2021-08-10drm/amdgpu: handle VCN instances when harvesting (v2)Alex Deucher1-3/+9
There may be multiple instances and only one is harvested. v2: fix typo in commit message Fixes: 83a0b8639185 ("drm/amdgpu: add judgement when add ip blocks (v2)") Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1673 Reviewed-by: Guchun Chen <[email protected]> Reviewed-by: James Zhu <[email protected]> Signed-off-by: Alex Deucher <[email protected]> Cc: [email protected]
2021-06-18drm/amd/amdgpu: Use IP discovery data to determine VCN enablement instead of ↵Bokun Zhang1-0/+8
MMSCH In the past, we use MMSCH to determine whether a VCN is enabled or not. This is not reliable since after a FLR, MMSCH may report junk data. It is better to use IP discovery data.

2021-06-11drm/amd/amdgpu: add instance_number check in amdgpu_discovery_get_ip_versionPeng Ju Zhou1-2/+2
The original code returns IP version of instantce_0 for every IP. This implementation may be correct for most of IPs. However, for certain IP block (VCN for example), it may have 2 instances and both of them have the same hw_id, BUT they have different revision number (0 and 1). In this case, the original amdgpu_discovery_get_ip_version cannot correct reflects the result and returns false information Signed-off-by: Bokun Zhang <[email protected]> Signed-off-by: Peng Ju Zhou <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2020-04-01drm/amdgpu: adjust sequence of ip_discovery init and timeout_settingMonk Liu1-4/+6
what: 1)move timtout setting before ip_early_init to reduce exclusive mode cost for SRIOV 2)move ip_discovery_init() to inside of amdgpu_discovery_reg_base_init() it is a prepare for the later upcoming patches. why: in later upcoming patches we would use a new mailbox event -- "req_gpu_init_data", which is a callback hooked in adev->virt.ops and this callback send a new event "REQ_GPU_INIT_DAT" to host to notify host to do some preparation like "IP discovery/vbios on the VF FB" and this callback must be: A) invoked after set_ip_block() because virt.ops is configured during set_ip_block() B) invoked before ip_discovery_init() becausen ip_discovery_init() need host side prepares everything in VF FB first. current place of ip_discovery_init() is before we can invoke callback of adev->virt.ops, thus we must move ip_discovery_init() to a place after the adev->virt.ops all settle done, and the perfect place is in amdgpu_discovery_reg_base_init() Signed-off-by: Monk Liu <[email protected]> Reviewed-by: Emily Deng <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
