[PATCH] backlight last round of fixes

2006-09-01T18:39:10+00:00

Fix some more problems (inverted use of semaphores in some places).  He
also moved my checks into within the protected section which is better.

[PATCH] fbdev: Fix crashes in various fbdev's blank routines

2006-08-31T04:21:55+00:00

The backlight changes that went in had a bug where they could cause the
kernel to access an unitialized pointer when blanking if there is no
backlight control on a machine.

The bug affects atyfb, aty128fb, nvidiafb and rivafb.  radeonfb seems to
be ok.  This fixes it.

[PATCH] rivafb/nvidiafb: race between register_framebuffer and *_bl_init

2006-07-31T20:28:45+00:00

Since we now use the generic backlight infrastructure, I think we need to
call rivafb_bl_init before calling register_framebuffer since otherwise
rivafb_bl_init might race with the framebuffer layer already opening the
device and setting up the video mode.  In this case we might end up with a
not yet fully intialized backlight (info->bl_dev still NULL) when calling
riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
dies without any further notice during boot.

This fixes booting current git on a PB 6,1.  In this case radeonfb/atyfb
would be affected too - I can fix that too but don't have any hardware to
test this on.

[PATCH] nvidiafb: remove redundant CONFIG_PCI check

2006-07-31T20:28:45+00:00

CONFIG_FB_NVIDIA already depends on CONFIG_PCI in drivers/video/Kconfig.
Driver does an extra ``sanity check'' which is then redundant.

[PATCH] powermac: Combined fixes for backlight code

2006-07-10T20:24:20+00:00

This patch fixes several problems:
- pmac_backlight_key() is called under interrupt context, and therefore
  can't use mutexes or semaphores, so defer the backlight level for
  later, as it's not critical (original code by Aristeu S. Rozanski F.
  ).
- Add exports for functions that might be called from modules
- Fix Kconfig depdencies on PMAC_BACKLIGHT.
- Fix locking issues on calls from inside the driver (reported by
  Aristeu S. Rozanski F., too)
- Fix wrong calculation of backlight values in some of the drivers
- Replace pmac_backlight_key_up/down by inline functions

[PATCH] vt: Remove VT-specific declarations and definitions from tty.h

2006-07-10T20:24:16+00:00

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one.  Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

[PATCH] Detaching fbcon: remove calls to pci_disable_device()

2006-06-26T16:58:32+00:00

Detaching fbcon allows individual drivers to be unloaded.  However several
drivers call pci_disable_device() upon exit.  This function will disable the
BAR's which will kill VGA text mode and/or affect X/DRM.

To prevent this, remove calls to pci_disable_device() from several drivers.

[PATCH] nvidiafb: Revise pci_device_id table

2006-06-26T16:58:29+00:00

nVidia is churning out chipsets like there's no tomorrow.  And even though the
pci_device_id table now has numerous entries, it is still not guaranteed that
all supported devices are included or will be included.

Fortunately, nvidiafb has chipset detection logic built in.  So, change the
contents of the pci_device_id table so it will capture all nVidia devices of
the display class.  Unsupported chipsets will then be filtered out by
nvidiafb's detection logic.
