If the user supplies EDID through firmware or debugfs override, the
driver callbacks are bypassed and the connector ELD does not get
updated, and audio fails. Set ELD for firmware and debugfs EDIDs too.
There should be no harm in gratuitously doing this for non HDMI/DP
connectors, as it's still up to the driver to use the ELD, if any.

Some of the crtc_compute_clock() still depended on encoder->new_crtc
since they didn't use intel_pipe_will_have_type() and used an open
coded version of that function instead. This patch replaces those with
the appropriate code that checks the atomic state intead.

The function intel_dp_set_drrs_state() would decide which pipe to
downclock based on the staged config for the given connector. However,
the result of that function is immediate, and it uses input values from
crtc->config, so it should be looking at the current crtc instead.

Pass a crtc_state to it and find whether the pipe has an encoder of a
given type by looking at the drm_atomic_state the crtc_state points to.
Until recently i9xx_get_refclk() used to be called indirectly from
vlv_force_pll_on() with a dummy crtc_state. That dummy crtc state is not
converted to be part of a full drm atomic state, so add a WARN in case
someone decides to call that again with a such dummy state. This was
removed in

This patch continues on the idea from "Track GEN6 page table usage".
From here on, in the steady state, PDEs are all pointing to the scratch
page table (as recommended in the spec). When an object is allocated in
the VA range, the code will determine if we need to allocate a page for
the page table. Similarly when the object is destroyed, we will remove,
and free the page table pointing the PDE back to the scratch page.
Following patches will work to unify the code a bit as we bring in GEN8
support. GEN6 and GEN8 are different enough that I had a hard time to
get to this point with as much common code as I do.
The aliasing PPGTT must pre-allocate all of the page tables. There are a
few reasons for this. Two trivial ones: aliasing ppgtt goes through the
ggtt paths, so it's hard to maintain, we currently do not restore the
default context (assuming the previous force reload is indeed
necessary). Most importantly though, the only way (it seems from
empirical evidence) to invalidate the CS TLBs on non-render ring is to
either use ring sync (which requires actually stopping the rings in
order to synchronize when the sync completes vs. where you are in
execution), or to reload DCLV. Since without full PPGTT we do not ever
reload the DCLV register, there is no good way to achieve this. The
simplest solution is just to not support dynamic page table
creation/destruction in the aliasing PPGTT.
We could always reload DCLV, but this seems like quite a bit of excess
overhead only to save at most 2MB-4k of memory for the aliasing PPGTT
page tables.
v2: Make the page table bitmap declared inside the function (Chris)
Simplify the way scratching address space works.
Move the alloc/teardown tracepoints up a level in the call stack so that
both all implementations get the trace.
v3: Updated trace event to spit out a name
v4: Aliasing ppgtt is now initialized differently (in setup global gtt)
v5: Rebase to latest code. Also removed unnecessary aliasing ppgtt check
for trace, as it is no longer possible after the PPGTT cleanup patch series
of a couple of months ago (Daniel).
v6: Implement changes from code review (Daniel):
- allocate/teardown_va_range calls added.
- Add a scratch page allocation helper (only need the address).
- Move trace events to a new patch.
- Use updated mark_tlbs_dirty.
- Moved pt preallocation for aliasing ppgtt into gen6_ppgtt_init.
v7: teardown_va_range removed (Daniel).
In init, gen6_ppgtt_clear_range call is only needed for aliasing ppgtt.
v8: Rebase after s/page_tables/page_table/.
v9: Remove unnecessary scratch flag in page_table struct, future patches
can just compare against ppgtt->scratch_pt, and alloc_pt_scratch becomes
redundant. Initialize scratch_pt and pt. (Mika)
v10: Clean up aliasing ppgtt init error path and prevent leaking the
ppgtt obj when init fails. (Mika)
Updated commit author. (Daniel)

If we retire requests last, we may use a later seqno and so clear
the requests lists without clearing the active list, leading to
confusion. Hence we should retire requests first for consistency with
the early return. The order used to be important as the lifecycle for
the object on the active list was determined by request->seqno. However,
the requests themselves are now reference counted removing the
constraint from the order of retirement.

The current code can only support one kgd instance. We have to
support multiple kgd instances in one system. i.e two amdgpu or two
radeon or one amdgpu + one radeon or more than two kgd instances.

Convert the timestamping in the amdkfd driver to use a timespec64 and 64bit
time accessors.
Although the existing code is completely safe beyond y2038 because it deals
with monotonic time, this patch is still needed in order to kill off all uses
of struct timespec.

fence_wait_timeout() is an exported kernel symbol, so we should rename our
local function to something different.

Pull of-graph helpers from Philipp Zabel:
of: Add of-graph helpers to loop over endpoints and find ports by id
This series converts of_graph_get_next_endpoint to decrement the refcount of
the passed prev parameter. This allows to add a for_each_endpoint_of_node
helper macro to loop over all endpoints in a device tree node.
The of_graph_get_port_by_id function is added to retrieve a port by its known
port id (contained in the reg property) from the device tree.

drm/i915: Ensure plane->state->fb stays in sync with plane->fb
v2: Don't move update_state_fb(). It was moved around because I
originally put update_state_fb() in intel_alloc_plane_obj() before
finding a better place. (Matt)

Setting a dev_pm_ops resume callback but not a set of hibernation
handler means that pm function will not be called upon hibernation.
Fix this by using SIMPLE_DEV_PM_OPS, which appropriately assigns the
suspend and hibernation handlers and move omap_dmm_resume under
CONFIG_PM_SLEEP to avoid build warnings.

We store the fb being page-flipped to 'old_fb' field, but we don't
increase the ref count of the fb when doing that. While I am not
sure if it can cause problem in practice, it's still safer to keep a ref
when storing a pointer to a fb.

The omapdrm DMM code sometimes crashes with:
WARNING: CPU: 0 PID: 1235 at lib/list_debug.c:36 __list_add+0x8c/0xbc()
list_add double add: new=e9265368, prev=e90139c4, next=e9265368.
This is caused by the code calling release_engine() twice for the same
engine.
dmm_txn_commit(wait=true) call is supposed to wait until the DMM
transaction has been finished. And it does that, but it does not wait
for the irq handler to finish.
What happens is that the irq handler is triggered, and it either wakes
up the thread that called dmm_txn_commit(), or that thread never even
slept because the transaction was finished in the HW very quickly. That
thread then continues executing, even if the irq handler is not yet
finished, and a new transaction may be initiated. If that transaction is
async (i.e. wait=false), a 'async' flag is set to true. The original irq
handler, which has yet not finished, then sees the transaction as
'async', even if it was supposed to be 'sync'.
When that happens, the irq handler does an extra release_engine() call
because it thinks it need to release the engine, leading to the crash.
This patch fixes the issue by using completion to ensure that the irq
handler has finished before a dmm_txn_commit(wait=true) may continue.
