Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to intel_fbdev_setup() after i915 has registered its DRM device. Just like similar code in other drivers, i915 fbdev emulation now acts like a regular DRM client. Do the same for xe. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_client_dev_unregister() releases all in-kernel clients automatically. No further action is required within i915. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup. Do the same for xe and remove its call to intel_fbdev_fini(). v8: - setup client in intel_display_driver_register (Jouni) - mention xe in commit message v7: - update xe driver - reword commit message v6: - use 'i915' for i915 device (Jouni) - remove unnecessary code for non-atomic mode setting (Jouni, Ville) - fix function name in commit message (Jouni) v3: - as before, silently ignore devices without displays v2: - let drm_client_register() handle initial hotplug - fix driver name in error message (Jani) - fix non-fbdev build (kernel test robot) Signed-off-by:

Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Fox xe, remove xe_display_last_close(), which restored the fbdev display. As with i915, the DRM core's drm_lastclose() performs this operation automatically. v8: - mention xe in commit message v7: - update xe driver v6: - return errors from client callbacks (Jouni) Signed-off-by:

Unregister all in-kernel clients before unloading the i915 driver. For other drivers, drm_dev_unregister() does this automatically. As i915 and xe do not use this helper, they have to perform the call by themselves. Note that there are currently no in-kernel clients in i915 or xe. The patch prepares the drivers for a related update of their fbdev support. v8: - unregister clients in intel_display_driver_unregister() (Jani) - mention xe in commit message (Rodrigo, Jani) v7: - update xe driver Signed-off-by:

Initialize i915's fbdev client by giving an instance of struct drm_client_funcs to drm_client_init(). Also clean up with drm_client_release(). Doing this in i915 prevents fbdev helpers from initializing and releasing the client internally (see drm_fb_helper_init()). No functional change yet; the client callbacks will be filled later. v6: - rename client to "intel-fbdev" (Jouni) v2: - call drm_fb_helper_unprepare() in error handling (Jani) - fix typo in commit message (Sam) Signed-off-by:

Most users of _MMIO_PIPE3() and _MMIO_PORT3() need to add the MMIO base to the registers. Convert the macros to _MMIO_BASE_PIPE3() and _MMIO_BASE_PORT3() to move the base addition until after the register selection. If the register address depends on DISPLAY_MMIO_BASE(), this removes the need to figure the base out for each register, and it only needs to be added once. Reviewed-by:

Stop relying on the dev_priv local variable in the DSI register macros. Pass struct intel_display pointer to the macros. Move the MIPI DSI MMIO base selection to a different level, passing it to _MMIO_MIPI() and doing the addition there. Start using the local display variable for all intel_de_* usage, and opportunistically use it for other things than display registers as well. Reviewed-by:

The dmc_firmware_path parameter is clearly a display parameter. Move it there so it's available to both i915 and xe modules. This also cleans up the ugly member in struct xe_device. v2: - New try with the NULL/"" param value issue resolved Reviewed-by:

Jani Nikula authored
The distinction between the dmc_firmware_path module param being NULL and the empty string "" is problematic. It's not possible to set the parameter back to NULL via sysfs or debugfs. Remove the distinction, and consider NULL and the empty string to be the same thing, and use the platform default for them. This removes the possibility to disable DMC (and runtime PM) via i915.dmc_firmware_path="". Instead, use "/dev/null" as the magic firmware path to skip DMC firmware loading and disable runtime PM. v2: Add support for i915.dmc_firmware_path="/dev/null" (Gustavo) Cc: Gustavo Sousa <gustavo.sousa@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by:

Clarify request_firmware() error handling. Don't proceed to trying to parse non-existent firmware or check for payload when request_firmware() failed to begin with. There's no reason to release_firmware() either when request_firmware() failed. Also move the message about DMC firmware homepage here, as in other cases the user probably has some firmware, although its parsing fails for some reason. Reviewed-by:

Enabling the 5k@60Hz uncompressed mode on the MediaTek/Dell U3224KBA monitor results in a blank screen, at least on MTL platforms on UHBR link rates with some (<30) uncompressed bpp values. Enabling compression fixes the problem, so do that for now. Windows enables DSC always if the sink supports it and forcing it to enable the mode without compression leads to the same problem above (which suggests a panel issue with uncompressed mode). The same 5k mode on non-UHBR link rates is not affected and lower resolution modes are not affected either. The problem is similar to the one fixed by the HBLANK expansion quirk on Synaptics hubs, with the difference that the problematic mode has a longer HBLANK duration. Also the monitor doesn't report supporting HBLANK expansion; either its internal MST hub does the expansion internally - similarly to the Synaptics hub - or the issue has another root cause, but still related to the mode's short HBLANK duration. Enable the quirk for the monitor adjusting the detection for the above differences. v2: Rebase on drm_dp_128132b_supported() change. Cc: dri-devel@lists.freedesktop.org Reviewed-by:

The DPCD OUI of the logical port on a Dell UHBR monitor - on which the AUX device is used to enable DSC - is all 0. To detect if the HBLANK expansion quirk is required for this monitor use the OUI of the port's parent instead. Since in the above case the DPCD of both the logical port and the parent port reports being a sink device (vs. branch device) type, read the proper sink/branch OUI based on the DPCD device type. This is required by a follow-up patch enabling the quirk for the above Dell monitor. Reviewed-by:
