Only resource mapping, interrupt handling and a simple ioctl handler is done by the kernel part, the rest of the logic is implemented in DirectFB userspace. Graphic applications greatly benefit for line drawing, blend, and rectangle and triangle filling operations. Benchmarks done on a PXA303 using the df_dok benchmarking tool follow, where the value in square brackets show the CPU usage during that test.

Largely this is never necessary in drivers because we have a copy of the entire PROM device tree in the kernel and a set of of_*() interfaces to access it. Unfortunately there were some lingering prom calls in the atyfb driver, in particular prom_finddevice() was being called with an on-stack address which could be anywhere. This code is actually probing for information we already have, the PROM choosen console output device is stored in of_console_device so all of this nasty code consolidates into a one-line comparison. Next we have some prom_getintdefault() calls which are trivially transformed into the equivalent of_getintprop_default(). Special thanks to Fabio, who figured out exactly where the bootup was hanging. That made this bug trivial to fix. Reported-by: Fabio M.

The handling of the i2c bus is wrong: A 1 bit should not written to the i2c, these will be done by switch the i2c to input. Driving an 1 bit active is against the i2c spec. An active driven of a 1 bit will result in very strange error, depending which side is the more powerful one. In my case it depends on the temperature of the Display-Controller-EEprom: With an cold eprom a got the correct EDID datas, with a warm one some of the 1 bits was 0 :-( The same bug is also in the intelfb driver in the file drivers/video/intelfb/intelfb_i2c.c. The functions intelfb_gpio_setscl() and intelfb_gpio_setsda() do drive the 1 bit active to the i2c bus. But since i have no card which is used by the intelfb driver i cannot fix it.

Only tested with fbcon, since most fbdev-based software appears to only support 12bpp and up. It does not appear that this driver has worked for at least the entire 2.6.x series, perhaps since 2002. Hercules graphics hardware uses packed pixels horizontally, but rows are not linear. In other words, the pixels are not packed vertically. This means that custom imageblit, fillrect and copyarea need to be written specific to the hardware. * Removed the experimental acceleration option, since it is required for the hardware to work. * Fixed imageblit to work with fb_image's wider than 8 pixels. * Updated configuration text (HGA hardware is from 1984) Signed-off-by: Brent Cook <busterb@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

These modes have been kept disabled earlier due to dependencies between the potential two LCDC channels that are exported as two separate framebuffer devices. The dependency boils down to a byte swap register that is shared between multiple channels. With this patch applied all single channel LCDC hardware can chose freely from 16, 24 and 32 bpp. Dual channel LCDC must stick to the same setup for both channels. Without this patch only 16 bpp is fully supported. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
