<title>drm/amdgpu: Add kernel parameter support for ignoring bad page threshold</title>

<id>68daadf3d673568bb7122b1683fd8b0e27c55d9b</id>
<content type='text'>
When a GPU hits the bad_page_threshold, it will not be initialized by
the amdgpu driver. This means that the table cannot be cleared, nor can
information gathering be performed (getting serial number, BDF, etc).

If the bad_page_threshold kernel parameter is set to -2,
continue to initialize the GPU, while printing a warning to dmesg that
this action has been done

v2: squash in Luben's fix to restore RAS info reporting

If you set amdgpu.discovery=2 you can force the the driver to
fetch the IP discovery table from a file rather than from the
table shipped on the device.  This is useful for debugging and
for device bring up and emulation when the tables may be in flux.

For now we explicitly return -ENODEV for generic bindings.
Remove this check once IP discovery based checking is in place.

Replace uses of mem_encrypt_active() with calls to cc_platform_has() with
the CC_ATTR_MEM_ENCRYPT attribute.

Remove the implementation of mem_encrypt_active() across all arches.

For s390, since the default implementation of the cc_platform_has()
matches the s390 implementation of mem_encrypt_active(), cc_platform_has()
does not need to be implemented in s390 (the config option
ARCH_HAS_CC_PLATFORM is not set).

Problem:
When device goes into suspend and unplugged during it
then all HW programming during resume fails leading
to a bad SW during pci remove handling which follows.
Because device is first resumed and only later removed
we cannot rely on drm_dev_enter/exit here.

Fix:
Use a flag we use for PCIe error recovery to avoid
accessing registres. This allows to successfully complete
pm resume sequence and finish pci remove.
