The MES FW expects us to allocate at least one page as context space to process gang and process related context data. This patch creates a joint object for the same, and calculates GPU space offsets of these spaces. V1: Addressed review comments on RFC patch: Alex: Make this function IP specific V2: Addressed review comments from Christian - Allocate only one object for total FW space, and calculate offsets for each of these objects. V3: Integration with doorbell manager V4: Review comments: - Remove shadow from FW space list from cover letter (Alex) - Alignment of macro (Luben) V5: Merged patches 5 and 6 into this single patch Addressed review comments: - Use lower_32_bits instead of mask (Christian) - gfx_v11_0 instead of gfx_v11 in function names (Alex) - Shadow and GDS objects are now coming from userspace (Christian, Alex) V6: - Add a comment to replace amdgpu_bo_create_kernel() with amdgpu_bo_create() during fw_ctx object creation (Christian). - Move proc_ctx_gpu_addr, gang_ctx_gpu_addr and fw_ctx_gpu_addr out of generic queue structure and make it gen11 specific (Alex). V7: - Using helper function to create/destroy userqueue objects. - Removed FW object space allocation. V8: - Updating FW object address from user values. V9: - uppdated function name from gfx_v11_* to mes_v11_* V10: - making this patch independent of IP based changes, moving any GFX object related changes in GFX specific patch (Alex) Cc: Alex Deucher <alexander.deucher@xxxxxxx> Cc: Christian Koenig <christian.koenig@xxxxxxx> Acked-by: Christian Koenig <christian.koenig@xxxxxxx> Signed-off-by: Shashank Sharma <shashank.sharma@xxxxxxx> Signed-off-by: Arvind Yadav <arvind.yadav@xxxxxxx> --- .../gpu/drm/amd/amdgpu/mes_v11_0_userqueue.c | 33 +++++++++++++++++++ .../gpu/drm/amd/include/amdgpu_userqueue.h | 1 + 2 files changed, 34 insertions(+) diff --git a/drivers/gpu/drm/amd/amdgpu/mes_v11_0_userqueue.c b/drivers/gpu/drm/amd/amdgpu/mes_v11_0_userqueue.c index 75d7c58418c8..58cfc956cddd 100644 --- a/drivers/gpu/drm/amd/amdgpu/mes_v11_0_userqueue.c +++ b/drivers/gpu/drm/amd/amdgpu/mes_v11_0_userqueue.c @@ -27,6 +27,31 @@ #include "mes_v11_0.h" #include "mes_v11_0_userqueue.h" +#define AMDGPU_USERQ_PROC_CTX_SZ PAGE_SIZE +#define AMDGPU_USERQ_GANG_CTX_SZ PAGE_SIZE + +static int mes_v11_0_userq_create_ctx_space(struct amdgpu_userq_mgr *uq_mgr, + struct amdgpu_usermode_queue *queue, + struct drm_amdgpu_userq_in *mqd_user) +{ + struct amdgpu_userq_obj *ctx = &queue->fw_obj; + int r, size; + + /* + * The FW expects at least one page space allocated for + * process ctx and gang ctx each.
