If we force a plane update to fix up our half populated plane state
we'll also force on the pipe gamma for the plane (since we always
enable pipe gamma currently). If the BIOS hasn't programmed a sensible
LUT into the hardware this will cause the image to become corrupted.
Typical symptoms are a purple/yellow/etc. flash when the driver loads.
To avoid this let's program something sensible into the LUT when
we do the plane update. In the future I plan to add proper plane
gamma enable readout so this is just a temporary measure.

Depending on the transcoder enum values to translate from transcoder to
the corresponding CHICKEN_TRANS register can easily break if we add a
new transcoder. Add an explicit mapping instead, by using helpers to
look up the register instance either by transcoder or port (since
unconveniently the registers have both port and transcoder specific
bits).
While at it also check for the correctness of GEN, port, transcoder. I
wasn't sure if psr2_enabled can only be set for GEN9+, but that seems to
be the case indeed (see setting of sink_psr2_support in
intel_psr_init_dpcd()).
v2 (Ville):
- Make gen9_chicken_trans_reg() internal to intel_psr.c.
- s/trans/cpu_transcoder/

Add a comment to the pipe and transcoder enum definitions about our
assumption in the code about enum values for pipes and transcoders
with a 1:1 transcoder -> pipe mapping.
v2:
- Clarify more what are the assumptions about the enum values. (Ville)
v3: (Lucas)
- s/->/ -> / so it looks less like pointer dereferencing.
- Use pipe enums as initializers in the transcoder enum definition.

Depending on the transcoder enum values to translate from transcoder

the dependency by using an explicit mapping.
While at it also add a WARN for unexpected trancoders.

- Simplify things by defining flag shift values instead of indices.

Writeback connectors do not produce any on-screen output and require
special care for use. Such connectors are hidden from enumeration in
DRM resources by default, but they are still picked-up by fbdev.
This makes rather little sense since fbdev is not really adapted for
dealing with writeback.
Moreover, this is also a source of issues when userspace disables the
CRTC (and associated plane) without detaching the CRTC from the
connector (which is hidden by default). In this case, the connector is
still using the CRTC, leading to am "enabled/connectors mismatch" and
eventually the failure of the associated atomic commit. This situation
happens with VC4 testing under IGT GPU Tools.
Filter out writeback connectors in the fbdev helper to solve this.

QEMU keeps a vram reference to the last QXLCursorCmd it received.
This QXLCursorCmd command points to a QXLCursor instance (stored in vram
too). However, while the QXLCursorCmd memory is pinned, the QXLCursor
memory is not.
When booting a recent Fedora to its login screen while monitoring the
QXLCursorCmd QEMU holds, it's possible to see the QXLCursor memory
becoming invalid shortly after boot. Pinning that memory ensures that
that QXLCursor memory is not going to be moved by the guest kernel.
Moving the pin/unpin to qxl_release_list_add()/qxl_release_free_list()
would be a more generic fix. However, doing this quickly exhausts QXL
video memory, so more fixing would be needed before this is workable.

Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

This adds an optional function table on GEM objects.
The main benefit is for drivers that support more than one type of
memory (shmem,vram,cma) for their buffers depending on the hardware it
runs on. With the callbacks attached to the GEM object itself, it is
easier to have core helpers for the the various buffer types. The driver
only has to make the decision about buffer type on GEM object creation
and all other callbacks can be handled by the chosen helper.
drm_driver->gem_prime_res_obj has not been added since there's a todo to
put a reservation_object into drm_gem_object.

There are uniform, non-uniform and flexible erase flash configurations.
The non-uniform erase types, are the erase types that can _not_ erase
the entire flash by their own.
As the code was, in case flashes had flexible erase capabilities
(support both uniform and non-uniform erase types in the same flash
configuration) and supported multiple uniform erase type sizes, the
code did not sort the uniform erase types, and could select a wrong
erase type size.
Sort the uniform erase mask in case of flexible erase flash
configurations, in order to select the best uniform erase type size.
Uniform, non-uniform, and flexible configurations with just a valid
uniform erase type, are not affected by this change.
Uniform erase tested on mx25l3273fm2i-08g and sst26vf064B-104i/sn.
Non uniform erase tested on sst26vf064B-104i/sn.

The PixArt OEM mice are known for disconnecting every minute in
runlevel 1 or 3 if they are not always polled. So add quirk
ALWAYS_POLL for two Primax mice as well.
0x4e22 is the Dell MS111-P and 0x4d0f is the unbranded HP Portia
mouse HP 697738-001. Both were built until approx. 2014.
Those were the standard mice from those vendors and are still
around - even as new old stock.

Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

Since capturing the error state requires fiddling around with the GGTT
to read arbitrary buffers and is itself run under stop_machine(), it
deadlocks the machine (effectively a hard hang) when run in conjunction
with Broxton's VTd workaround to serialize GGTT access.
v2: Store the ERR_PTR in first_error so that the error can be reported
to the user via sysfs.
v3: Mention the quirk in dmesg (using info as per usual)

This patch changes to use rtnl_lock only during a reset to avoid
deadlock that could occur when a thread operating close is holding
rtnl_lock and waiting for reset_lock acquired by another thread,
which is waiting for rtnl_lock in order to set the number of tx/rx
queues during a reset.
Also, we now setting the number of tx/rx queues during a soft reset
for failover or LPM events.

The getter callers doesn't know the valid Physical Queues (PQ) values.
This patch makes sure that a valid PQ will always be returned.
The patch consists of 3 fixes:
- When qed_init_qm_get_idx_from_flags() receives a disabled flag, it
returned PQ 0, which can potentially be another function's pq. Verify
that flag is enabled, otherwise return default start_pq.
- When qed_init_qm_get_idx_from_flags() receives an unknown flag, it
returned NULL and could lead to a segmentation fault. Return default
start_pq instead.
- A modulo operation was added to MCOS/VFS PQ getters to make sure the
PQ returned is in range of the required flag.

In ena_remove() we have the following stack call:
ena_remove()
unregister_netdev()
ena_destroy_device()
netif_carrier_off()
Calling netif_carrier_off() causes linkwatch to try to handle the
link change event on the already unregistered netdev, which leads
to a read from an unreadable memory address.
This patch switches the order of the two functions, so that
netif_carrier_off() is called on a regiestered netdev.
To accomplish this fix we also had to:
1. Remove the set bit ENA_FLAG_TRIGGER_RESET
2. Add a sanitiy check in ena_close()
both to prevent double device reset (when calling unregister_netdev()
ena_close is called, but the device was already deleted in
ena_destroy_device()).
3. Set the admin_queue running state to false to avoid using it after
device was reset (for example when calling ena_destroy_all_io_queues()
right after ena_com_dev_reset() in ena_down)
