drm/amdgpu: Add amdgpu_atpx_get_dhandle()

2018-07-11T14:31:28+00:00

commit 4aa5d5eb82bb237d0bb3a38b2a7555054d018081 upstream.

Since it seems that some vendors are storing the ATIF ACPI methods under
the same handle that ATPX lives under instead of the device's own
handle, we're going to need to be able to retrieve this handle later so
we can probe for ATIF there.

drm/amdgpu: Make struct amdgpu_atif private to amdgpu_acpi.c

2018-07-11T14:31:24+00:00

commit 2cd5fe22d9a45cdf11c62bbe8db3ce9101207510 upstream.

Currently, there is nothing in amdgpu that actually uses these structs
other than amdgpu_acpi.c. Additionally, since we're about to start
saving the correct ACPI handle to use for calling ATIF in this struct
this saves us from having to handle making sure that the acpi_handle
(and by proxy, the type definition for acpi_handle and all of the other
acpi headers) doesn't need to be included within the amdgpu_drv struct
itself. This follows the example set by amdgpu_atpx_handler.c.

Also remove code duplication in write and read regs functions.
This also fixes potential missing unlock in amdgpu_debugfs_regs_write
in case get_user would fail.

v2: Add SRBM mutex locking.
v3: Fix TO counter and fix comment location.

2018-03-14T20:08:24+00:00

Drop the "kernel" and sg parameter and give the BO type to create
explicit to amdgpu_bo_create instead of figuring it out from the
parameters.

drm/amdgpu: implement mmio byte access helper for MB

2018-03-14T19:38:26+00:00

mailbox registers can be accessed with a byte boundry according
to BIF team, so this patch prepares register byte access
and will be used by following patches.

Actually, for mailbox registers once the byte field is touched even not changed,
the mailbox behaves, so we need the byte width accessing to those sort of regs.

drm/amdgpu: cleanups for vram lost handling

2018-03-01T16:52:41+00:00

1)create a routine "handle_vram_lost" to do the vram
recovery, and put it into amdgpu_device_reset/reset_sriov,
this way no need of the extra paramter to hold the
VRAM LOST information and the related macros can be removed.

3)show vram_recover failure if time out, and set TMO equal to
lockup_timeout if vram_recover is under SRIOV runtime mode.

4)report error if any ip reset failed for SR-IOV
