2019-08-27drm/amdgpu: add dummy read for some GCVM status registersXiaojie Yuan2-0/+31
The GRBM register interface is now capable of bursting 1 cycle per register wr->wr, wr->rd much faster than previous muticycle per transaction done interface. This has caused a problem where status registers requiring HW to update have a 1 cycle delay, due to the register update having to go through GRBM. SW may operate on an incorrect value if they write a register and immediately check the corresponding status register. Registers requiring HW to clear or set fields may be delayed by 1 cycle. For example, 1. write VM_INVALIDATE_ENG0_REQ mask = 5a 2. read VM_INVALIDATE_ENG0_ACK till the ack is same as the request mask = 5a a. HW will reset VM_INVALIDATE_ENG0_ACK = 0 until invalidation is complete 3. write VM_INVALIDATE_ENG0_REQ mask = 5a 4. read VM_INVALIDATE_ENG0_ACK till the ack is same as the request mask = 5a a. First read of VM_INVALIDATE_ENG0_ACK = 5a instead of 0 b. Second read of VM_INVALIDATE_ENG0_ACK = 0 because the remote GRBM h/w register takes one extra cycle to be cleared c. In this case, SW will see a false ACK if they exit on first read Affected registers (only GC variant) | Recommended Dummy Read --------------------------------------+---------------------------- VM_INVALIDATE_ENG*_ACK | VM_INVALIDATE_ENG*_REQ VM_L2_STATUS | VM_L2_STATUS VM_L2_PROTECTION_FAULT_STATUS | VM_L2_PROTECTION_FAULT_STATUS VM_L2_PROTECTION_FAULT_ADDR_HI/LO32 | VM_L2_PROTECTION_FAULT_ADDR_HI/LO32 VM_L2_IH_LOG_BUSY | VM_L2_IH_LOG_BUSY MC_VM_L2_PERFCOUNTER_HI/LO | MC_VM_L2_PERFCOUNTER_HI/LO ATC_L2_PERFCOUNTER_HI/LO | ATC_L2_PERFCOUNTER_HI/LO ATC_L2_PERFCOUNTER2_HI/LO | ATC_L2_PERFCOUNTER2_HI/LO Signed-off-by: Xiaojie Yuan <xiaojie.yuan@amd.com> Reviewed-by: Jack Xiao <Jack.Xiao@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
