2023-10-26drm/amdgpu: move buffer funcs setting up a levelAlex Deucher
Rather than doing this in the IP code for the SDMA paging engine, move it up to the core device level init level. This should fix the scheduler init ordering. v2: drop extra parens v3: drop SDMA helpers v4: Added a Fixes tag because amdgpu dereferences an uninitialized scheduler without this patch, and this patch fixes this.

2023-09-28drm/amd: Move microcode init from sw_init to early_init for SDMA v5.2Mario Limonciello
As part of IP discovery early_init is run for all HW IP blocks. During this phase all firmware is supposed to be identified that may be missing so that the driver can avoid releasing resources used by the EFI framebuffer or simpledrm until the last possible moment.

2022-10-10drm/amdgpu: Fix SDMA engine resume issue under SRIOVBokun Zhang
- Under SRIOV, SDMA engine is shared between VFs. Therefore, we will not stop SDMA during hw_fini. This is not an issue with normal dirver loading and unloading. - However, when we put the SDMA engine to suspend state and resume it, the issue starts to show up. Something could attempt to use that SDMA engine to clear or move memory before the engine is initialized since the DRM entity is still there. - Therefore, we will call sdma_v5_2_enable(false) during hw_fini, and if we are under SRIOV, we will call sdma_v5_2_enable(true) afterwards to allow other VFs to use SDMA. This way, the DRM entity of SDMA engine is emptied and it will follow the flow of resume code path.

This patch fixes the issue where the driver miscomputes the 64-bit values of the wptr of the SDMA doorbell when initializing the hardware. SDMA engines v4 and later on have full 64-bit registers for wptr thus they should be set properly.
