Thanks to the OpenBSD Foundation for sponsoring this work,
patrick@ for helping adapt rockchip drm, kettenis@ and mpi@
for uvm discussions and various testers.

Change the prefix of UVM object functions to match NetBSD's.

For example uvm_objinit() becomes uvm_obj_init(). Reduce differences
between the trees and help porting new functions needed for UVM object
locking.

No functionnal change.

Call ttm_tt_unpopulate() instead of directly calling ttm_tt_unpopulate
function pointer in ttm_tt_swapout(). Reduces the diff to linux.

ok kettenis@

correct ttm_tt error paths if bus_dmamap_create() fails

Avoids a double free of gtt in amdgpu_ttm_tt_create() if the
bus_dmamap_create() call in ttm_sg_tt_init() fails and ttm_tt_destroy()
calls amdgpu_ttm_backend_destroy().

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping, patrick@ for helping adapt rockchip drm and many developers for
testing.

Use km_alloc() instead of mallocarray() when allocating ttm dma segments
to avoid running out of kmem space. Suggested by and ok kettenis@

Let drm(4) allocate memory without constraints if the hardware supports
64-bit DMA. Should reduce the pressure on DMA-reachable memory, which is
important since there are still cases where the pagedaemon ends up being
triggered continuously if we run out of DMA-reachable memory but have
plenty of memory left.

ok jsg@

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.

update ttm and radeondrm(4) to Linux 4.4.129

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update

correct ttm_tt error paths if bus_dmamap_create() fails

Avoids a double free of gtt in amdgpu_ttm_tt_create() if the
bus_dmamap_create() call in ttm_sg_tt_init() fails and ttm_tt_destroy()
calls amdgpu_ttm_backend_destroy().

update drm to linux 5.7

adds kernel support for
amdgpu: vega20, raven2, renoir, navi10, navi14
inteldrm: icelake, tigerlake

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping, patrick@ for helping adapt rockchip drm and many developers for
testing.

Use km_alloc() instead of mallocarray() when allocating ttm dma segments
to avoid running out of kmem space. Suggested by and ok kettenis@

Let drm(4) allocate memory without constraints if the hardware supports
64-bit DMA. Should reduce the pressure on DMA-reachable memory, which is
important since there are still cases where the pagedaemon ends up being
triggered continuously if we run out of DMA-reachable memory but have
plenty of memory left.

ok jsg@

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.

update ttm and radeondrm(4) to Linux 4.4.129

Compared to the previous Linux 3.8 based port this adds support for
KAVERI/KABINI/MULLINS APUs and OLAND/BONAIRE/HAINAN/HAWAII GPUs.

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

Change the prefix of UVM object functions to match NetBSD's.

between the trees and help porting new functions needed for UVM object
locking.

No functionnal change.

Call ttm_tt_unpopulate() instead of directly calling ttm_tt_unpopulate

KAVERI/KABINI/MULLINS APUs and OLAND/BONAIRE/HAINAN/HAWAII GPUs.

drm/ttm: fix the tt_populated check in ttm_tt_destroy()

add static back to the ttm functions
ok kettenis@

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

Use km_alloc() instead of mallocarray() when allocating ttm dma segments
to avoid running out of kmem space. Suggested by and ok kettenis@

Let drm(4) allocate memory without constraints if the hardware supports
64-bit DMA. Should reduce the pressure on DMA-reachable memory, which is
important since there are still cases where the pagedaemon ends up being
triggered continuously if we run out of DMA-reachable memory but have
plenty of memory left.

ok jsg@

Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.
