There's no point in checking diff == c->vc_rows, because it can be true only when count == 0, but we already checked that. Additionally move variables used only in one block to this block. Signed-off-by:

The current EDID parser in the linux kernel ignores interlace modes. The patch looks for the edid interlace flag and adjusts the vertical resolution if it is found. Signed-off-by:

Some BIOSes return error codes when queried for information about modes from their own modelist. uvesafb treats this as an error case and bails out. Change this behavior so that broken modes do not prevent the driver from working. Only the failure to retrieve information about any usable video mode is considered to be an error case.

Implement support for HW color expansion of 1bpp images, along with some improvements to the FIFO handling and other accel operations. The offset fixup code is now unnecessary as the fbcon core will call our set_par upon switch back from KD_GRAPHICS before anything else happens. I removed it as it would slow down accel operations. The fifo wait has been improved to avoid hitting the HW register as often, and the various accel ops are now performing better caching of register values. Overall, this improve accel performances. The imageblit acceleration does result in a small overall regression in performances on some machines (on the order of 5% on some x86), probably becaus the SW path provides a better bus utilisation, but I decided to ingnore that as the performances is still very good, and on the other hand, some machines such as some sparc64 get a 3 fold performance improvement.

Fix a couple of incomplete tests of the chip families in the engine init/reset code and proper initialization of the destination cache mode. The result should better match what the latest X radeon driver does. Signed-off-by:

Remove imacfb entirely, merging its DMI table into the (otherwise very similar) efifb driver. This also adds hardware support for many of the newer Intel Apple hardware. This has been fairly well tested; we've been shipping it in Fedora for some time. Signed-off-by:

A memory clock value (MCLK) is changed to a minimum required by a current mode bandwidth. This usually lowers the MCLK to its minimum (50 MHz) thus decreasing the card performance. Just leave the MCLK value set by card BIOS. The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a jitter on the screen. A countermeasure is to use the MCLK as pixclock source instead of a VCLK. The patch implements this as well. Signed-off-by:

The 16bpp mode did not work on the Cirrus cards as the visual type was set to DIRECTCOLOR instead of TRUECOLOR. The Alpine family used one incorrect register setting so this 16bpp modes generated wrong horizontal frequency. Signed-off-by:

Add support for Intel's 945GME graphics chip to the intelfb driver. I have assumed that the 945GME is identical to the already-supported 945GM apart from its PCI IDs; this is based on a quick look at the X driver for these chips which seems to treat them identically. The 945GME is used in the ASUS Eee 901, and I coded this in the hope that I'd be able to use it to get a console at the native 1024x600 resolution which is not known to the BIOS. I realised too late that the intelfb driver does not support mode changing on laptops, so it won't be any use for me. Signed-off-by:
