2024-04-25drm/{i915, xe}: Implement fbdev emulation as in-kernel clientThomas Zimmermann5-140/+80
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: Thomas Zimmermann <[email protected]> Reviewed-by: Jouni Högander <[email protected]> Acked-by: Lucas De Marchi <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Jani Nikula <[email protected]>
2024-04-25drm/{i915,xe}: Implement fbdev client callbacksThomas Zimmermann5-49/+25
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: Thomas Zimmermann <[email protected]> Reviewed-by: Jouni Högander <[email protected]> Acked-by: Lucas De Marchi <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Jani Nikula <[email protected]>
2024-04-25drm/{i915,xe}: Unregister in-kernel clientsThomas Zimmermann2-0/+4
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.

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.

2024-04-25gpu: drm: exynos: hdmi: eliminate uses of of_node_put()Shivani Gupta1-10/+5
Utilize the __free() cleanup handler within the hdmi_get_phy_io function to automatically release the device node when it is out of scope. This eliminates the manual invocation of of_node_put(), reducing the potential for memory leaks. The modification requires initializing the device node at the beginning of the function, ensuring that the automatic cleanup is safely executed. Consequently, this removes the need for error cleanup paths that utilize goto statements and the jump to out is no longer necessary.

2024-04-24drm/i915: Fix gt reset with GuC submission is disabledNirmoy Das1-2/+14
Currently intel_gt_reset() kills the GuC and then resets requested engines. This is problematic because there is a dedicated CSB FIFO which only GuC can access and if that FIFO fills up, the hardware will block on the next context switch until there is space that means the system is effectively hung. If an engine is reset whilst actively executing a context, a CSB entry will be sent to say that the context has gone idle. Thus if reset happens on a very busy system then killing GuC before killing the engines will lead to deadlock because of filled up CSB FIFO. To address this issue, the GuC should be killed only after resetting the requested engines and before calling intel_gt_init_hw(). v2: Improve commit message(John) Cc: John Harrison <[email protected]> Signed-off-by: Nirmoy Das <[email protected]> Reviewed-by: John Harrison <[email protected]> Reviewed-by: Andi Shyti <[email protected]> Signed-off-by: Andi Shyti <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2024-04-23drm/amdgpu: Update BO eviction prioritiesFelix Kuehling1-0/+2
