(was: Rate-limit shadow-FB-to-console-update to screen refresh) Implement support for VBLANK events in mgag200. Patches 1 to 5 prepare mgag200's modesetting code by renaming or adding variables for various hardware fields. This makes the code more readable and aligns it with the programming manuals for Matrox hardware. Patch 6 implements support for VBLANK events. The patch has been reviewed before at [1]. That old patchset never found its way into the kernel, but the VBLANK support is still useful. Patch 7 adds support for VBLANK timestamps. v4: - split off the patchset from an earlier series [1] [1] https://patchwork.freedesktop.org/series/66442/ Thomas Zimmermann (7): drm/mgag200: Use hexadecimal register indeces drm/mgag200: Align register field names with documentation drm/mgag200: Use adjusted mode values for CRTCs drm/mgag200: Add dedicated variables for blanking fields drm/mgag200: Add dedicted variable for <linecomp> field drm/mgag200: Add vblank support drm/mgag200: Implement struct drm_crtc_funcs.get_vblank_timestamp drivers/gpu/drm/mgag200/mgag200_drv.c | 47 ++++++ drivers/gpu/drm/mgag200/mgag200_drv.h | 14 +- drivers/gpu/drm/mgag200/mgag200_g200.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200eh.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200eh3.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200er.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200ev.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200ew3.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200se.c | 5 + drivers/gpu/drm/mgag200/mgag200_g200wb.c | 5 + drivers/gpu/drm/mgag200/mgag200_mode.c | 169 ++++++++++++++++------ drivers/gpu/drm/mgag200/mgag200_reg.h | 7 + 12 files changed, 232 insertions(+), 45 deletions(-) -- 2.45.2
