Add a new function drm_edid_connector_update() to replace the combination of calls drm_connector_update_edid_property() and drm_add_edid_modes(). Usually they are called in the drivers in this order, however the former needs information from the latter. Since the new drm_edid_read*() functions no longer call the connector updates directly, and the read and update are separated, we'll need this new function for the connector update. This is all in drm_edid.c simply to keep struct drm_edid opaque. v2: - Share code with drm_connector_update_edid_property() (Ville) - Add comment about override EDID handling Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/75aa3dbc8c9aa26ebbcdeacd98a466ef8d8827f4.1656494768.git.jani.nikula@intel.com
2022-06-30drm/edid: abstract debugfs override EDID set/resetJani Nikula1-1/+5
Add functions drm_edid_override_set() and drm_edid_override_reset() to support "edid_override" connector debugfs, and to hide the details about it in drm_edid.c. No functional changes at this time. Also note in the connector.override_edid flag kernel-doc that this is only supposed to be modified by the code doing debugfs EDID override handling. Currently, it is still being modified by amdgpu in create_eml_sink() and handle_edid_mgmt() for reasons unknown. This was added in commit 4562236b3bc0 ("drm/amd/dc: Add dc display driver (v2)") and later moved to amdgpu_dm.c in commit e7b07ceef2a6 ("drm/amd/display: Merge amdgpu_dm_types and amdgpu_dm").

2022-06-21drm: Config orientation property if panel provides itHsin-Yi Wang1-0/+14
Panel orientation property should be set before drm_dev_register(). Some drm driver calls drm_dev_register() in .bind(). However, most panels sets orientation property relatively late, mostly in .get_modes() callback, since this is when they are able to get the connector and binds the orientation property to it, though the value should be known when the panel is probed. In drm_bridge_connector_init(), if a bridge is a panel bridge, use it to set the connector's panel orientation property.

2022-06-03drm/dp: Add callbacks to make using DP AUX bus properly easierDouglas Anderson1-3/+31
As talked about in this patch in the kerneldoc of of_dp_aux_populate_ep_device() and also in the past in commit a1e3667a9835 ("drm/bridge: ti-sn65dsi86: Promote the AUX channel to its own sub-dev"), it can be difficult for eDP controller drivers to know when the panel has finished probing when they're using of_dp_aux_populate_ep_devices(). The ti-sn65dsi86 driver managed to solve this because it was already broken up into a bunch of sub-drivers. That means we could solve the problem there by adding a new sub-driver to get the panel. We could use the traditional -EPROBE_DEFER retry mechansim to handle the case where the panel hadn't probed yet. In parade-ps8640 we didn't really solve this. The code just expects the panel to be ready right away. While reviewing the code originally I had managed to convince myself it was fine to just expect the panel right away, but additional testing has shown that not to be the case. We could fix parade-ps8640 like we did ti-sn65dsi86 but it's pretty cumbersome (since we're not already broken into multiple drivers) and requires a bunch of boilerplate code. After discussion [1] it seems like the best solution for most people is: - Accept that there's always at most one device that will probe as a result of the DP AUX bus (it may have sub-devices, but there will be one device _directly_ probed). - When that device finishes probing, we can just have a call back. This patch implements that idea. We'll now take a callback as an argument to the populate function. To make this easier to land in pieces, we'll make wrappers for the old functions. The functions with the new name (which make it clear that we only have one child) will take the callback and the functions with the old name will temporarily wrap.

2022-05-28drm: fix EDID struct for old ARM OABI formatLinus Torvalds1-3/+3
When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc will force alignment of all structures and unions to a word boundary (see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX" option if you're a gcc person), even when the members of said structures do not want or need said alignment. This completely messes up the structure alignment of 'struct edid' on those targets, because even though all the embedded structures are marked with "__attribute__((packed))", the unions that contain them are not. This was exposed by commit f1e4c916f97f ("drm/edid: add EDID block count and size helpers"), but the bug is pre-existing. That commit just made the structure layout problem cause a build failure due to the addition of the BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH); sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data(). This legacy union alignment should probably not be used in the first place, but we can fix the layout by adding the packed attribute to the union entries even when each member is already packed and it shouldn't matter in a sane build environment. You can see this issue with a trivial test program: union { struct { char c[5]; }; struct { char d; unsigned e; } __attribute__((packed)); } a = { "1234" }; where building this with a normal "gcc -S" will result in the expected 5-byte size of said union: .type a, @object .size a, 5 but with an ARM compiler and the old ABI: arm-linux-gnu-gcc -mabi=apcs-gnu -mfloat-abi=soft -S t.c you get .type a, %object .size a, 8 instead, because even though each member of the union is packed, the union itself still gets aligned. This was reported by Sudip for the spear3xx_defconfig target.

2022-05-20drm: Document the power requirements for DP AUX transfersDouglas Anderson1-3/+13
When doing DP AUX transfers there are two actors that need to be powered in order for the DP AUX transfer to work: the DP source and the DP sink. Commit bacbab58f09d ("drm: Mention the power state requirement on side-channel operations") added some documentation saying that the DP source is required to power itself up (if needed) to do AUX transfers. However, that commit doesn't talk anything about the DP sink. For full fledged DP the sink isn't really a problem. It's expected that if an external DP monitor isn't plugged in that attempting to do AUX transfers won't work. It's also expected that if a DP monitor is plugged in (and thus asserting HPD) then AUX transfers will work. When we're looking at eDP, however, things are less obvious. Let's add some documentation about expectations. Here's what we'll say: 1. We don't expect the DP AUX transfer function to power on an eDP panel. If an eDP panel is physically connected but powered off then it makes sense for the transfer to fail. 2. We'll document that the official way to power on a panel is via the bridge chain, specifically by making sure that the panel's prepare function has been called (which is called by panel_bridge_pre_enable()). It's already specified in the kernel doc of drm_panel_prepare() that this is the way to power the panel on and also that after this call "it is possible to communicate with any integrated circuitry via a command bus." 3. We'll also document that for code running in the panel driver itself that it is legal for the panel driver to power itself up however it wants (it doesn't need to officially call drm_panel_pre_enable()) and then it can do AUX bus transfers. This is currently the way that edp-panel works when it's running atop the DP AUX bus. NOTE: there was much discussion of all of this in response to v1 [1] of this patch. A summary of that is: * With the Intel i195 driver, apparently eDP panels do get powered up. We won't forbid this but it is expected that code that wants to run on a variety of platforms should ensure that the drm_panel's prepare() function has been called. * There is at least a reasonable amount of agreement that the transfer() functions itself shouldn't be responsible for powering the panel. It's proposed that if we need the DP AUX dev nodes to be robust for eDP that the code handling the DP AUX dev nodes could handle powering the panel by ensuring that the panel's prepare() call was made. Potentially drm_dp_aux_dev_get_by_minor() could be a good place to do this. This is left as a future exercise. Until that's fixed the DP AUX dev nodes for eDP are probably best just used for debugging. * If a panel could be in PSR and DP AUX via the dev node needs to be reliable then we need to be able to pull the panel out of PSR. On i915 this is also apparently handled as part of the transfer() function.
