* fbdev: add support for handoff from firmware to hw framebuffersDave Airlie2009-06-161-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | With KMS we have ran into an issue where we really want the KMS fb driver to be the one running the console, so panics etc can be shown by switching out of X etc. However with vesafb/efifb built-in, we end up with those on fb0 and the KMS fb driver on fb1, driving the same piece of hw, so this adds an fb info flag to denote a firmware fbdev, and adds a new aperture base/size range which can be compared when the hw drivers are installed to see if there is a conflict with a firmware driver, and if there is the firmware driver is unregistered and the hw driver takes over. It uses new aperture_base/size members instead of comparing on the fix smem_start/length, as smem_start/length might for example only cover the first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB into the aperture, thus they would never overlap.

| | | | | | | | | | | | | MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one.

* [PATCH] vesafb: Fix incorrect logo colors in x86_64Antonino A. Daplas2006-04-111-6/+21
| | | | | | | | | | | | | | | | | | | Bugzilla Bug 6299: A pixel size of 8 bits produces wrong logo colors in x86_64. The driver has 2 methods for setting the color map, using the protected mode interface provided by the video BIOS and directly writing to the VGA registers. The former is not supported in x86_64 and the latter is enabled only in i386. Fix by enabling the latter method in x86_64 only if supported by the BIOS. If both methods are unsupported, change the visual of vesafb to STATIC_PSEUDOCOLOR.

* [PATCH] vesafb: Drop blank hookAntonino A. Daplas2006-01-101-37/+0
| | | | | | | | | | | | | | | | | | | | | | From: Bugzilla Bug 5351 "After resuming from S3 (suspended while in X), the LCD panel stays black . However, the laptop is up again, and I can SSH into it from another machine. I can get the panel working again, when I first direct video output to the CRT output of the laptop, and then back to LCD (done by repeatedly hitting Fn+F5 buttons on the Toshiba, which directs output to either LCD, CRT or TV) None of this ever happened with older kernels." This bug is due to the recently added vesafb_blank() method in vesafb. It works with CRT displays, but has a high incidence of problems in laptop users. Since CRT users don't really get that much benefit from hardware blanking, drop support for this.

* [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas2005-11-071-1/+0
| | | | | | | | | | | | | | | | | | | | According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

* [PATCH] vesafb: Fix display corruption on display blankAntonino A. Daplas2005-10-181-3/+3
| | | | | | | | | | | | | | | | | | | | Reported by: Bob Tracy <rct@gherkin.frus.com> "...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which I'm using the Vesa FB driver. When the machine has been idle for some time and the driver attempts to powerdown the display, rather than the display going blank, it goes gray with several strange lines. When I hit the "shift" key or other-wise wake up the display, the old video state is not fully restored..." vesafb recently added a blank method which has only 2 states, powerup and powerdown. The powerdown state is used for all blanking levels, but in his case, powerdown does not work correctly for higher levels of display powersaving. Thus, for intermediate power levels, use software blanking, and use only hardware blanking for an explicit powerdown.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
