From: Tong Liu01 Date: Thu, 17 Nov 2022 10:18:58 +0000 (+0800) Subject: drm/amdgpu: add drv_vram_usage_va for virt data exchange X-Git-Tag: v6.6.7~3824^2~4^2~63 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d96ced7600e02ac1efb03a21af529fd9a95e3c6;p=platform%2Fkernel%2Flinux-starfive.git drm/amdgpu: add drv_vram_usage_va for virt data exchange For vram_usagebyfirmware_v2_2, fw_vram_reserve is not used. So fw_vram_usage_va is NULL, and cannot do virt data exchange anymore. Should add drv_vram_usage_va to do virt data exchange in vram_usagebyfirmware_v2_2 case. And refine some code style checks in pre add vram reservation logic patch Signed-off-by: Tong Liu01 Acked-by: Luben Tuikov Signed-off-by: Alex Deucher --- diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_atomfirmware.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_atomfirmware.c index 9b97fa3..e40df72c 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_atomfirmware.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_atomfirmware.c @@ -104,7 +104,7 @@ void amdgpu_atomfirmware_scratch_regs_init(struct amdgpu_device *adev) static int amdgpu_atomfirmware_allocate_fb_v2_1(struct amdgpu_device *adev, struct vram_usagebyfirmware_v2_1 *fw_usage, int *usage_bytes) { - uint32_t start_addr, fw_size, drv_size;
