From 0e0036c7d13b945260ff1ce8377eca7ea877c008 Mon Sep 17 00:00:00 2001 From: Dennis Li Date: Tue, 27 Apr 2021 22:21:03 +0800 Subject: drm/amdgpu: fix no full coverage issue for gprs initialization The wave's number per simd in aldebaran is changed to 8, so it is impossible to use old algorithm to initiate all sgprs with one threadgroup. The new algorithm firstly use three threadgroups to initiate most sgprs simultaneously and then use another threadgroup with 4 waves to cover other uninitiated sgprs. v2: Add more description about the new algorithm to clear sgprs and add some comment for shader binaries Signed-off-by: Dennis Li Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c index a2fe2dac32c1..2e6789a7dc46 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c @@ -328,7 +328,7 @@ int amdgpu_ib_pool_init(struct amdgpu_device *adev) for (i = 0; i < AMDGPU_IB_POOL_MAX; i++) { if (i == AMDGPU_IB_POOL_DIRECT) - size = PAGE_SIZE * 2; + size = PAGE_SIZE * 6; else size = AMDGPU_IB_POOL_SIZE; -- cgit v1.2.3
