2020-04-01	drm/amdgpu: use static mmio offset for NV mailbox	Monk Liu	1	-30/+22
	what: with the new "req_init_data" handshake we need to use mailbox before do IP discovery, so in mxgpu_nv.c file the original SOC15_REG method won'twork because that depends on IP discovery complete first. how: so the solution is to always use static MMIO offset for NV+ mailbox registers. HW team confirm us all MAILBOX registers will be at the same offset for all ASICs, no IP discovery needed for those registers Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Emily Deng <Emily.Deng@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-04-01	drm/amdgpu: introduce new request and its function	Monk Liu	1	-8/+40
	1) modify xgpu_nv_send_access_requests to support new idh request 2) introduce new function: req_gpu_init_data() which is used to notify host to prepare vbios/ip-discovery/pfvf exchange Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Emily Deng <Emily.Deng@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-04-01	drm/amdgpu: cleanup idh event/req for NV headers	Monk Liu	1	-1/+0
	1) drop the headers from AI in mxgpu_nv.c, should refer to mxgpu_nv.h 2) the IDH_EVENT_MAX is not used and not aligned with host side so drop it 3) the IDH_TEXT_MESSAG was provided in host but not defined in guest Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Emily Deng <Emily.Deng@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2019-12-18	drm/amdgpu: fix double gpu_recovery for NV of SRIOV	Monk Liu	1	-1/+5
	issues: gpu_recover() is re-entered by the mailbox interrupt handler mxgpu_nv.c fix: we need to bypass the gpu_recover() invoke in mailbox interrupt as long as the timeout is not infinite (thus the TDR will be triggered automatically after time out, no need to invoke gpu_recover() through mailbox interrupt.
