* [PATCH] fbdev: tag by scantype in sysfsDaniel R Thompson2006-06-26
| | | | | | | | | | | | Modify the sysfs description of a video mode such that modes are tagged with their scan type, (p)rogessive, (i)nterlaced, (d)ouble scan. For example, U:1920x1080i-50. This is useful to disambiguate some of the 'consumer' video timings found in CEA-861 (especially those for EDTV).

| | | | | | | | | | | | | This patch adds a new framebuffer driver for the Intel Based macs. This framebuffer is needed when booting from EFI to get something out the box.

* [PATCH] fbdev: Fix logo rotation if width != heightAntonino A. Daplas2006-06-26
| | | | | | | | | | | Logo drawing crashes or produces a corrupt display if the logo width and height are not equal. The dimensions are transposed prior to the actual rotation and the width is used instead of the height in the actual rotation code. These produce a corrupt image.

* [PATCH] neofb: fix unblank logic interfering with lid toggled backlightChristian Trefzer2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | This is a fix for the most annoying problem that remained with neofb: After "setterm -powersave powerdown" the console blanker will disable the backlight after the given timeout expires. If this happens after the lid has been shut, we read "LCD off" from the register and store that in the driver. Once the lid is opened, the backlight turns on, but any key press that would awaken the blanked console will switch the backlight off again. The workaround so far was to use the "display config toggle" Fn key combo - once if no external display is attached, otherwise as often as required to restore the desired display setup. The following patch fixes the issue at least for the LCD-only case, with no external monitor attached. Other display setup permutations are pending further testing, but so far I can guarantee at least no negative change in behaviour, if any at all.

And even though the pci_device_id table now has numerous entries, it is still not guaranteed that all supported devices are included or will be included.

* [PATCH] fbdev: More accurate sync range extrapolationAntonino A. Daplas2006-06-26
| | | | | | | | | | | | | | | | | The EDID block should specify the display's operating limits (vertical and horizontal sync ranges, and maximum dot clock). If not given by the EDID block, the ranges are extrapolated from the modelist. However, the computation used is only a rough approximation, and the resulting values may not reflect the actual capability of the display. This problem is frequently encountered when the EDID block has a single entry, the single mode entry will fail validation. To prevent this, calculate the values based on the same method used in fb_validate_mode().

* [PATCH] savagefb: Add state save and_restore hooksAntonino A. Daplas2006-06-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reported by: Rich (Bugzilla Bug 6417) "if savage driver is used in x.org together with savagefb, it results in seriously garbled and distorted screen - coupled with severe slowdowns." This bug is the result of Xorg unable to handle savagefb altering the hardware which results in X failing to start properly and/or failed console switching. Add savagefb_state_save and savagefb_state_restore. These hooks will only save and restore the extended VGA registers. Standard VGA registers will be left alone. This is enough to make savagefb play nicely with the latest Xorg savage driver, and perhaps with savage DRI. (Transient screen artifacts may appear before X loads and during console switches). (Unfortunately, blanking the screen also leaves Xorg in a blanked state, so I have to unblank the screen before Xorg loads. So I doubt if the transient screen artifacts will be completely invisible but hopefully it will only be for a shorter duration (not much).)

I thought about some race condition, but as this is an UP system, it leads to questions on how it can happen. If we look at EFLAGS: 00010202, we see that interrupts are enabled at the time of the crash (eflags & 0x200). Finally, I don't understand all the capi code, but I think that handle_minor_send() is racing somehow against capi_recv_message(), which call both capiminor_del_ack(). So if an IRQ occurs in the middle of capiminor_del_ack() and another instance of it is invoked, it leads to linked list corruption. I came up with the following patch. With this, I could not reproduce the crash anymore. Clearly, this is not the correct fix for the issue. As this seems to be some locking issue, there might be more locking issues in that code. For example, doesn't the whole struct capiminor have to be locked somehow?
