2006-10-03[PATCH] fbcon: Remove cursor timer if unusedAntonino A. Daplas
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.

2006-10-03[PATCH] fbcon: Use persistent allocation for cursor blinkingDave Jones
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.

support Add the ability to have pxafb use only certain fixed video modes (selected on a per platform basis). This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel). This mirrors the setup already used by w100fb. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

I wish I was happier about this patch. It'll serve as a placeholder for the moment. I'm still trying to get a G550 working in order to even reproduce the problem this patch introduces. I find that the G450 has jitter even without this patch, so it won't show me what the patch changed. At this point, I'll continue trying to get the G550 to work, and in parallel work with the G450 to work out the kinks. The patch is below.

2006-07-31[PATCH] rivafb/nvidiafb: race between register_framebuffer and *_bl_initGuido Guenther
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. Cc: "Antonino A.

2006-07-31[PATCH] radeonfb sleep fixesVolker Braun
Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw too much power when suspended to RAM, reducing drastically the battery lifetime. The solution is to enable suspend-to-D2 on these machines. They are whitelisted through their subsystem vendor/device ID. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=3022 The patch introduces a framework to alter the pm_mode and reinit_func fields of the radeonfb_info structure based on a whitelist. This should facilitate future hardware-dependent workarounds. The workaround for the Samsung P35 that is already in the radeonfb code has been rewritten using this framework. The behavior can be overridden with module options: i) video=radeonfb:force_sleep=1 enable suspend-to-D2 also on non-whitelisted machines (useful for testing new notebook models), ii) video=radeonfb:ignore_devlist=1 Disable checking the whitelist and do not apply any workarounds.

2006-07-31[PATCH] fbdev: statically link the framebuffer notification functionsAntonino A. Daplas
The backlight and lcd subsystems can be notified by the framebuffer layer of blanking events. However, these subsystems, as a whole, can function independently from the framebuffer layer. But in order to enable to the lcd and backlight subsystems, the framebuffer has to be compiled also, effectively sucking in a huge amount of unneeded code. To prevent dependency problems, separate out the framebuffer notification mechanism from the framebuffer layer and permanently link it to the kernel.
