For user-provided fonts, the framebuffer layer is using a magic
negative-indexing macro, FNTCHARCNT(), to keep track of their number of
characters:
#define FNTCHARCNT(fd) (((int *)(fd))[-3])
For built-in fonts, it is using hard-coded values (256). This results in
something like the following:
map.length = (ops->p->userfont) ?
FNTCHARCNT(ops->p->fontdata) : 256;
This is unsatisfactory. In fact, there is already a `charcount` field in
our virtual console descriptor (see `struct console_font` inside `struct
vc_data`), let us use it:
map.length = vc->vc_font.charcount;
Recently we added a `charcount` field to `struct font_desc`. Use it to set
`vc->vc_font.charcount` properly. The idea is:
- We only use FNTCHARCNT() on `vc->vc_font.data` and `p->fontdata`.
Assume FNTCHARCNT() is working as intended;
- Whenever `vc->vc_font.data` is set, also set `vc->vc_font.charcount`
properly;
- We can now replace `FNTCHARCNT(vc->vc_font.data)` with
`vc->vc_font.charcount`;
- Since `p->fontdata` always point to the same font data buffer with
`vc->vc_font.data`, we can also replace `FNTCHARCNT(p->fontdata)` with
`vc->vc_font.charcount`.
In conclusion, set `vc->vc_font.charcount` properly in fbcon_startup(),
fbcon_init(), fbcon_set_disp() and fbcon_do_set_font(), then replace
FNTCHARCNT() with `vc->vc_font.charcount`. No more if-else between
negative-indexing macros and hard-coded values.
Do not include <linux/font.h> in fbcon_rotate.c and tileblit.c, since they
no longer need it.
Depends on patch "Fonts: Add charcount field to font_desc".

sti_select_fbfont() and sti_cook_fonts() are hard-coding the number of
characters of our built-in fonts as 256. Recently, we included that
information in our kernel font descriptor `struct font_desc`, so use
`fbfont->charcount` instead of hard-coded values.

implementations
.con_font_set and .con_font_default callbacks should not pass `struct
console_font *` as a parameter, since `struct console_font` is a UAPI
structure.
We are trying to let them use our new kernel font descriptor, `struct
font_desc` instead. To make that work slightly easier, first delete all of
their no-op implementations used by dummy consoles.
This will make KD_FONT_OP_SET and KD_FONT_OP_SET_DEFAULT ioctl() requests
on dummy consoles start to fail and return `-ENOSYS`, which is intended,
since no user should ever expect such operations to succeed on dummy
consoles.

Recently in commit 3c4e0dff2095 ("vt: Disable KD_FONT_OP_COPY") we
disabled the KD_FONT_OP_COPY ioctl() option. Delete all the
con_font_copy() callbacks, since we no longer use them.
Mark KD_FONT_OP_COPY as "obsolete" in include/uapi/linux/kd.h, just like

We've fixed many races in panfrost_job_timedout() but some remain.
Instead of trying to fix it again, let's simplify the logic and move
the reset bits to a separate work scheduled when one of the queue
reports a timeout.
v5:
- Simplify panfrost_scheduler_stop() (Steven Price)
- Always restart the queue in panfrost_scheduler_start() even if
the status is corrupted (Steven Price)
v4:
- Rework the logic to prevent a race between drm_sched_start()
(reset work) and drm_sched_job_timedout() (timeout work)
- Drop Steven's R-b
- Add dma_fence annotation to the panfrost_reset() function (Daniel Vetter)
v3:
- Replace the atomic_cmpxchg() by an atomic_xchg() (Robin Murphy)
- Add Steven's R-b
v2:
- Use atomic_cmpxchg() to conditionally schedule the reset work
(Steven Price)

Copy over the width/height in millimeters to the
(somewhat redundant) display info, and set up the
bus format and bus flags for the display.
When used as DPI this display requires DE to be
active low and pixel data to be output on the
negative edge. It might be that it was previously
used with a display controller that either does
not support these settings or was hardcoded to use
these as default. This information comes from the
source code of the Samsung GT-I9070 mobile phone.

The comment about them (also removed) says:
/* fb_rsrc and aper_rsrc aren't really used currently, but still exist
* in case we decide we need information on the BAR for BSD in the
* future.
*/
Well that was written 12 years ago in 2008. We are now in the future
and they are still superfluous. We can always add them again at a
later date if they are ever required.

Some media power gates are disabled by default. commit 5d86923060fc
("drm/i915/tgl: Enable VD HCP/MFX sub-pipe power gating")
tried to enable it, but it duplicated an existent register.
So, the main PG setup sequences ended up overwriting it.
So, let's now merge this to the main PG setup sequence.
v2: (Chris): s/BIT/REG_BIT, remove useless comment,
remove useless =0, use the right gt,
remove rc6 sequence doubt from commit message.

Increase the scaled image's theorical width/height until we find a
configuration that has valid scaling coefficients, up to 102% of the
screen's resolution. This makes sure that we can scale from almost
every resolution possible at the cost of a very small distorsion.
The CRTC_W / CRTC_H are not modified.
This algorithm was already in place but would not try to go above the
screen's resolution, and as a result would only work if the CRTC_W /
CRTC_H were smaller than the screen resolution. It will now try until it
reaches 102% of the screen's resolution.
Note that this algorithm exists mostly as a band-aid for a missing
functionality: it is not possible for userspace to request the closest
mode that would encapsulate the provided one, because the GEM buffer is
created beforehand. If there was a way to let the kernel tweak the mode,
I could write a better algorithm that would result in a better looking
picture.

Currently drivers get called to move a buffer, but if they have to
move it temporarily through another space (SYSTEM->VRAM via TT)
then they can end up with a lot of ttm->driver->ttm call stacks,
if the temprorary space moves requires eviction.
Instead of letting the driver do all the placement/space for the
temporary, allow it to report back (-EMULTIHOP) and a placement (hop)
to the move code, which will then do the temporary move, and the
correct placement move afterwards.
This removes a lot of code from drivers, at the expense of
adding some midlayering. I've some further ideas on how to turn
it inside out, but I think this is a good solution to the call
stack problems.
v2: separate out the driver patches, add WARN for getting
MULTHOP in paths we shouldn't (Daniel)
v3: use memset (Christian)

e.g. the source device only support DP1.2 and the mst device support DP1.4.
