According to the new init phases scheme we should initialize "SW-only" state not requiring accessing the device as the very first step, so that the reasoning about dependencies of later steps becomes easier. So move these init steps into a separate function. This also has the benefit of making the error path cleaner both in the new function and int i915_driver_load()/unload(). No functional change.

The only steps requiring device access is the fence and swizzling initialization, so split these out keeping them in their current place and move the rest of init steps earlier. v2-v3: - unchanged v4: - move call to i915_gem_detect_bit_6_swizzle() to i915_gem_load_init_fences() and preserve the original order of the detection of HW fence capailities wrt. swizzling (Chris) CC: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

This init step accesses the device, but doesn't have any device specific side effect. It also sets up some platform specific attributes that may be required early, so move it earlier. Signed-off-by:

Split out the part initing the clock gating hooks and move it earlier. Add a new NOP hook for platforms without the need to apply clockgating or workaround settings, so that the hook can be called unconditionally. Also add a WARN for future platforms that forget to add a hook. The rest of the hooks in intel_init_pm() should be inited in the same way, but atm some of the hooks are set only conditionally, so before doing this we need to make the setup unconditional and use instead some flags. v2: - add a NOP hook and WARN if no hook is set for the platform (Chris) - use the term hook instead of callback for these functions (Jani) v3: - remove the GEN4() check it's already covered by earlier platform checks (Chris) CC: Jani Nikula <jani.nikula@intel.com> CC: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

These are all SW only init steps not accessing the device and they only need the platform identification macros to work, which are already available earlier, so move these init steps earlier. Signed-off-by:

In full gpu reset we prime all engines and reset domains corresponding to each engine. Per engine reset is just a special case of this process wherein only a single engine is reset. This change is aimed to modify relevant functions to achieve this. There are some other steps we carry out in case of engine reset which are addressed in later patches. Reset func now accepts a mask of all engines that need to be reset. Where per engine resets are supported, error handler populates the mask accordingly otherwise all engines are specified. v2: ALL_ENGINES mask fixup, better for_each_ring_masked (Chris) v3: Whitespace fixes (Chris) v4: Rebase due to s/ring/engine Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

After unplugging a DP MST display from the system, we have to go through and destroy all of the DRM connectors associated with it since none of them are valid anymore. Unfortunately, intel_dp_destroy_mst_connector() doesn't do a good enough job of ensuring that throughout the destruction process that no modesettings can be done with the connectors. As it is right now, intel_dp_destroy_mst_connector() works like this: * Take all modeset locks * Clear the configuration of the crtc on the connector, if there is one * Drop all modeset locks, this is required because of circular dependency issues that arise with trying to remove the connector from sysfs with modeset locks held * Unregister the connector * Take all modeset locks, again * Do the rest of the required cleaning for destroying the connector * Finally drop all modeset locks for good This only works sometimes. During the destruction process, it's very possible that a userspace application will attempt to do a modesetting using the connector. When we drop the modeset locks, an ioctl handler such as drm_mode_setcrtc has the oppurtunity to take all of the modeset locks from us. When this happens, one thing leads to another and eventually we end up committing a mode with the non-existent connector: [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* failed to enable link training [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f [drm:intel_dp_start_link_train [i915]] *ERROR* failed to start channel equalization [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f [drm:intel_mst_pre_enable_dp [i915]] *ERROR* failed to allocate vcpi And in some cases, such as with the T460s using an MST dock, this results in breaking modesetting and/or panicking the system. To work around this, we now unregister the connector at the very beginning of intel_dp_destroy_mst_connector(), grab all the modesetting locks, and then hold them until we finish the rest of the function.

A small step moving us closer to DRM MIPI DSI code. Use enum mipi_dsi_pixel_format instead of our own. The first benefit is being able to use common mipi_dsi_pixel_format_to_bpp(). There's a little back and forth conversion with the VBT -> enum -> register, since we have just shoved the VBT value into the register directly. Longer term, all the VBT parsing and deciphering should be done in intel_bios.c, and abstracted there. Reviewed-by:

The enum mipi_dsi_pixel_format defines MIPI_DSI_FMT_RGB666 for the "loose" 24 bpp format and MIPI_DSI_FMT_RGB666_PACKED for the 18 bpp format. We have this the other way round, defining a loose version for 24 bpp. Follow suit with what's in enum mipi_dsi_pixel_format to avoid future confusion. Rename VID_MODE_FORMAT_RGB666 -> VID_MODE_FORMAT_RGB666_PACKED VID_MODE_FORMAT_RGB666_LOOSE -> VID_MODE_FORMAT_RGB666 Reviewed-by:
