igafb: use framebuffer_alloc() to allocate fb_info struct

2009-06-17T02:47:58+00:00

Use the framebuffer_alloc() function to allocate the fb_info
structure so the structure is correctly initialized after allocation.

drivers/video: add missing pci_dev_get

2008-02-06T18:41:16+00:00

pci_get_device does a pci_dev_get, so pci_dev_put needs to be called in an
error case

The problem was fixed using the following semantic patch.

[SPARC]: Fix serial console device detection.

2007-07-20T23:59:26+00:00

The current scheme works on static interpretation of text names, which
is wrong.

The output-device setting, for example, must be resolved via an alias
or similar to a full path name to the console device.

Paths also contain an optional set of 'options', which starts with a
colon at the end of the path.  The option area is used to specify
which of two serial ports ('a' or 'b') the path refers to when a
device node drives multiple ports.  'a' is assumed if the option
specification is missing.

This was caught by the UltraSPARC-T1 simulator.  The 'output-device'
property was set to 'ttya' and we didn't pick upon the fact that this
is an OBP alias set to '/virtual-devices/console'.  Instead we saw it
as the first serial console device, instead of the hypervisor console.

The infrastructure is now there to take advantage of this to resolve
the console correctly even in multi-head situations in fbcon too.

Thanks to Greg Onufer for the bug report.

[PATCH] remove bogus con_is_present() prototypes

2007-02-12T17:48:41+00:00

Although gcc seems to accept "extern" prototypes after it has seen the
"static inline" function, that's not really correct.

[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] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHM

2006-06-25T17:00:55+00:00

Remove VM_LOCKED before remap_pfn range from device drivers and get rid of
VM_SHM.

remap_pfn_range() already sets VM_IO.  There is no need to set VM_SHM since
it does nothing.  VM_LOCKED is of no use since the remap_pfn_range does not
place pages on the LRU.  The pages are therefore never subject to swap
anyways.  Remove all the vm_flags settings before calling remap_pfn_range.

After removing all the vm_flag settings no use of VM_SHM is left.  Drop it.
