Indeed the sha1 info is useless, it's based on v5.15-rc2 on top of "HACK: drm/omap: increase DSS5 max tv pclk to 192MHz" in order to validate on 2k monitors. I'm personally fine with removing the HACK from that, and applying it too. I used the patch for a long time without any issues. However, I never found anyone to confirm that 192MHz is fine (or that it's not fine). Too old HW for finding HW engineers to look at it =). Tomi

Indeed the sha1 info is useless, it's based on v5.15-rc2 on top of "HACK: drm/omap: increase DSS5 max tv pclk to 192MHz" in order to validate on 2k monitors. My bad, I thought it would apply based on this patch, I'll rebase on v5.15-rc2 for v6. Thanks for the review, Neil > > Tomi

Gentle ping, who is supposed reviewing those patches ? I think that would be me. I'll try to find time in the nearby future to do the review. Tomi

[PATCH v5 0/8] drm/omap: Add virtual-planes support
This patchset is the follow-up the v4 patchset from Benoit Parrot at [1]. This patch series adds virtual-plane support to omapdrm driver to allow the use of display wider than 2048 pixels. In order to do so we introduce the concept of hw_overlay which can then be dynamically allocated to a plane. When the requested output width exceed what be supported by one overlay a second is then allocated if possible to handle display wider then 2048. This series replaces an earlier series which was DT based and using statically allocated resources. This implementation is inspired from the work done in msm/disp/mdp5 driver. Changes since v4 at [1]: - rebased on v5.15-rc2 - adapted to drm_atomic_get_new/old_plane_state() - tested on Beagle-x15 - checked for non-regression on Beagle-x15 - removed unused "state" variable in omap_global_state [1] https://lore.kernel.org/all/20181012201703.29065-1-bpar...@ti.com/ Benoit Parrot (8): drm/omap: Add ability to check if requested plane modes can be supported drm/omap: Add ovl checking funcs to dispc_ops drm/omap: introduce omap_hw_overlay drm/omap: omap_plane: subclass drm_plane_state drm/omap: Add global state as a private atomic object drm/omap: dynamically assign hw overlays to planes drm/omap: add plane_atomic_print_state support drm/omap: Add a 'right overlay' to plane state drivers/gpu/drm/omapdrm/Makefile | 1 + drivers/gpu/drm/omapdrm/dss/dispc.c| 31 +- drivers/gpu/drm/omapdrm/dss/dss.h | 5 + drivers/gpu/drm/omapdrm/omap_drv.c | 189 - drivers/gpu/drm/omapdrm/omap_drv.h | 28 ++ drivers/gpu/drm/omapdrm/omap_fb.c | 33 ++- drivers/gpu/drm/omapdrm/omap_fb.h | 4 +- drivers/gpu/drm/omapdrm/omap_overlay.c | 254 + drivers/gpu/drm/omapdrm/omap_overlay.h | 41 +++ drivers/gpu/drm/omapdrm/omap_plane.c | 375 + drivers/gpu/drm/omapdrm/omap_plane.h | 1 + 11 files changed, 903 insertions(+), 59 deletions(-) create mode 100644 drivers/gpu/drm/omapdrm/omap_overlay.c create mode 100644 drivers/gpu/drm/omapdrm/omap_overlay.h -- 2.25.1
