[PATCH] fbcon: fix limited scroll in SCROLL_PAN_REDRAW mode

2006-06-08T22:12:21+00:00

From: Malcom Parsons 

When scrolling up in SCROLL_PAN_REDRAW mode with a large limited scroll
region, the bottom few lines have to be redrawn.  Without this patch, the
wrong text is drawn into these lines, corrupting the display.

Observed in 2.6.14 when running an IRC client in the Nintendo DS linux
port.

I haven't tested if scrolling down has the same problem.

[PATCH] fbcon: fix scrollback with logo issue immediately after boot

2006-05-31T23:27:10+00:00

From: David Hollister 

After the system boots with the logo, if the first action is a scrollback, the
screen may become garbled.  This patch ensures that the softback_curr value is
updated along with softback_in following the scrollback.

[PATCH] fbcon: Save current display during initialization

2006-03-31T20:19:00+00:00

The current display was not saved during initialization.  This leads to hard
to track console corruption, such as a misplaced cursor, which is correctible
by switching consoles.  Fix this minor bug.

[PATCH] Don't pass boot parameters to argv_init[]

2006-03-31T20:18:53+00:00

The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).

And __setup() is used in obsolete_checksetup().

	start_kernel()
		-> parse_args()
			-> unknown_bootoption()
				-> obsolete_checksetup()

If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.

If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func().  If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].

Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.

This patch fixes a wrong usage of it, however fixes obvious one only.

[PARISC] Fix stifb with IOREMAP and a 64-bit kernel

2006-03-30T17:48:47+00:00

Kill various warnings when built using ioremap.
Remove stifb_{read,write} functions, which are now obsolete (and stack abusers!)
Disable stifb mmap() functionality on a 64-bit kernel, it will crash the
machine.

[PATCH] drivers/video: Use ARRAY_SIZE macro

2006-03-27T16:44:58+00:00

Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove
duplicates of ARRAY_SIZE.  Some coding style and trailing whitespaces are
also fixed.

Compile-tested where possible (some are other arch or BROKEN)

[PATCH] sparse: Fix warnings in newport driver about non-static functions

2006-03-27T16:44:57+00:00

There are more sparse warnings but fixing those will require some more work
than I want to do without hardware for testing at hand.

[PATCH] vgacon: Add support for soft scrollback

2006-03-27T16:44:55+00:00

The scrollback buffer of the VGA console is located in VGA RAM.  This RAM
is fixed in size and is very small.  To make the scrollback buffer larger,
it must be placed instead in System RAM.

This patch adds this feature.  The feature and the size of the buffer are
made as a kernel config option.  Besides consuming kernel memory, this
feature will slow down the console by approximately 20%.

[PATCH] vgacon: fix EGA cursor resize function

2006-03-27T16:44:55+00:00

This corrects cursor resize on ega boards: registers are write-only, so we
shouldn't even try to read them.  And on ega, 31/30 produces a flat cursor.
Using 31/31 is better: except with 32 pixels high fonts, it shouldn't show
up.

[PATCH] vgacon: no vertical resizing on EGA

2006-02-24T22:31:37+00:00

EGA boards suck: they mostly have write-only registers.  This is
particularly problematic for the overflow register: for being able to write
to it, we would have to handle vertical sync & such too, which (I'd say)
would potentially break a lot of configurations.  Instead, just disabling
vertical resize for EGA boards is just nice enough (horizontal resize still
works).
