| Series | [RFC] drm/msm/disp/dpu1: add support for inline rotation in dpu driver | expand |
Hi, Something is wrong with the threading, since this patch does not contain In-Reply-To header pointing to the cover letter? Could you please correct that? Using git-send-email --compose would allow you to write properly threaded cover letter. On 03/07/2021 14:32, Kalyan Thota wrote: > Add inline rotation support in dpu driver. This change adds > rotation config for SC7280 target. After spending some time reading display techpack, I think I'll ask you to add some summary to the patch summary, describing some bits and pieces. For example: - Some DPU versions support inline rot90. It is supported only for limited amount of UBWC formats. - There are two versions of inline rotators, v1 (present on sm8250 and sm7250) and v2 (sc7280). These versions differ in the list of supported formats and in the scaler possibilities. - rot90 options are common to the rotation block version and do not depend on the SoC. > > Change-Id: I15861dc03422274ffd823fc0fc2c1e47909bb22c Please remove this > Signed-off-by: Kalyan Thota <kalyan_t@codeaurora.org> > --- > drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 47 +++++++++---- > drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 20 ++++++ > drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 93 ++++++++++++++++++++------ > drivers/gpu/drm/msm/disp/dpu1/dpu_plane.h | 2 + > 4 files changed, 128 insertions(+), 34 deletions(-) > > diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c > index d01c4c9..45e4e56 100644 > --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c > +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c > @@ -25,6 +25,9 @@ > #define VIG_SM8250_MASK \ > (VIG_MASK | BIT(DPU_SSPP_QOS_8LVL) | BIT(DPU_SSPP_SCALER_QSEED3LITE)) > > +#define VIG_SC7280_MASK \ > + (VIG_SC7180_MASK | BIT(DPU_SSPP_INLINE_ROTATION)) > + > #define DMA_SDM845_MASK \ > (BIT(DPU_SSPP_SRC) | BIT(DPU_SSPP_QOS) | BIT(DPU_SSPP_QOS_8LVL) |\ > BIT(DPU_SSPP_TS_PREFILL) | BIT(DPU_SSPP_TS_PREFILL_REC1) |\ > @@ -102,6 +105,8 @@ > #define MAX_DOWNSCALE_RATIO 4 > #define SSPP_UNITY_SCALE 1 > > +#define INLINE_ROTATOR_V2 2 > + > #define STRCAT(X, Y) (X Y) > > static const uint32_t plane_formats[] = { > @@ -177,6 +182,11 @@ static const uint32_t plane_formats_yuv[] = { > DRM_FORMAT_YVU420, > }; > > +static const uint32_t rotation_formats[] = { rotation_v2_formats? > + DRM_FORMAT_NV12, > + /* TODO add formats after validation */ > +}; > + > /************************************************************* > * DPU sub blocks config > *************************************************************/ > @@ -465,7 +475,16 @@ static const struct dpu_ctl_cfg sc7280_ctl[] = { > > /* SSPP common configuration */ > > -#define _VIG_SBLK(num, sdma_pri, qseed_ver) \ > +static const struct dpu_rotation_cfg dpu_rot_cfg = { dpu_rot_cfg is a bit too broad. dpu_rot_cfg_v2 seem to be more appropriate. > + .version = INLINE_ROTATOR_V2, There are no check on the version, so you can drop this field. > + .rot_maxdwnscale_ratio_num = 1, > + .rot_maxdwnscale_ratio_dem = 1, These don't seem to be used in your patch. Was the intent to avoid all the pre-downscale and downscale options? If so I'd suggest just enforcing the scale factor to 1 for now in the rot90 checking code. From reading the code I had the impression that for v2 downscaling up to 4:1 should be supported, so there is no need for special handling (VIG_SBLK already declared downscaling up to 4:1). V1 is different and will need limiting to 11:5.
