2008-10-16radeonfb: accelerate imageblit and other improvementsBenjamin Herrenschmidt
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.

2008-10-16radeonfb: misc cleanup of engine and dst cache handlingBenjamin Herrenschmidt
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: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: David S.

There is no such thing as a "device name size" in the driver core, so remove the define and fix up any users of this odd define in the rest of the kernel. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

RTRACE() does exactly the same thing as the standard pr_debug() call, so just use the latter.

2008-04-28radeonfb: fix debug optionJean Delvare
Fix CONFIG_FB_RADEON_DEBUG. DEBUG must be defined before including any kernel header, otherwise dev_dbg() resolves to a no-op. Also, when debugging is disabled, don't set DEBUG at all instead of setting it to 0, to comply with what the kernel headers expect.

2007-10-16Radeonfb Xpress 200M RC410 supportSellout Bessie
Make radeonfb work ith the 200m Xpress RC410. In my tests it was terribly unstable and would freeze until I set a refresh rate in the kernel argument to 75. e.g video=radeonfb:1280x800@75 Now it is rock solid.

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.

2006-06-25[PATCH] Rewritten backlight infrastructure for portable Apple computersMichael Hanselmann
This patch contains a total rewrite of the backlight infrastructure for portable Apple computers. Backward compatibility is retained. A sysfs interface allows userland to control the brightness with more steps than before. Userland is allowed to upload a brightness curve for different monitors, similar to Mac OS X.

2005-09-29[RADEON]: Fix unaligned I/O port access during probe.David S. Miller
The driver does a readl() on DEVICE_ID which is 2-byte aligned and 2-bytes in size. It's doing this read just to flush write buffers. Create IN16() and OUT16() macros, and use the former to do this I/O load. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
