git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v5.15-rc1:
UAPI Changes:
- Remove sysfs stats for dma-buf attachments, as it causes a performance regression.
Previous merge is not in a rc kernel yet, so no userspace regression possible.
Cross-subsystem Changes:
- Sanitize user input in kyro's viewport ioctl.
- Use refcount_t in fb_info->count
- Assorted fixes to dma-buf.
- Extend x86 efifb handling to all archs.
- Fix neofb divide by 0.
- Document corpro,gm7123 bridge dt bindings.
Core Changes:
- Slightly rework drm master handling.
- Cleanup vgaarb handling.
- Assorted fixes.
Driver Changes:
- Add support for ws2401 panel.
- Assorted fixes to stm, ast, bochs.
- Demidlayer ingenic irq.

The VGA arbitration is entirely based on pci_dev structures, so just pass
that back to the set_vga_decode callback.

All callers pass NULL as the irq_set_state argument, so remove it and
the ->irq_set_state member in struct vga_device.

Add a trivial wrapper for the unregister case that sets all fields to
NULL.

Currently as the workaround is applied the screen flickers. As a result
we do not achieve seamless boot experience.
Avoiding the issue in the common use-case might be hard, although we can
resolve it for dual GPU setups - when the "other" GPU is primary and/or
outputs are connected to it.
With this I was able to get seamless experience on my Intel/Nvidia box,
running systemd-boot and sddm/Xorg. Note that the i915 driver is within
initrd while the Nvidia one is not.
Without this patch, the splash presented by systemd-boot (UEFI BGRT) is
torn down as the code-path kicks in, leaving the monitor blank until the
login manager starts.
Same issue were reported with plymouth/grub, although personally I
wasn't able to get them to behave on my setup.

Use Coccinelle to convert most of the usage of INTEL_GEN() and IS_GEN()
in the display code to use DISPLAY_VER() comparisons instead. The
following semantic patch was used:
@@ expression dev_priv, E; @@
- INTEL_GEN(dev_priv) == E
+ IS_DISPLAY_VER(dev_priv, E)
@@ expression dev_priv; @@
- INTEL_GEN(dev_priv)
+ DISPLAY_VER(dev_priv)
@@ expression dev_priv; expression E; @@
- IS_GEN(dev_priv, E)
+ IS_DISPLAY_VER(dev_priv, E)
@@
expression dev_priv;
expression from, until;
@@
- IS_GEN_RANGE(dev_priv, from, until)
+ IS_DISPLAY_RANGE(dev_priv, from, until)
There are still some display-related uses of INTEL_GEN() in intel_pm.c
(watermark code) and i915_irq.c. Those will be updated separately.
v2:
- Use new IS_DISPLAY_RANGE and IS_DISPLAY_VER helpers. (Jani)

Using struct drm_device.pdev is deprecated. Convert i915 to struct
drm_device.dev. No functional changes.
v6:
* also remove assignment in selftests/ in a later patch (Chris)
v5:
* remove assignment in later patch (Chris)
v3:
* rebased
v2:
* move gt/ and gvt/ changes into separate patches

The implicit "dev_priv" local variable use has been a long-standing pain
point in the register access macros I915_READ(), I915_WRITE(),
POSTING_READ(), I915_READ_FW(), and I915_WRITE_FW().
Replace them with the corresponding new display engine register
accessors intel_de_read(), intel_de_write(), intel_de_posting_read(),
intel_de_read_fw(), and intel_de_write_fw().
No functional changes.
