sometimes GPU is switched to other VFs and won't swich back soon, so the kiq reg access will not signal within a short period, instead of busy waiting a long time(MAX_KEQ_REG_WAIT) and returning TMO we can istead sleep 5ms and try again later (non irq context) And since the waiting in kiq_r/weg is busy wait, so MAX_KIQ_REG_WAIT shouldn't set to a long time, set it to 10ms is more appropriate. if gpu already in reset state, don't retry the KIQ reg access otherwise it would always hang because KIQ was already die usually. v2: replace schedule() with msleep() for the wait v3: use while loop for the wait repeating use macros for the sleep period more description for it v4: drop unused variable Signed-off-by:

1)create a routine "handle_vram_lost" to do the vram recovery, and put it into amdgpu_device_reset/reset_sriov, this way no need of the extra paramter to hold the VRAM LOST information and the related macros can be removed. 3)show vram_recover failure if time out, and set TMO equal to lockup_timeout if vram_recover is under SRIOV runtime mode. 4)report error if any ip reset failed for SR-IOV Signed-off-by:

When using CPU to update page table, we need to kmap all the PDs/PTs after they are allocated and that requires a TLB shot down on each CPU, which is quite heavy. Instead, we map the whole visible VRAM to a kernel address at once. Pages can be obtained from the offset. v2: move the mapping base from gmc to amdgpu_mman structure, and the implementation in amdgpu_ttm_* functions Signed-off-by:Amber Lin <Amber.Lin@amd.com> Reviewed-by:

Currently all cursor related functions are made to all pipes that are attached to a particular stream. This is not applicable to pipes that do not have cursor plane initialised like underlay. Hence this patch allows cursor related operations on a pipe only if ipp in available on that particular pipe. The check is added to set_cursor_position & set_cursor_attribute. Signed-off-by:

The drm layer expects aux->transfer() to return the payload bytes read. Currently dm_dp_aux_transfer() returns the payload size which does not gets updated during the read, hence not giving the right data for the drm layer to pars edid. This leads to the drm layer to conclude as the edid is BAD and hence some monitors/devices dont get detected properly. This patch changes the return type of dm_dp_aux_transfer() to actual bytes read during DP_AUX_NATIVE_READ & DP_AUX_I2C_READ. Signed-off-by:

otherwise there will be DMAR reading error comes out from CP since GFX is still alive and CPC's WPTR_POLL is still enabled, which would lead to DMAR read error. fix: we can hault CPG after hw_fini, but cannot halt CPC becaues KIQ stil need to be alive to let RLCV invoke, but its WPTR_POLL could be disabled.

should use bo_create_kernel instead of split to two function that create and pin the SA bo issue: before this patch, there are DMAR read error in host side when running SRIOV test, the DMAR address dropped in the range of SA bo. fix: after this cleanups of SA init and fini, above DMAR eror gone. v2: keep sa_bo's fini instead of suspend, to keep reporting error Signed-off-by:

issue: sometime GFX/MM ib test hit timeout under SRIOV env, root cause is that engine doesn't come back soon enough so the current IB test considered as timed out. fix: for SRIOV GFX IB test wait time need to be expanded a lot during SRIOV runtimei mode since it couldn't really begin before GFX engine come back. for SRIOV MM IB test it always need more time since MM scheduling is not go together with GFX engine, it is controled by h/w MM scheduler so no matter runtime or exclusive mode MM IB test always need more time. v2: use ring type instead of idx to judge Signed-off-by:

SRIOV doesn't give VF cg/pg feature so the MM's idle_work is skipped for SR-IOV v2: remove superfluous changes since idle_work is not scheduled for SR-IOV so the condition check for SR-IOV inside idle_work also can be dropped v3: drop the SRIOV check in amdgpu_vce/uvd_suspend Signed-off-by:

WB_FREE should be put after all engines's hw_fini done, otherwise the invalid wptr/rptr_addr would still be used by engines which trigger abnormal bugs. This fixes couple DMAR reading error in host side for SRIOV after guest kmd is unloaded. Signed-off-by:

two reasons to switch SCRATCH reg method to WB method: 1)Because when doing IB test we don't want to involve KIQ health status affect, and since SCRATCH register access is go through KIQ that way GFX IB test would failed due to KIQ fail. 2)acccessing SCRATCH register cost much more time than WB method because SCRATCH register access runs through KIQ which at least could begin after GPU world switch back to current Guest VF Signed-off-by:

issue: under SR-IOV sometimes the iB test will fail on gfx ring fix: with cond_exec inserted in RB the gfx engine would skip part packets if RLCV issue PREEMPT on gfx engine if gfx engine is prior to COND_EXEC packet, this is okay for regular command from UMD, but for the ib test since the whole dma format doesn't support PREEMPT so must remove the COND_EXEC from it.

the free mem space and the lower limit both include two parts: system memory and swap space. For the OOM triggered by TTM, that is the case as below: first swap space is full of swapped out pages and soon system memory also is filled up with ttm pages. and then any memory allocation request will run into OOM. to cover two cases: a. if no swap disk at all or free swap space is under swap mem limit but available system mem is bigger than sys mem limit, allow TTM allocation; b. if the available system mem is less than sys mem limit but free swap space is bigger than swap mem limit, allow TTM allocation. v2: merge two memory limit(swap and system) into one v3: keep original behavior except ttm_opt_ctx->flags with TTM_OPT_FLAG_FORCE_ALLOC v4: always set force_alloc as tx->flags & TTM_OPT_FLAG_FORCE_ALLOC v5: add an attribute for lower_mem_limit v6: set lower_mem_limit as 0 to keep original behavior Signed-off-by: -
