Remove the cursor timer (cursor flashing) on the following conditions: - if vc is in KD_GRAPHICS mode, ie, when X owns the console - if vc is blanked This misbehavior was exposed by Dave Jones. Signed-off-by:

Every time the console cursor blinks, we do a kmalloc/kfree pair. This patch turns that into a single allocation. This allocation was the most frequent kmalloc I saw on my test box. [adaplas] Per Alan's suggestion, move global variables to fbcon's private structure. This would also avoid resource leaks when fbcon is unloaded. Signed-off-by:

Adds functionality to read the EDID information over the DDC bus in a generic way. This code is based on the DDC implementation in the radeon driver. [adaplas] - separate from fbmon.c and place in new file fb_ddc.c - remove dependency to CONFIG_I2C and CONFIG_I2C_ALGOBIT, otherwise, feature will not compile if i2c support is compiled as a module - feature is selectable only by drivers needing it. It must have a 'select FB_DDC if xxx' in Kconfig - change printk's to dev_*, the i2c people prefers it Signed-off-by:

- add cursor enable/disable, very useful if you wish a full screen boot logo. Cursor can be disabled from kernel command line: video=au1100fb:nocursor,panel:Toppoly_TD035STED4 or from sysfs interface: echo 1 > /sys/module/au1100fb/parameters/nocursor - fix up some wrong indentation issues.

Michal Miroslaw reported a problem (bugzilla #7023) where a user initiated reset while the IDE layer was already resetting the channel caused a crash, and provided a rough fix. This is a slightly cleaner version of the fix which tracks the reset state and blocks further reset requests while a reset is in progress. Note this is not a security issue - random end users can't access the ioctl in question anyway. Signed-off-by:

Add a step to the IDE PM state machine that reprograms disk PIO timings as the first step on resume. This prevents ide deadlock on resume-from-ram on my nforce3-based laptop. An earlier implementation was written entirely within the amd74xx ide driver, but Alan helpfully pointed out that this is the correct thing to do globally. Still, I'm only calling hwif->tuneproc() for disks, based on two things: - The existing state machine is already passed over for non-disk drives - Previous testing on my laptop shows that the hangs are related only to the disk - suspend/resume from a livecd showed that there's no need for this on the cdrom.

There are three flags being set by default by the PIIX driver for speeds > PIO 1, and one not being cleared properly on fallback to PIO0. The most important one is the prefetch/post write control which only works for ATA and can do bad things with ATAPI. The patch does its best to set the flags correctly for drivers/ide. Its not 100% perfect but its closer than the original. 100% perfect requires proper IORDY handling but this isn't critical (and its not right in libata either .. yet) Sergei Shtylyov <sshtylyov@ru.mvista.com> said: > + { 0, 0 }, > + { 0, 0 }, > + { 1, 0 }, > + { 2, 1 }, > + { 2, 3 }, }; > > pio = ide_get_best_pio_mode(drive, pio, 5, NULL); BTW, there's quite obvious error here which leads to access outside of timings[] if somebody passes PIO mode 5 (or autotuning code finds out that drive supports PIO mode 5). Could have been fixed while at it...

This patch allows me to use dma with my cd/dvd attached to my on board pdc20265 ide controller Alan sayeth: Looks sane. Would be nice to know if there is any documentation supporting this hack being safe but the logic makes sense.

ide_dma_speed() fails to actually honor the IDE drivers' mode support masks) because of the bogus checks -- thus, selecting the DMA transfer mode that the driver explicitly refuses to support is possible. Additionally, there is no check for validity of the UltraDMA mode data in the drive ID, and the function is misdocumented. Signed-off-by:

In 2.6.15.1 I encountered some IDE crashes when unplugging IDE cables to emulate disk errors. Below is a patch against 2.6.16 which I think still applies. 1. The first BUG_ON could trigger when a PREFLUSH IO fails (it would fail the original barrier request which hasn't been marked REQ_STARTED yet). 2. the rq could have been dequeued already (same as 1). 3. HWGROUP(drive)->rq could be NULL because of the ide_error() several lines earlier. Signed-off-by:
