2011-03-22fbcon: fix situation where fbcon gets deinitialised and can't reinit.Dave Airlie1-2/+2
Situation as follow: 2 GPUs + vesafb + kms. GPU 1 is primary, vesafb binds to it as fb0 radeon loads GPU 0 loads as fb1 GPU 1 loads, vesafb gets kicked off which causes fb0 to unbind console, which causes the dummy console to rebind. this means fbcon_deinit gets called, which calls fbcon_exit since the console isn't bound anymore and we set fbcon_has_exited. GPU 1 creates a new fb0 which is primary and we want to be console. fbcon_fb_registered gets called sets the primary up and calls set_con2fb_map, however as fbcon_has_exited is set nothing further ever happens. This patch bypasses the fbcon_has_exited and checks if the console is unbound, if its unbound it calls the fbcon_takeover which calls the vt layer to call the fbcon_startup method and everthing works.

2011-03-22video: Fix EDID macros H_SYNC_WIDTH and H_SYNC_OFFSETMartin Decky1-2/+2
The macros for getting the values for horizontal sync width and offset do not respect the EDID specification. Both these values are 10 bit values according to [1], not 6 bit values. The lower 8 bits are stored in byte 8 and byte 9 of the DTD respectively, while two additional bits for each value are stored in byte 11. The original macros just slammed the bits together. Although the original macros usually worked fine because the higher two bits are rarely used, it can cause severe problems on plasma panels running at 1920x1080 @ 50 Hz with drivers that rely on the correct parsing of the EDID data by fbmon.c (e.g. udlfb). The patch should apply cleanly to both the fbdev-2.6.git branch and linux-next.git branch.

2011-03-22fbcon: Bugfix soft cursor detection in Tile BlittingHenry Nestler1-1/+1
Use mask 0x10 for "soft cursor" detection on in function tile_cursor. (Tile Blitting Operation in framebuffer console). The old mask 0x01 for vc_cursor_type detects CUR_NONE, CUR_LOWER_THIRD and every second mode value as "software cursor". This hides the cursor for these modes (cursor.mode = 0). But, only CUR_NONE or "software cursor" should hide the cursor. See also 0x10 in functions add_softcursor, bit_cursor and cw_cursor.

2011-03-22uvesafb,vesafb: create WC or WB PAT-entriesThomas Schlichter2-29/+64
with an PAT-enabled kernel, when using uvesafb or vesafb, these drivers will create uncached-minus PAT entries for the framebuffer memory because they use ioremap() (not the *_cache or *_wc variants). When the framebuffer memory intersects with the video RAM used by Xorg, the complete video RAM will be mapped uncached-minus what results in a serve performance penalty. Here are the correct MTRR entries created by uvesafb: schlicht@netbook:~$ cat /proc/mtrr reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back reg01: base=0x06ff00000 ( 1791MB), size= 1MB, count=1: uncachable reg02: base=0x070000000 ( 1792MB), size= 256MB, count=1: uncachable reg03: base=0x0d0000000 ( 3328MB), size= 16MB, count=1: write-combining And here are the problematic PAT entries: schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list PAT memtype list: write-back @ 0x0-0x1000 uncached-minus @ 0x6fedd000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee3000-0x6fee4000 uncached-minus @ 0x6fee3000-0x6fee4000 uncached-minus @ 0x6fee3000-0x6fee4000 uncached-minus @ 0xd0000000-0xe0000000 <-- created by xserver-xorg uncached-minus @ 0xd0000000-0xd1194000 <-- created by uvesafb uncached-minus @ 0xf4000000-0xf4009000 uncached-minus @ 0xf4200000-0xf4400000 uncached-minus @ 0xf5000000-0xf5010000 uncached-minus @ 0xf5100000-0xf5104000 uncached-minus @ 0xf5400000-0xf5404000 uncached-minus @ 0xf5404000-0xf5405000 uncached-minus @ 0xf5404000-0xf5405000 uncached-minus @ 0xfed00000-0xfed01000 Therefore I created the attached patch for uvesafb which uses ioremap_wc() to create the correct PAT entries, as shown below: schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list PAT memtype list: write-back @ 0x0-0x1000 uncached-minus @ 0x6fedd000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee2000-0x6fee3000 uncached-minus @ 0x6fee3000-0x6fee4000 uncached-minus @ 0x6fee3000-0x6fee4000 uncached-minus @ 0x6fee3000-0x6fee4000 write-combining @ 0xd0000000-0xe0000000 write-combining @ 0xd0000000-0xd1194000 uncached-minus @ 0xf4000000-0xf4009000 uncached-minus @ 0xf4200000-0xf4400000 uncached-minus @ 0xf5000000-0xf5010000 uncached-minus @ 0xf5100000-0xf5104000 uncached-minus @ 0xf5400000-0xf5404000 uncached-minus @ 0xf5404000-0xf5405000 uncached-minus @ 0xf5404000-0xf5405000 uncached-minus @ 0xfed00000-0xfed01000 This results in a performance gain, objectively measurable with e.g. x11perf -comppixwin10 -comppixwin100 -comppixwin500: 1: x11perf_xaa.log 2: x11perf_xaa_patched.log 1 2 Operation -------- ---------------- ----------------- 124000.0 202000.0 ( 1.63) Composite 10x10 from pixmap to window 3340.0 24400.0 ( 7.31) Composite 100x100 from pixmap to window 131.0 1150.0 ( 8.78) Composite 500x500 from pixmap to window You can see the serve performance gain when composing larger pixmaps to window. The patches replace the ioremap() function with the variant matching the mtrr- parameter. To create "write-back" PAT entries, the ioremap_cache() function must be called after creating the MTRR entries, and the ioremap_cache() region must completely fit into the MTRR region, this is why the MTRR region size is now rounded up to the next power-of-two.

2011-03-22radeonfb: Let hwmon driver probe the "monid" I2C busJean Delvare1-0/+3
Some Radeon cards have an I2C-based thermal sensor chip connected to the "monid" I2C bus. Set the I2C probing class of this bus properly so that hwmon drivers can detect devices on it and bind to them. This closes kernel.org bug #26172. We exclude PPC for the time being, as Benjamin doesn't want us to mess up with them without explicit testing, and there is no evidence that this change is needed for them either.
