drm/amdgpu: create MES-V11 usermode queue for GFX A Memory queue descriptor (MQD) of a userqueue defines it in the hw's context. As MQD format can vary between different graphics IPs, we need gfx GEN specific handlers to create MQDs. This patch: - Adds a new file which will be used for MES based userqueue functions targeting GFX and SDMA IP. - Introduces MQD handler functions for the usermode queues. V1: Worked on review comments from Alex: - Make MQD functions GEN and IP specific V2: Worked on review comments from Alex: - Reuse the existing adev->mqd[ip] for MQD creation - Formatting and arrangement of code V3: - Integration with doorbell manager V4: Review comments addressed: - Do not create a new file for userq, reuse gfx_v11_0.c (Alex) - Align name of structure members (Luben) - Don't break up the Cc tag list and the Sob tag list in commit message (Luben) V5: - No need to reserve the bo for MQD (Christian). - Some more changes to support IP specific MQD creation. V6: - Add a comment reminding us to replace the amdgpu_bo_create_kernel() calls while creating MQD object to amdgpu_bo_create() once eviction fences are ready (Christian). V7: - Re-arrange userqueue functions in adev instead of uq_mgr (Alex) - Use memdup_user instead of copy_from_user (Christian) V9: - Moved userqueue code from gfx_v11_0.c to new file mes_v11_0.c so that it can be reused for SDMA userqueues as well (Shashank, Alex) V10: Addressed review comments from Alex - Making this patch independent of IP engine(GFX/SDMA/Compute) and specific to MES V11 only, using the generic MQD structure. - Splitting a spearate patch to enabling GFX support from here. - Verify mqd va address to be non-NULL. - Add a separate header file.
