2018-01-18drm/i915: Check for downstream topology errorsRamalingam C1-0/+2
HDCP compliant Repeaters can support max of 127 devices and max depth of 7 for downstream topology. If these max limits are exceeded, repeater will set the topology error flags MAX_CASCADE_EXCEEDED and/or MAX_DEVS_EXCEEDED in Bstatus followed by asserting READY/CP_IRQ for HDCP transmitter. This patch check for these error flags as soon as READY bit is asserted.

After some discussion and failed patch sets trying to convey the right timing information between the display engine and a bridge using the connector, I try instead to use an optional timing information container in the bridge itself, so that display engines can retrieve it from any bridge and use it to determine how to drive outputs.

2018-01-08drm: Add Content Protection propertySean Paul1-0/+16
This patch adds a new optional connector property to allow userspace to enable protection over the content it is displaying. This will typically be implemented by the driver using HDCP. The property is a tri-state with the following values: - OFF: Self explanatory, no content protection - DESIRED: Userspace requests that the driver enable protection - ENABLED: Once the driver has authenticated the link, it sets this value The driver is responsible for downgrading ENABLED to DESIRED if the link becomes unprotected. The driver should also maintain the desiredness of protection across hotplug/dpms/suspend. If this looks familiar, I posted [1] this 3 years ago. We have been using this in ChromeOS across exynos, mediatek, and rockchip over that time. Changes in v2: - Pimp kerneldoc for content_protection_property (Daniel) - Drop sysfs attribute Changes in v3: - None Changes in v4: - Changed kerneldoc to recommend userspace polling (Daniel) - Changed kerneldoc to briefly describe how to attach the property (Daniel) Changes in v5: - checkpatch whitespace noise - Change DRM_MODE_CONTENT_PROTECTION_OFF to DRM_MODE_CONTENT_PROTECTION_UNDESIRED Changes in v6: - None Reviewed-by: Daniel Vetter <[email protected]> Signed-off-by: Sean Paul <[email protected]> [1] https://lists.freedesktop.org/archives/dri-devel/2014-December/073336.html Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

DK put some nice docs into the commit introducing driver private state, but in the git history alone it'll be lost. Also, since Ville remove the void* usage it's a good opportunity to give the driver private stuff some tlc on the doc front. Finally try to explain why the "let's just subclass drm_atomic_state" approach wasn't the greatest, and annotate all those functions as deprecated in favour of more standardized driver private states. Also note where we could/should extend driver private states going forward (atm neither locking nor synchronization is handled in core/helpers, which isn't really all that great). v2: Spelling and phrasing improvements (Alex, DK).

2017-12-15drm/print: Unconfuse kerneldocDaniel Vetter1-1/+1
It thinks we want to document the __printf(2,0) annotion. Not sure we want to teach it about all possible gcc-only flags, hence why I opted for the cheap trick of just moving it ahead of the kerneldoc. This is only a problem for static inline functions, since for non-inline function the kerneldoc is in the .c file, but the special annotations are all in the header. Cc'ing kernel-doc maintainers as fyi.

2017-12-13drm: rework delayed connector cleanup in connector_iterDaniel Vetter2-5/+23
PROBE_DEFER also uses system_wq to reprobe drivers, which means when that again fails, and we try to flush the overall system_wq (to get all the delayed connectore cleanup work_struct completed), we deadlock. Fix this by using just a single cleanup work, so that we can only flush that one and don't block on anything else. That means a free list plus locking, a standard pattern. v2: - Correctly free connectors only on last ref. Oops (Chris). - use llist_head/node (Chris). v3 - Add init_llist_head (Chris).

2017-12-13drm: Update edid-derived drm_display_info fields at edid property set [v2]Keith Packard1-0/+2
There are a set of values in the drm_display_info structure for each connector which hold information derived from EDID. These are computed in drm_add_display_info. Before this patch, that was only called in drm_add_edid_modes. This meant that they were only set when EDID was present and never reset when EDID was not, as happened when the display was disconnected. One of these fields, non_desktop, is used from drm_mode_connector_update_edid_property, the function responsible for assigning the new edid value to the application-visible property. Various drivers call these two functions (drm_add_edid_modes and drm_mode_connector_update_edid_property) in different orders. This means that even when EDID is present, the drm_display_info fields may not have been computed at the time that drm_mode_connector_update_edid_property used the non_desktop value to set the non_desktop property. I've added a public function (drm_reset_display_info) that resets the drm_display_info field values to default values and then made the drm_add_display_info function public. These two functions are now called directly from drm_mode_connector_update_edid_property so that the drm_display_info fields are always computed from the current EDID information before being used in that function. This means that the drm_display_info values are often computed twice, once when the EDID property it set and a second time when EDID is used to compute modes for the device. The alternative would be to uniformly ensure that the values were computed once before being used, which would require that all drivers reliably invoke the two paths in the same order. The computation is inexpensive enough that it seems more maintainable in the long term to simply compute them in both paths. The API to drm_add_display_info has been changed so that it no longer takes the set of edid-based quirks as a parameter. Rather, it now computes those quirks itself and returns them for further use by drm_add_edid_modes. This patch also includes a number of 'const' additions caused by drm_mode_connector_update_edid_property taking a 'const struct edid *' parameter and wanting to pass that along to drm_add_display_info. v2: after review by Daniel Vetter <[email protected]> Removed EXPORT_SYMBOL_GPL for drm_reset_display_info and drm_add_display_info. Added FIXME in drm_mode_connector_update_edid_property about potentially merging that with drm_add_edid_modes to avoid the need for two driver calls.
