drm/amdgpu: try again kiq access if not in IRQ(v4)

2018-03-01T17:04:17Z

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: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: move static CSA address to top of address space v2

2018-02-19T19:18:48Z

Move the CSA area to the top of the VA space to avoid clashing with HMM/ATC in the lower range on GFX9. v2: wrong sign noticed by Roger, rebase on CSA_VADDR cleanup, handle VA hole on GFX9 as well. Signed-off-by: Christian König Acked-by: Alex Deucher Acked-by: Monk Liu Signed-off-by: Alex Deucher

drm/amdgpu/virt: add wait_reset virt ops

2017-12-04T21:33:13Z

Driver can use this interface to check if there's a function level reset done in hypervisor. It's helpful when IRQ handler for reset is not ready, or special handling is required. Acked-by: Alex Deucher Reviewed-by: Monk Liu Signed-off-by: pding Signed-off-by: Alex Deucher

This lock is used during register accessing in SRIOV guest. The register accessing could happen both in irq enabled and irq disabled cases. Always use irq-safe lock. Signed-off-by: Pixel Ding Reviewed-by: Christian König Signed-off-by: Alex Deucher
