When allocating a frame buffer, the number of bits per pixel needed is

This patch adds the following new sysfs frequency attributes;
- punit_req_freq_mhz
- throttle_reason_status
- throttle_reason_pl1
- throttle_reason_pl2
- throttle_reason_pl4
- throttle_reason_thermal

Now tiles have their own sysfs interfaces under the gt/
directory. Because RPS is a property that can be configured on a
tile basis, then each tile should have its own interface
The new sysfs structure will have a similar layout for the 4 tile

On a multi-tile platform, each tile has its own registers + GGTT
space, and BAR 0 is extended to cover all of them.
Up to four GTs are supported in i915->gt[], with slot zero
shadowing the existing i915->gt0 to enable source compatibility
with legacy driver paths. A
Now that we have tiles we want each of them to have its own
interface. A directory "gt/" is created under "cardN/" that will
contain as many diroctories as the tiles.
In the coming patches tile related interfaces will be added. For
now the sysfs gt structure simply has an id interface related
to
The "gt_is_root(struct intel_gt *gt)" helper return true if the
gt is the root gt, which means that its id is 0. Return false
otherwise.

With the upcoming multitile support each tile will have its own
local memory. Mark the current LMEM with the suffix '0' to
emphasise that it belongs to the root tile.

Hi,
This is the second series that prepares i915 to host multitile
platforms. It introduces the for_each_gt() macro that loops over
the tiles to perform per gt actions.
This patch is a combination of two patches developed originally
by Abdiel, who introduced some refactoring during probe, and

Beside reusing existing code, the main advantage of ref_tracker is
tracking per instance of wakeref. It allows also to catch double
put.
On the other side we lose information about the first acquire and
the last release, but the advantages outweigh it.

Extract the callstack tracking of intel_runtime_pm.c into its own
utility so that that we can reuse it for other online debugging of
scoped wakerefs.

Track every intel_gt_pm_get() until its corresponding release in
intel_gt_pm_put() by returning a cookie to the caller for acquire that
must be passed by on rleased. When there is an imbalance, we can see who
either tried to free a stale wakeref, or who forgot to free theirs.
