To mirror the CPU page table from GPU side, we register a mmu interval
notifier (in the coming patch of this series). Core mm call back to
GPU driver whenever there is a change to certain virtual address range,
i.e., range is released or unmapped by user etc.
This patch implemented the GPU driver

Under the picture of svm, CPU and GPU program share one same
virtual address space. The backing store of this virtual address
space can be either in system memory or device memory. Since GPU
device memory is remaped as DEVICE_PRIVATE, CPU can't access it.
Any CPU access to device memory causes a pa

Update fb_is_primary device() on parisc to detect the primary display
device from the Linux device instance. Aligns the code with the other
architectures. A later patch will remove the fbdev dependency from the
function's interface.

On parisc, change detection of the primary framebuffer to test for
the Linux device instead of fbdev's fb_info in fb_is_primary_device().
Makes the test independent from fbdev.
This patchset is part of a larger effort to clean up the low-level
display handling. There are various functions that att
Store the ROM's parent device in each STI struct, so we can associate
the STI framebuffer with a device.
The new field will eventually replace the fbdev subsystem's info field,
which the function fb_is_primary_device() currently requires to detect
the firmware's output. By using the device instead

Rename the names of xfail files for Mediatek (mt8173 and mt8183),
Rockchip (rk3288 and rk3399), and Meson (g12b) to include
information about the tested driver and whether it is related
to display or GPU testing.

Mediatek 8173 and 8183 SOCs have a separate display controller
and GPU, with different drivers for each. Add support in drm-ci

Powervr driver was merged in linux kernel, but there's no mediatek
support yet. So disable the mt8173-gpu job which uses powervr driver.

Enable CONFIG_DRM_ANALOGIX_ANX7625 in the arm64 defconfig to get
display driver probed on the mt8183-kukui-jacuzzi-juniper machine.
arch/arm64/configs/defconfig has CONFIG_DRM_ANALOGIX_ANX7625=m,
but drm-ci don't have initrd with modules, so add
CONFIG_DRM_ANALOGIX_ANX7625=y in CI arm64 config.

Some ARM SOCs have a separate display controller and GPU, each with
different drivers. For mediatek mt8173, the GPU driver is powervr,
and the display driver is mediatek. In the case of mediatek mt8183,
the GPU driver is panfrost, and the display driver is mediatek.
