[WHY]
 Function "amdgpu_irq_update()" called by "amdgpu_device_ip_late_init()" is an atomic context.
 We shouldn't access registers through KIQ since "msleep()" may be called in "amdgpu_kiq_rreg()".

[HOW]
 Move function "amdgpu_virt_release_full_gpu()" after function "amdgpu_device_ip_late_init()",
 to ensure that registers be accessed through RLCG instead of KIQ.

18 months agodrm/exynos: Implement fbdev emulation as in-kernel client
Thomas Zimmermann [Thu, 30 Mar 2023 07:36:35 +0000 (09:36 +0200)]
drm/exynos: Implement fbdev emulation as in-kernel client

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.

Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to exynos_fbdev_setup() after exynos has registered its
DRM device. As in most drivers, exynos' fbdev emulation now acts
like a regular DRM client.

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_dev_unregister() releases the client automatically.
No further action is required within exynos. 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.

drm/i915: disable sampler indirect state in bindless heap

By default the indirect state sampler data (border colors) are stored
in the same heap as the SAMPLER_STATE structure. For userspace drivers
that can be 2 different heaps (dynamic state heap & bindless sampler
state heap). This means that border colors have to copied in 2
different places so that the same SAMPLER_STATE structure find the
right data.

This change is forcing the indirect state sampler data to only be in
the dynamic state pool (more convenient for userspace drivers, they
only have to have one copy of the border colors). This is reproducing
