drm/amd/powerplay: refine vce dpm update code on Cz.

2017-07-05T12:40:25+00:00

[ Upstream commit ab8db87b8256e13a62f10af1d32f5fc233c398cc ]

Program HardMin based on the vce_arbiter.ecclk
if ecclk is 0, disable ECLK DPM 0. Otherwise VCE
could hang if switching SCLK from DPM 0 to 6/7

drm/amd/powerplay: fix vce cg logic error on CZ/St.

2017-07-05T12:40:25+00:00

[ Upstream commit 3731d12dce83d47b357753ffc450ce03f1b49688 ]

can fix Bug 191281: vce ib test failed.

when vce idle, set vce clock gate, so the clock
in vce domain will be disabled.
when need to encode, disable vce clock gate,
enable the clocks to vce engine.

drm/etnaviv: trick drm_mm into giving out a low IOVA

2017-07-05T12:40:24+00:00

[ Upstream commit 3546fb0cdac25a79c89d87020566fab52b92867d ]

After rollover of the IOVA space, we want to get a low IOVA address,
otherwise the the games we play by remembering the last IOVA are
pointless. When we search for a free hole with DRM_MM_SEARCH_DEFAULT,
drm_mm will pop the next entry from the free holes stack, which will
likely be a high IOVA. By using DRM_MM_SEARCH_BELOW we can trick
drm_mm into reversing the search and provide us with a low IOVA.

drm/amdgpu: check ring being ready before using

2017-07-05T12:40:23+00:00

[ Upstream commit c5f21c9f878b8dcd54d0b9739c025ca73cb4c091 ]

Return success when the ring is properly initialized, otherwise return
failure.

Tonga SRIOV VF doesn't have UVD and VCE engines, the initialization of
these IPs is bypassed. The system crashes if application submit IB to
their rings which are not ready to use. It could be a common issue if
IP having ring buffer is disabled for some reason on specific ASIC, so
it should check the ring being ready to use.

Bug: amdgpu_test crashes system on Tonga VF.

drm/vmwgfx: Free hash table allocated by cmdbuf managed res mgr

2017-07-05T12:40:18+00:00

commit 82fcee526ba8ca2c5d378bdf51b21b7eb058fe3a upstream.

The hash table created during vmw_cmdbuf_res_man_create was
never freed. This causes memory leak in context creation.
Added the corresponding drm_ht_remove in vmw_cmdbuf_res_man_destroy.

Tested for memory leak by running piglit overnight and kernel
memory is not inflated which earlier was.

drm/ast: Handle configuration without P2A bridge

2017-07-05T12:40:17+00:00

commit 71f677a91046599ece96ebab21df956ce909c456 upstream.

The ast driver configures a window to enable access into BMC
memory space in order to read some configuration registers.

If this window is disabled, which it can be from the BMC side,
the ast driver can't function.

Closing this window is a necessity for security if a machine's
host side and BMC side are controlled by different parties;
i.e. a cloud provider offering machines "bare metal".

A recent patch went in to try to check if that window is open
but it does so by trying to access the registers in question
and testing if the result is 0xffffffff.

This method will trigger a PCIe error when the window is closed
which on some systems will be fatal (it will trigger an EEH
for example on POWER which will take out the device).

This patch improves this in two ways:

 - First, if the firmware has put properties in the device-tree
containing the relevant configuration information, we use these.

 - Otherwise, a bit in one of the SCU scratch registers (which
are readable via the VGA register space and writeable by the BMC)
will indicate if the BMC has closed the window. This bit has been
defined by Y.C Chen from Aspeed.

If the window is closed and the configuration isn't available from
the device-tree, some sane defaults are used. Those defaults are
hopefully sufficient for standard video modes used on a server.
