OMAPDSS: DISPC: skip scaling calculations when not scaling

Current code calculates scaling factors for video overlays even when the
overlays are not scaled. Change the code to skip calculations when not
scaling.

This optimizes the code a bit, but also fixes a problem when configuring
an overlay for a disabled display: if the display is disabled we don't
necessarily know the pixel clock used when the display is enabled, and
in some cases (like HDMI) the pixel clock is set to zero until a proper
video mode is set later. A wrong pixel clock will mess up the
scaling calculations, causing an error like:

omapdss DISPC error: failed to set up scaling, required fclk rate = 0
Hz, current fclk rate = 170666666 Hz

A proper fix would be to check later whether the clocks are enough for the
scaling, at the point when the overlay or display is actually enabled,
but this patch removes the problem for now.

virtio-pci: fix use after free

Commit 31a3ddda166cda86d2b5111e09ba4bda5239fae6 introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.

For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.

We allocate/free all resources together with the
pci device, so we can leave the release method empty.

ACPI / cpuidle: Remove acpi_idle_suspend (to fix suspend regression)

After commit e978aa7d7d57 ("cpuidle: Move dev->last_residency update to
driver enter routine; remove dev->last_state") setting acpi_idle_suspend
to 1 by acpi_processor_suspend() causes the ACPI cpuidle routines to
return error codes continuously, which in turn causes cpuidle to lock up
(hard).

However, acpi_idle_suspend doesn't appear to be useful for any
particular purpose (it's racy and doesn't really provide any real
protection), so it can be removed, which makes the problem go away.

       Given all this, it's not worth bothering to try to fix
       the locks at this time.

12 years agodrm: try to restore previous CRTC config if mode set fails

drm: try to restore previous CRTC config if mode set fails

We restore the CRTC, encoder, and connector configurations, but if the
mode set failed, the attached display may have been turned off, so we
need to try set_config again to restore things to the way they were.

drm: drop select of SLOW_WORK

slow-work got killed in commit 181a51f6e0. This means that since v2.6.36
there is no Kconfig symbol SLOW_WORK. Apparently selecting that symbol
is a nop. Drop that select.

12 years agodrm: serialize access to list of debugfs files

drm: serialize access to list of debugfs files

Nouveau, when configured with debugfs, creates debugfs files for every
channel, so structure holding list of files needs to be protected from
simultaneous changes by multiple threads.

Without this patch it's possible to hit kernel oops in
drm_debugfs_remove_files just by running a couple of xterms with
looped glxinfo.
