2023-01-12drm: Optimize drm buddy top-down allocation methodArunpravin Paneer Selvam1-27/+54
We are observing performance drop in many usecases which include games, 3D benchmark applications,etc.. To solve this problem, We are strictly not allowing top down flag enabled allocations to steal the memory space from cpu visible region. The idea is, we are sorting each order list entries in ascending order and compare the last entry of each order list in the freelist and return the max block. This patch improves the 3D benchmark scores and solves fragmentation issues.

After applying an engine reset, on some platforms like Jasperlake, we occasionally detect that the engine state is not cleared until shortly after the resume. As we try to resume the engine with volatile internal state, the first request fails with a spurious CS event (it looks like it reports a lite-restore to the hung context, instead of the expected idle->active context switch).

2023-01-09drm/vmwgfx: Remove rcu locks from user resourcesZack Rusin6-233/+87
User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was easy to make the driver crash by submitting command buffers from two different threads. Because the lookups never show up in performance profiles replace them with a regular spin lock which fixes the races in accesses to those shared resources.

2023-01-04drm/i915/gvt: fix double free bug in split_2MB_gtt_entryZheng Wang1-4/+13
If intel_gvt_dma_map_guest_page failed, it will call ppgtt_invalidate_spt, which will finally free the spt. But the caller function ppgtt_populate_spt_by_guest_entry does not notice that, it will free spt again in its error path. Fix this by canceling the mapping of DMA address and freeing sub_spt. Besides, leave the handle of spt destroy to caller function instead of callee function when error occurs.

2023-01-03drm/msm/dp: do not complete dp_aux_cmd_fifo_tx() if irq is not for aux transferKuogee Hsieh1-0/+4
There are 3 possible interrupt sources are handled by DP controller, HPDstatus, Controller state changes and Aux read/write transaction. At every irq, DP controller have to check isr status of every interrupt sources and service the interrupt if its isr status bits shows interrupts are pending. There is potential race condition may happen at current aux isr handler implementation since it is always complete dp_aux_cmd_fifo_tx() even irq is not for aux read or write transaction. This may cause aux read transaction return premature if host aux data read is in the middle of waiting for sink to complete transferring data to host while irq happen. This will cause host's receiving buffer contains unexpected data. This patch fixes this problem by checking aux isr and return immediately at aux isr handler if there are no any isr status bits set. Current there is a bug report regrading eDP edid corruption happen during system booting up. After lengthy debugging to found that VIDEO_READY interrupt was continuously firing during system booting up which cause dp_aux_isr() to complete dp_aux_cmd_fifo_tx() prematurely to retrieve data from aux hardware buffer which is not yet contains complete data transfer from sink. This cause edid corruption. Follows are the signature at kernel logs when problem happen, EDID has corrupt header panel-simple-dp-aux aux-aea0000.edp: Couldn't identify panel via EDID Changes in v2: -- do complete if (ret == IRQ_HANDLED) ay dp-aux_isr() -- add more commit text Changes in v3: -- add Stephen suggested -- dp_aux_isr() return IRQ_XXX back to caller -- dp_ctrl_isr() return IRQ_XXX back to caller Changes in v4: -- split into two patches Changes in v5: -- delete empty line between tags Changes in v6: -- remove extra "that" and fixed line more than 75 char at commit text Fixes: c943b4948b58 ("drm/msm/dp: add displayPort driver support") Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Tested-by: Douglas Anderson <dianders@chromium.org> Reviewed-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/516121/ Link: https://lore.kernel.org/r/1672193785-11003-2-git-send-email-quic_khsieh@quicinc.com Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com>

2023-01-03drm/scheduler: Fix lockup in drm_sched_entity_kill()Dmitry Osipenko2-3/+3
The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.

ipu_src_rect_width() was introduced to support odd screen resolutions such as 1366x768 by internally rounding up primary plane width to a multiple of 8 and compensating with reduced horizontal blanking. This also caused overlay plane width to be rounded up, which was not intended. Fix overlay plane width by limiting the rounding up to the primary plane. drm_rect_width(&new_state->src) >> 16 is the same value as drm_rect_width(dst) because there is no plane scaling support.

2023-01-02drm/scheduler: Fix lockup in drm_sched_entity_kill()Dmitry Osipenko2-3/+3
The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.

2023-01-02drm/meson: Reduce the FIFO lines held when AFBC is not usedCarlo Caione1-3/+2
Having a bigger number of FIFO lines held after vsync is only useful to SoCs using AFBC to give time to the AFBC decoder to be reset, configured and enabled again. For SoCs not using AFBC this, on the contrary, is causing on some displays issues and a few pixels vertical offset in the displayed image. Conditionally increase the number of lines held after vsync only for SoCs using AFBC, leaving the default value for all the others.
