From f091fa777b24c189523db1ea626434ad6ff29799 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 18 Feb 2025 12:07:48 -0500 Subject: drm/amdgpu/gfx: add generic handling for disable_kq Add proper checks for disable_kq functionality in gfx helper functions. Add special logic for families that require the clear state setup. v2: use ring count as per Felix suggestion v3: fix num_gfx_rings handling in amdgpu_gfx_graphics_queue_acquire() v4: fix error code (Alex) Reviewed-by: Prike Liang Reviewed-by: Sunil Khatri Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c index f64675b2ab75..0f84e5afd564 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c @@ -259,8 +259,9 @@ void amdgpu_gfx_graphics_queue_acquire(struct amdgpu_device *adev) } /* update the number of active graphics rings */ - adev->gfx.num_gfx_rings = - bitmap_weight(adev->gfx.me.queue_bitmap, AMDGPU_MAX_GFX_QUEUES); + if (adev->gfx.num_gfx_rings) + adev->gfx.num_gfx_rings = + bitmap_weight(adev->gfx.me.queue_bitmap, AMDGPU_MAX_GFX_QUEUES); } static int amdgpu_gfx_kiq_acquire(struct amdgpu_device *adev, @@ -1545,6 +1546,9 @@ static ssize_t amdgpu_gfx_set_run_cleaner_shader(struct device *dev, if (adev->in_suspend && !adev->in_runpm) return -EPERM; + if (adev->gfx.disable_kq) + return -EPERM; + ret = kstrtol(buf, 0, &value); if (ret) -- cgit v1.2.3
