xe/xe_pci.c | 2 ++ drivers/gpu/drm/xe/xe_pt.c | 2 +- drivers/gpu/drm/xe/xe_tuning.c | 28 +++++++++++++++++++++++++ drivers/gpu/drm/xe/xe_vm.c | 28 +++++++++++-------------- 19 files changed, 159 insertions(+), 64 deletions(-)
