f89f8c6baf drm/amdgpu: Guard against write accesses after device removal
This should prevent writing to memory or IO ranges possibly
already allocated for other uses after our device is removed.

v5:
Protect more places wher memcopy_to/form_io takes place
Protect IB submissions

v6: Switch to !drm_dev_enter instead of scoping entire code
with brackets.

v7:
Drop guard of HW ring commands emission protection since they
are in GART and not in MMIO.

d10d0daa20 drm/amdgpu: Handle IOMMU enabled case.
Problem:
Handle all DMA IOMMU group related dependencies before the
group is removed. Those manifest themself in that when IOMMU
enabled DMA map/unmap is dependent on the presence of IOMMU
group the device belongs to but, this group is released once
the device is removed from PCI topology.

Fix:
Expedite all such unmap operations to pci remove driver callback.

v5: Drop IOMMU notifier and switch to lockless call to ttm_tt_unpopulate
v6: Drop the BO unamp list
v7:
Drop amdgpu_gart_fini
In amdgpu_ih_ring_fini do uncinditional  check (!ih->ring)
to avoid freeing uniniitalized rings.
Call amdgpu_ih_ring_fini unconditionally.
v8: Add deatiled explanation

e9669fb782 drm/amdgpu: Add early fini callback
Use it to call disply code dependent on device->drv_data
before it's set to NULL on device unplug

v5:
Move HW finilization into this callback to prevent MMIO accesses
post cpi remove.

v7:
Split kfd suspend from device exit to expdite HW related
stuff to amdgpu_pci_remove

v8:
Squash previous KFD commit into this commit to avoid compile break.

Some of the stuff in amdgpu_device_fini such as HW interrupts

pci_remove while most of the stuff which relates to finilizing and
releasing driver data structures can be kept until

Remove redundant ras->supported, as this value
is also stored in adev->ras_features.

Use adev->ras_features, as that supercedes "ras",
since the latter is its member.

The dependency goes like this:
ras <== adev->ras_features <== hw_supported,
and is read as "ras depends on ras_features, which
depends on hw_supported." The arrows show the flow
of information, i.e. the dependency update.

"hw_supported" should also live in "adev".

Commit 4192f7b576 ("drm/amdgpu: unmap register bar on device init
failure") makes amdgpu_driver_unload_kms() skips amdgpu_device_fini(),
so the VGA clients remain registered. So when
vga_arbiter_notify_clients() iterates over registered clients, it causes
NULL pointer dereference.

Since there's no reason to register VGA clients that early, so solve
the issue by putting them after all the goto cleanups.

v2:
 - Remove redundant vga_switcheroo cleanup in failed: label.

Commit 4192f7b576 ("drm/amdgpu: unmap register bar on device init
failure") makes amdgpu_driver_unload_kms() skips amdgpu_device_fini(),
so the VGA clients remain registered. So when
vga_arbiter_notify_clients() iterates over registered clients, it causes
NULL pointer dereference.

Since there's no reason to register VGA clients that early, so solve
the issue by putting them after all the goto cleanups.

v2:
 - Remove redundant vga_switcheroo cleanup in failed: label.

e6c6338f39 drm/amd/amdgpu implement tdr advanced mode
[Why]
Previous tdr design treats the first job in job_timeout as the bad job.
But sometimes a later bad compute job can block a good gfx job and
cause an unexpected gfx job timeout because gfx and compute ring share
internal GC HW mutually.

[How]
This patch implements an advanced tdr mode.It involves an additinal
synchronous pre-resubmit step(Step0 Resubmit) before normal resubmit
step in order to find the real bad job.

1. At Step0 Resubmit stage, it synchronously submits and pends for the
first job being signaled. If it gets timeout, we identify it as guilty
and do hw reset. After that, we would do the normal resubmit step to
resubmit left jobs.

2. For whole gpu reset(vram lost), do resubmit as the old way.

then fail the whole device reset.

e3c1b0712f drm/amdgpu: Reset the devices in the XGMI hive duirng probe
In passthrough configuration, hypervisior will trigger the SBR(Secondary bus reset) to the devices
without sync to each other. This could cause device hang since for XGMI configuration, all the devices
within the hive need to be reset at a limit time slot. This serial of patches try to solve this issue
by co-operate with new SMU which will only do minimum house keeping to response the SBR request but don't
do the real reset job and leave it to driver. Driver need to do the whole sw init and minimum HW init
to bring up the SMU and trigger the reset(possibly BACO) on all the ASICs at the same time

6efa4b465c gpu/drm: ring_mirror_list --> pending_list
Rename "ring_mirror_list" to "pending_list",
to describe what something is, not what it does,
how it's used, or how the hardware implements it.

This also abstracts the actual hardware
implementation, i.e. how the low-level driver
communicates with the device it drives, ring, CAM,
etc., shouldn't be exposed to DRM.

The pending_list keeps jobs submitted, which are
out of our control. Usually this means they are
pending execution status in hardware, but the
latter definition is a more general (inclusive)
definition.

1bba36834c drm/amdgpu: add helper function for indirect reg access (v3)
Add helper function in order to remove RREG32/WREG32
in current pcie_rreg/wreg function for soc15 and
onwards adapters.
PCIE_INDEX/DATA pairs are used to access regsiters
outside of mmio bar in the helper functions.
The new helper functions help remove the recursion
of amdgpu_mm_rreg/wreg from pcie_rreg/wreg and
provide the oppotunity to centralize direct and
indirect access in a single function.

v2: Fixed typo and refine the comments

v3: Remove unnecessary volatile local variable

519b8b76f0 drm/amdgpu: Implement new guest side VF2PF message transaction (v2)
- Refactor the driver code to use amdgpu_virt_read_pf2vf_data
  and amdgpu_virt_write_vf2pf_data instead of writing all code in
  one function (which is the old amdgpu_virt_init_data_exchange)

- Adding a new transaction method for VF2PF message between host
  and guest driver. Guest side will periodically update VF2PF
  message in the framebuffer.

  In the new header, we include guest ucode information, guest
  framebuffer usage, and engine usage

- Clean up the old macros since they will cause compile error if
  the new transaction method is used

and adev->in_gpu_reset, to avoid reentering GPU recovery.

v2:
drop "? true : false" in the definition of amdgpu_in_reset

f1403342eb drm/amdgpu: revert "fix system hang issue during GPU reset"
The whole approach wasn't thought through till the end.

We already had a reset lock like this in the past and it caused the same problems like this one.

Completely revert the patch for now and add individual trylock protection to the hardware access functions as necessary.

This reverts commit df9c8d1aa2.

df9c8d1aa2 drm/amdgpu: fix system hang issue during GPU reset
when GPU hang, driver has multi-paths to enter amdgpu_device_gpu_recover,
the atomic adev->in_gpu_reset and hive->in_reset are used to avoid
re-entering GPU recovery.

During GPU reset and resume, it is unsafe that other threads access GPU,
which maybe cause GPU reset failed. Therefore the new rw_semaphore
adev->reset_sem is introduced, which protect GPU from being accessed by
external threads during recovery.

v2:
1. add rwlock for some ioctls, debugfs and file-close function.
2. change to use dqm->is_resetting and dqm_lock for protection in kfd
driver.
3. remove try_lock and change adev->in_gpu_reset as atomic, to avoid
re-enter GPU recovery for the same GPU hang.

v3:
1. change back to use adev->reset_sem to protect kfd callback
functions, because dqm_lock couldn't protect all codes, for example:
free_mqd must be called outside of dqm_lock;

If we are in RAS triggered situation and
BACO isn't support, emergency restart is needed,
and this code is only needed for some specific
cases(vega20 with given smu fw version).

After we add smu mode1 reset for sienna cichlid, we
need to share AMD_RESET_METHOD_MODE1 with psp mode1 reset,
so in amdgpu_device_gpu_recover, we need differentiate
which mode1 reset we are using, then decide if it's
a full reset and then decide if emergency restart is needed,
the logic will become much more complex.

After discussion with Hawking, move emergency restart logic
to an independent function.

728e7e0cd6 drm/amdgpu: Add autodump debugfs node for gpu reset v8
When GPU got timeout, it would notify an interested part
of an opportunity to dump info before actual GPU reset.

A usermode app would open 'autodump' node under debugfs system
and poll() for readable/writable. When a GPU reset is due,
amdgpu would notify usermode app through wait_queue_head and give
it 10 minutes to dump info.

After usermode app has done its work, this 'autodump' node is closed.
On node closure, amdgpu gets to know the dump is done through
the completion that is triggered in release().

There is no write or read callback because necessary info can be
obtained through dmesg and umr. Messages back and forth between
usermode app and amdgpu are unnecessary.

v2: (1) changed 'registered' to 'app_listening'
    (2) add a mutex in open() to prevent race condition

v3 (chk): grab the reset lock to avoid race in autodump_open,
          rename debugfs file to amdgpu_autodump,
          provide autodump_read as well,
          style and code cleanups

v4: add 'bool app_listening' to differentiate situations, so that
    the node can be reopened; also, there is no need to wait for
    completion when no app is waiting for a dump.

v5: change 'bool app_listening' to 'enum amdgpu_autodump_state'
    add 'app_state_mutex' for race conditions:
	(1)Only 1 user can open this file node
	(2)wait_dump() can only take effect after poll() executed.
	(3)eliminated the race condition between release() and
	   wait_dump()

v6: removed 'enum amdgpu_autodump_state' and 'app_state_mutex'
    removed state checking in amdgpu_debugfs_wait_dump
    Improve on top of version 3 so that the node can be reopened.

v7: move reinit_completion into open() so that only one user
    can open it.

v8: remove complete_all() from amdgpu_debugfs_wait_dump().

1 warning generated.

Multiplication happens first due to order of operations and both
NSEC_PER_SEC and 4 are long literals so the expression overflows. To
avoid this, make 4 an unsigned long long literal, which matches the
type of expires (u64).

3f12acc8d6 drm/amdgpu: put the audio codec into suspend state before gpu reset V3
At default, the autosuspend delay of audio controller is 3S. If the
gpu reset is triggered within 3S(after audio controller idle),
the audio controller may be unable into suspended state. Then
the sudden gpu reset will cause some audio errors. The change
here is targeted to resolve this.

However if the audio controller is in use when the gpu reset
triggered, this change may be still not enough to put the
audio controller into suspend state. Under this case, the
gpu reset will still proceed but there will be a warning
message printed("failed to suspend display audio").

V2: limit this for BACO and mode1 reset only
V3: try 1st to use pm_runtime_autosuspend_expiration() to
    query how much time is left. Use default setting on
    failure

1c6d567bdf drm/amdgpu: rework sched_list generation
Generate HW IP's sched_list in amdgpu_ring_init() instead of
amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(),
ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary.
This patch also stores sched_list for all HW IPs in one big
array in struct amdgpu_device which makes amdgpu_ctx_init_entity()
much more leaner.

v2:
fix a coding style issue
do not use drm hw_ip const to populate amdgpu_ring_type enum

v3:
remove ctx reference and move sched array and num_sched to a struct
use num_scheds to detect uninitialized scheduler list

dffa11b4f7 drm/amdgpu: adjust sequence of ip_discovery init and timeout_setting
what:
1)move timtout setting before ip_early_init to reduce exclusive mode
cost for SRIOV

2)move ip_discovery_init() to inside of amdgpu_discovery_reg_base_init()
it is a prepare for the later upcoming patches.

why:
in later upcoming patches we would use a new mailbox event --
"req_gpu_init_data", which is a callback hooked in adev->virt.ops and
this callback send a new event "REQ_GPU_INIT_DAT" to host to notify
host to do some preparation like "IP discovery/vbios on the VF FB"
and this callback must be:

A) invoked after set_ip_block() because virt.ops is configured during
set_ip_block()

B) invoked before ip_discovery_init() becausen ip_discovery_init()
need host side prepares everything in VF FB first.

current place of ip_discovery_init() is before we can invoke callback
of adev->virt.ops, thus we must move ip_discovery_init() to a place
after the adev->virt.ops all settle done, and the perfect place is in
amdgpu_discovery_reg_base_init()

for VI SRIOV chip (tonga & fiji), the BIF_IOV_FUNC_IDENTIFIER is at

9593f4d6a6 drm/amdkfd: refactor runtime pm for baco
So far the kfd driver implemented same routines for runtime and system
wide suspend and resume (s2idle or mem). During system wide suspend the
kfd aquires an atomic lock that prevents any more user processes to
create queues and interact with kfd driver and amd gpu. This mechanism
created problem when amdgpu device is runtime suspended with BACO
enabled. Any application that relies on kfd driver fails to load because
the driver reports a locked kfd device since gpu is runtime suspended.

However, in an ideal case, when gpu is runtime  suspended the kfd driver
should be able to:

 - auto resume amdgpu driver whenever a client requests compute service
 - prevent runtime suspend for amdgpu  while kfd is in use

This change refactors the amdgpu and amdkfd drivers to support BACO and
runtime power management.

For sriov and pp_onevf_mode, do not send message to set smu
status, because smu doesn't support these messages under VF.

Besides, it should skip smu_suspend when pp_onevf_mode is disabled.

7e13ad8964 drm: Avoid drm_global_mutex for simple inc/dec of dev->open_count
Since drm_global_mutex is a true global mutex across devices, we don't
want to acquire it unless absolutely necessary. For maintaining the
device local open_count, we can use atomic operations on the counter
itself, except when making the transition to/from 0. Here, we tackle the
easy portion of delaying acquiring the drm_global_mutex for the final
release by using atomic_dec_and_mutex_lock(), leaving the global
serialisation across the device opens.
