2023-06-04drm/msm/dpu: set DSC flush bit correctly at MDP CTL flush registerKuogee Hsieh
The CTL_FLUSH register should be programmed with the 22th bit (DSC_IDX) to flush the DSC hardware blocks, not the literal value of 22 (which corresponds to flushing VIG1, VIG2 and RGB1 instead). Changes in V12: -- split this patch out of "separate DSC flush update out of interface" Changes in V13: -- rewording the commit text Changes in V14: -- drop 'DSC" from "The DSC CTL_FLUSH register" at commit text Fixes: 77f6da90487c ("drm/msm/disp/dpu1: Add DSC support in hw_ctl") Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org> Patchwork: https://patchwork.freedesktop.org/patch/539496/ Link: https://lore.kernel.org/r/1685036458-22683-2-git-send-email-quic_khsieh@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

2023-06-01drm/msm: Use regular fbdev I/O helpersThomas Zimmermann
Use the regular fbdev helpers for framebuffer I/O instead of DRM's helpers. Msm does not use damage handling, so DRM's fbdev helpers are mere wrappers around the fbdev code. By using fbdev helpers directly within each DRM fbdev emulation, we can eventually remove DRM's wrapper functions entirely. Msm's fbdev emulation has been incomplete as it didn't implement damage handling. Partilly fix this by implementing damage handling for write and draw operation. It is still missing for mmaped pages. v4: * use initializer macros for struct fb_ops * partially support damage handling v2: * use FB_SYS_HELPERS option Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Acked-by: Sam Ravnborg <sam@ravnborg.org> Cc: Rob Clark <robdclark@gmail.com> Cc: Abhinav Kumar <quic_abhinavk@quicinc.com> Cc: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Cc: Sean Paul <sean@poorly.run> Link: https://patchwork.freedesktop.org/patch/msgid/20230530151228.22979-12-tzimmermann@suse.de

Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If the value is NULL, then the function will return 0 instead of a proper return code. Moreover dpu_hw_dsc_init() can not return NULL. Replace the IS_ERR_OR_NULL() call with IS_ERR(). This follows the commit 740828c73a36 ("drm/msm/dpu: fix error handling in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but then the commit f2803ee91a41 ("drm/msm/disp/dpu1: Add DSC support in RM") added it for DSC init.

This autorefresh disable logic in the physical command-mode encoder consumes three callbacks to the pingpong block, and will explode in unnecessary complexity when the same callbacks need to be called on the interface block instead to accommodate INTF TE support. To clean this up, move the logic into the pingpong block under a disable_autorefresh callback, replacing the aforementioned three get_autorefresh, setup_autorefresh and get_vsync_info callbacks. The same logic will have to be replicated to the interface block when it receives INTF TE support, but it is less complex than constantly switching on a "has_intf_te" boolean to choose a callback.
