2025-04-08drm/amdgpu: use "irq" in place of "interrupt" in DCE6/8 as in DCE10/11Alexandre Demers1-6/+6
"interrupt" becomes "irq" in: dce_vX_0_set_hpd_interrupt_state() dce_vX_0_set_crtc_interrupt_state() dce_vX_0_set_pageflip_interrupt_state() It is easier when going through the code to just change the DCE number in the functions' name to find and compare them across DCE versions. Also, it standardizes function mapping inside a given structure where .set and .process are both set to functions with a "_irq" suffix.

In DCE6, DCE8, DCE10, DCE11, "hdp" is replaced by "hpd" and replace "type" by "hpd" for a uniform parameter naming usage across DCEs.

By replacing VGA_VSTATUS_CNTL by VGA_RENDER_CONTROL__VGA_VSTATUS_CNTL_MASK, we also need to fix its usage in GMC6.

2023-01-05drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interruptxurui1-3/+3
HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.

2022-01-31drm: introduce fb_modifiers_not_supported flag in mode_configTomohito Esaki1-0/+1
If only linear modifier is advertised, since there are many drivers that only linear supported, the DRM core should handle this rather than open-coding in every driver. However, there are legacy drivers such as radeon that do not support modifiers but infer the actual layout of the underlying buffer. Therefore, a new flag fb_modifiers_not_supported is introduced for these legacy drivers, and allow_fb_modifiers is replaced with this new flag. v3: - change the order as follows: 1. add fb_modifiers_not_supported flag 2. add default modifiers 3. remove allow_fb_modifiers flag - add a conditional disable in amdgpu_dm_plane_init() v4: - modify kernel docs v5: - modify kernel docs Signed-off-by: Tomohito Esaki <etom@igel.co.jp> Acked-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220128060836.11216-2-etom@igel.co.jp
