[ Upstream commit 74fa02c4a5ea1ade5156a6ce494d3ea83881c2d8 ]

Cache the PCI state before bus master is disabled. The saved state is
later used for other cases like restoring config space after mode-2
reset.

commit 03c6284df179de3a4a6e0684764b1c71d2a405e2 upstream.

This patch causes the following iounmap erorr and calltrace
iounmap: bad address 00000000d0b3631f

The original patch was unjustified because amdgpu_device_fini_sw() will
always cleanup the rmmio mapping.

This reverts commit eb4f139888f636614dab3bcce97ff61cefc4b3a7.

This ensures that the memory mapped by ioremap for adev-&gt;rmmio, is
properly handled in amdgpu_device_init(). If the function exits early
due to an error, the memory is unmapped. If the function completes
successfully, the memory remains mapped.

[ Upstream commit cb11ca3233aa3303dc11dca25977d2e7f24be00f ]

If any IP blocks allocate memory during their hw_fini() sequence
this can cause the suspend to fail under memory pressure.  Introduce
a new phase that IP blocks can use to allocate memory before suspend
starts so that it can potentially be evicted into swap instead.

[ Upstream commit 5095d5418193eb2748c7d8553c7150b8f1c44696 ]

Linux PM core has a prepare() callback run before suspend.

If the system is under high memory pressure, the resources may need
to be evicted into swap instead.  If the storage backing for swap
is offlined during the suspend() step then such a call may fail.

So move this step into prepare() to move evict majority of
resources and update all non-pmops callers to call the same callback.

commit 916361685319098f696b798ef1560f69ed96e934 upstream.

commit ab4750332dbe ("drm/amdgpu/sdma5.2: add begin/end_use ring
callbacks") caused GFXOFF control to be used more heavily and the
codepath that was removed from commit 0dee72639533 ("drm/amd: flush any
delayed gfxoff on suspend entry") now can be exercised at suspend again.

Users report that by using GNOME to suspend the lockscreen trigger will
cause SDMA traffic and the system can deadlock.

This reverts commit 0dee726395333fea833eaaf838bc80962df886c8.
