[PATCH v2 0/5] drm/connector: make mode_valid() callback accept const mode pointer
While working on the generic mode_valid() implementation for the HDMI
Connector framework I noticed that unlike other DRM objects
drm_connector accepts non-const pointer to struct drm_display_mode,
while obviously mode_valid() isn't expected to modify the argument.
Mass-change the DRM framework code to pass const argument to that
callback.
The series has been compile-tested with defconfig for x86-64, arm and
arm64.
Note: yes, I understand that this change might be hard to review and
merge. The only viable option that I foresee is to add new callback,
having the const argument and migrate drivers into using it one by one.

Changes in v2:
- Rebased on top of linux-next
- Replaced 'accept const argument' with 'take a const arugment'
(Laurent)
- Link to v1:

[PATCH v2 2/5] drm/amdgpu: don't change mode in amdgpu_dm_connector_mode_valid()
Make amdgpu_dm_connector_mode_valid() duplicate the mode during the

converting the mode_valid() callback of drm_connector to take a const
struct drm_display_mode argument.

[PATCH v2 0/5] drm/connector: make mode_valid() callback accept const mode pointer

Should it be merged as is (possibly requiring more R-B's)? Or should I rework it adding something like .mode_valid_new() callback which takes const argument?> > Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov at linaro.org> > --- > Changes in v2: > - Rebased on top of linux-next > - Replaced 'accept const argument' with 'take a const arugment' > (Laurent) > - Link to v1: https://lore.kernel.org/r/20241115-drm-connector-mode-valid-const-v1-0-b1b523156f71 at linaro.org > > --- > Dmitry Baryshkov (5): > drm/encoder_slave: make mode_valid accept const struct drm_display_mode > drm/amdgpu: don't change mode in amdgpu_dm_connector_mode_valid() > drm/sti: hda: pass const struct drm_display_mode* to hda_get_mode_idx() > drm/connector: make mode_valid_ctx take a const struct drm_display_mode > drm/connector: make mode_valid take a const struct drm_display_mode > > drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c | 8 ++++---- > drivers/gpu/drm/amd/amdgpu/atombios_dp.c | 2 +- > drivers/gpu/drm/amd/amdgpu/atombios_dp.h | 2 +- > drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 12 +++++++++--- > drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 2 +- > drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c | 2 +- > drivers/gpu/drm/arm/malidp_mw.c | 2 +- > drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 2 +- > drivers/gpu/drm/bridge/cadence/cdns-mhdp8546-core.c | 2 +- > drivers/gpu/drm/bridge/megachips-stdpxxxx-ge-b850v3-fw.c | 7 ------- > drivers/gpu/drm/display/drm_bridge_connector.c | 2 +- > drivers/gpu/drm/display/drm_hdmi_state_helper.c | 2 +- > drivers/gpu/drm/drm_crtc_helper_internal.h | 2 +- > drivers/gpu/drm/drm_probe_helper.c | 2 +- > drivers/gpu/drm/exynos/exynos_hdmi.c | 2 +- > drivers/gpu/drm/fsl-dcu/fsl_dcu_drm_rgb.c | 2 +- > drivers/gpu/drm/gma500/cdv_intel_crt.c | 2 +- > drivers/gpu/drm/gma500/cdv_intel_dp.c | 2 +- > drivers/gpu/drm/gma500/cdv_intel_hdmi.c | 2 +- > drivers/gpu/drm/gma500/cdv_intel_lvds.c | 2 +- > drivers/gpu/drm/gma500/oaktrail_hdmi.c | 2 +- > drivers/gpu/drm/gma500/psb_intel_drv.h | 2 +- > drivers/gpu/drm/gma500/psb_intel_lvds.c | 2 +- > drivers/gpu/drm/gma500/psb_intel_sdvo.c | 2 +- > drivers/gpu/drm/i2c/ch7006_drv.c | 2 +- > drivers/gpu/drm/i2c/sil164_drv.c | 2 +- > drivers/gpu/drm/i915/display/dvo_ch7017.c | 2 +- > drivers/gpu/drm/i915/display/dvo_ch7xxx.c | 2 +- > drivers/gpu/drm/i915/display/dvo_ivch.c | 2 +- > drivers/gpu/drm/i915/display/dvo_ns2501.c | 2 +- > drivers/gpu/drm/i915/display/dvo_sil164.c | 2 +- > drivers/gpu/drm/i915/display/dvo_tfp410.c | 2 +- > drivers/gpu/drm/i915/display/icl_dsi.c | 2 +- > drivers/gpu/drm/i915/display/intel_crt.c | 2 +- > drivers/gpu/drm/i915/display/intel_dp.c | 2 +- > drivers/gpu/drm/i915/display/intel_dp_mst.c | 2 +- > drivers/gpu/drm/i915/display/intel_dsi.c | 2 +- > drivers/gpu/drm/i915/display/intel_dsi.h | 2 +- > drivers/gpu/drm/i915/display/intel_dvo.c | 2 +- > drivers/gpu/drm/i915/display/intel_dvo_dev.h | 2 +- > drivers/gpu/drm/i915/display/intel_hdmi.c | 2 +- > drivers/gpu/drm/i915/display/intel_lvds.c | 2 +- > drivers/gpu/drm/i915/display/intel_sdvo.c | 2 +- > drivers/gpu/drm/i915/display/intel_tv.c | 2 +- > drivers/gpu/drm/i915/display/vlv_dsi.c | 2 +- > drivers/gpu/drm/imx/ipuv3/imx-tve.c | 2 +- > drivers/gpu/drm/msm/disp/mdp4/mdp4_lvds_connector.c | 2 +- > drivers/gpu/drm/nouveau/dispnv04/tvnv17.c | 2 +- > drivers/gpu/drm/nouveau/dispnv50/disp.c | 2 +- > drivers/gpu/drm/nouveau/nouveau_connector.c | 2 +- > drivers/gpu/drm/qxl/qxl_display.c | 2 +- > drivers/gpu/drm/radeon/atombios_dp.c | 2 +- > drivers/gpu/drm/radeon/radeon_connectors.c | 10 +++++----- > drivers/gpu/drm/radeon/radeon_mode.h | 2 +- > drivers/gpu/drm/rockchip/cdn-dp-core.c | 2 +- > drivers/gpu/drm/rockchip/inno_hdmi.c | 4 ++-- > drivers/gpu/drm/rockchip/rk3066_hdmi.c | 2 +- > drivers/gpu/drm/sti/sti_dvo.c | 2 +- > drivers/gpu/drm/sti/sti_hda.c | 12 ++++++------ > drivers/gpu/drm/sti/sti_hdmi.c | 2 +- > drivers/gpu/drm/tegra/dsi.c | 2 +- > drivers/gpu/drm/tegra/hdmi.c | 2 +- > drivers/gpu/drm/tegra/sor.c | 2 +- > drivers/gpu/drm/vc4/vc4_txp.c | 2 +- > drivers/gpu/drm/virtio/virtgpu_display.c | 2 +- > drivers/gpu/drm/vmwgfx/vmwgfx_kms.c | 2 +- > drivers/gpu/drm/vmwgfx/vmwgfx_kms.h | 2 +- > drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c | 2 +- > include/drm/display/drm_hdmi_state_helper.h | 2 +- > include/drm/drm_encoder_slave.h | 2 +- > include/drm/drm_modeset_helper_vtables.h | 4 ++-- > 71 files changed, 92 insertions(+), 93 deletions(-) > --- > base-commit: 4176cf5c5651c33769de83bb61b0287f4ec7719f > change-id: 20241115-drm-connector-mode-valid-const-ae3db0ef6cb7 > > Best regards, > -- > Dmitry Baryshkov <dmitry.baryshkov at linaro.org> >-- With best wishes Dmitry
