9428088c90 drm/qxl: reapply cursor after resetting primary
QXL associates mouse state with its primary plane.

Destroying a primary plane and putting a new one in place has the side
effect of destroying the cursor as well.

This commit changes the driver to reapply the cursor any time a new
primary is created. It achieves this by keeping a reference to the
cursor bo on the qxl_crtc struct.

This fix is very similar to

commit 4532b241a4 ("drm/qxl: reapply cursor after SetCrtc calls")

which got implicitly reverted as part of implementing the atomic
modeset feature.

4013e44ffa drm: qxl: remove pr_info message, stops log spamming
Simply mmap'ing /dev/dri/card0 repeatedly will spam the kernel
log with qxl_mmap information messages. The following example code
illustrates this:

int main(void)
{
	int fd = open("/dev/dri/card0", O_RDONLY);
	if (fd == -1)
		err(1, "open failed");

	for (;;) {
		void *m = mmap(NULL, 4096, PROT_READ,
			MAP_SHARED, fd, 0);
		if (m != MAP_FAILED)
			munmap(m, 4096);
	}
}

Stop the spamming by removing the pr_info message. Since the mmap'ing
returns -EINVAL there is no need for the pr_info message.

62676d10b4 qxl: alloc & use shadow for dumb buffers
This patch changes the way the primary surface is used for dumb
framebuffers.  Instead of configuring the bo itself as primary surface
a shadow bo is created and used instead.  Framebuffers can share the
shadow bo in case they have the same format and resolution.

On atomic plane updates we don't have to update the primary surface in
case we pageflip from one framebuffer to another framebuffer which
shares the same shadow.  This in turn avoids the flicker caused by the
primary-destroy + primary-create cycle, which is very annonying when
running wayland on qxl.

The qxl driver never actually writes to the shadow bo.  It sends qxl
blit commands which update it though, and the spice server might
actually execute them (and thereby write to the shadow) in case the
local rendering is kicked for some reason.  This happens for example in
case qemu is asked to write out a dump of the guest display (screendump
monitor command).

b0e07da3f5 qxl: fix primary surface handling
The atomic conversion of the qxl driver didn't got the primary surface
handling completely right.  It works in the common simple cases, but
fails for example when changing the display resolution using xrandr or
in multihead setups.

The rules are simple:  There is one primary surface.  Before defining a
new one you have to destroy the old one.

This patch makes qxl_primary_atomic_update() destroy the primary surface
before defining a new one.  It fixes is_primary flag updates.  It adds
is_primary checks so we don't try to update the primary surface in case
it already has the state we want it being in.

e1923ab3d0 drm/<drivers>: Drop fbdev info flags
- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
  the entire panic handling code in our fbdev emulation. We might
  restore kms panic output, but not through the bazillion of legacy
  code layers called fbdev/fbcon, there's just no way to make that
  work safely.

- With the module check change FBINFO_DEFAULT is always 0, so can be
  removed too.

That removes another change to cargo-cult stuff in kms drivers, yay!

2d856f94e6 qxl: fix qxl_conn_get_modes
Call qxl_add_monitors_config_modes() unconditionally.  Do all sanity
checks in that function.

Fix sanity checks.  monitors_config is the current monitor
configuration, whereas client_monitors_config is the configuration
requested by the spice client.  So when filling the mode list, based on
the spice client request, we need to look at
client_monitors_config->count not monitors_config->count.

c50fad8f62 qxl: read monitors config at boot
Try to read the client monitors config at driver load time, even without
explicit notification.  So in case that info was filled before the driver
loaded and we've missed the notifications because of that the settings
will still be used.

With that place we now have to take care to properly handle a empty client
monitors config, so we don't trip over an uninitialized client monitors
config.

ecefd94e8b qxl: drop mode_info.modes & related code.
very old qxl hardware revisions (predating qxl ksm support by a few
years) supported a fixed list of video modes only.  The list is still
provided by the virtual hardware, for backward compatibility reasons.

The qxl kms driver never ever looks at it, except for dumping it to
the kernel log at load time in case debug logging is enabled.  Drop
that pointless code.

861078381b drm: qxl: Don't alloc fbdev if emulation is not supported
If fbdev emulation is disabled, the QXL shutdown path will try to clean
a framebuffer that wasn't initialized, hitting the Oops below.  The
problem is that even when FBDEV_EMULATION is disabled we allocate the
qfbdev strutucture, but we don't initialize it.  The fix is to stop
allocating the memory, since it won't be used.  This allows the existing
verification in the cleanup hook to do it's job preventing the oops.

Now that we don't allocate the unused fbdev structure, we need to be
careful when dereferencing it in the PM suspend hook.

instead it is only pinned/unpinned between prepare_fb and cleanup_fb.
So, we no longer need a final unpin of the primary framebuffer when
disabling the crtc.

715a11fabb drm: qxl: Consolidate bo reservation when pinning
Every attempt to pin/unpin objects in memory requires
qxl_bo_reserve/unreserve calls around the pinning operation to protect
the object from concurrent access, which causes that call sequence to be
reproduced every place where pinning is needed.  In some cases, that
sequence was not executed correctly, resulting in potential unprotected
pinning operations.

This commit encapsulates the reservation inside a new wrapper to make
sure it is always handled properly.  In cases where reservation must be
done beforehand, for some reason, one can use the unprotected version
__qxl_bo_pin/unpin.

e4563f6ba7 drm: Rely on mode_config data for fb_helper initialization
Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure.  I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates.  The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Registering the connector explicitly right after creation is not
necessary for modesetting drivers, because drm_dev_register already takes
care of this on the core side, by calling drm_modeset_register_all.

In addition, performing the initialization too early will get in the way
of the load() hook removal, because the connector interface cannot be
published prior to registering the minors.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has

As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.

<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

272725c7db drm: Nuke fb->bits_per_pixel
Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

5360943f05 drm/qxl: Call drm_helper_mode_fill_fb_struct() before drm_framebuffer_init()
We want framebuffers to be mostly useable already before
drm_framebuffer_init() is called, and so we will start demanding that
all the interesting format/size/etc. information be filled in before
drm_framebuffer_init(). drm_helper_mode_fill_fb_struct() will do that
for us, so let's make sure it gets called before drm_framebuffer_init().

16571a8a43 drm/qxl: fix use of uninitialized variable
In function qxl_release_alloc(), when kmalloc() returns a NULL pointer,
it returns value 0 and parameter *ret is uninitialized. 0 means no error
to the callers of qxl_release_alloc(). The callers keep going and will
try to reference the uninitialized variable. This patch fixes the bug,
returning "-ENOMEM" when kmalloc() fails.

ff996e72a0 qxl: Allow resolution which are not multiple of 8
The use of drm_cvt_mode() in qxl_add_monitors_config_modes() means that
the resolutions we are going to present to user-space are going to be
rounded down to a multiple of 8. In the QXL arbitrary resolution case,
this is not useful.
This commit forces the actual width/height that was requested by the
client in the drm_display_mode structure rather than keeping the
rounded version.

9e3b317839 qxl: Don't notify userspace when monitors config is unchanged
When the QXL driver receives a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG interrupt,
we currently always notify userspace that there was some hotplug event.

However, gnome-shell/mutter is reacting to this event by attempting a
resolution change, which it does by issueing drmModeRmFB, drmModeAddFB,
and then drmModeSetCrtc. This has the side-effect of causing
qxl_crtc_mode_set() to tell the QXL virtual hardware that a primary
surface was destroyed and created. After going through QEMU and then the
remote SPICE client, a new identical monitors config message will be
sent, resulting in a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG interrupt to
be emitted, and the same scenario occurring again.

As destroying/creating the primary surface causes a visible screen
flicker, this makes the guest hard to use (
https://bugzilla.redhat.com/show_bug.cgi?id=1266484 ).

This commit checks if the screen configuration we received is the same
one as the current one, and does not notify userspace about it if that's
the case.

f54d186700 dma-buf: Rename struct fence to dma_fence
I plan to usurp the short name of struct fence for a core kernel struct,
and so I need to rename the specialised fence/timeline for DMA
operations to make room.

A consensus was reached in
https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
that making clear this fence applies to DMA operations was a good thing.
Since then the patch has grown a bit as usage increases, so hopefully it
remains a good thing!

(v2...: rebase, rerun spatch)
v3: Compile on msm, spotted a manual fixup that I broke.
v4: Try again for msm, sorry Daniel

associated with the crtc is lost, which leads to
disappearing mouse cursors on wayland sessions.

This commit changes the driver to reapply the cursor
any time SetCrtc is called. It achieves this by keeping
a reference to the cursor bo on the qxl_crtc struct.

d9a1f0b4eb drm: use drm_file to tag vm-bos
Rather than using "struct file*", use "struct drm_file*" as tag VM tag for
BOs. This will pave the way for "struct drm_file*" without any "struct
file*" back-pointer.

2b721f2077 drm: Protect fb_defio in drivers with CONFIG_KMS_FBDEV_EMULATION
For reasons that entirely elude me fb.h exposes all the structures,
even when it is not enabled. Except for special stuff like fb_defio.

Which means all the drivers which haven't yet switched over to the
defio support in the helpers and still roll their own, will fail
to compile when fbdev emulation is disabled. Protect just those
bits, as a gnarly reminder that conversion to the core defio helpers
would be good.
