2007-11-29x86_64 EFI boot support: EFI frame buffer driverHuang, Ying
This patch adds Graphics Output Protocol support to the kernel. UEFI2.0 spec deprecates Universal Graphics Adapter (UGA) protocol and only Graphics Output Protocol (GOP) is produced. Therefore, the boot loader needs to query the UEFI firmware with appropriate Output Protocol and pass the video information to the kernel. As a result of GOP protocol, an EFI framebuffer driver is needed for displaying console messages. The patch adds a EFI framebuffer driver. The EFI frame buffer driver in this patch is based on the Intel Mac framebuffer driver. The ELILO bootloader takes care of passing the video information as appropriate for EFI firmware. The framebuffer driver has been tested in i386 kernel and x86_64 kernel on EFI platform.

2007-11-29atmel_lcdfb: LCDC startup fixAnti Sullin
This patch adds an additional loop, that delays turning off the DMA until the LCDC core has been turned off. This prevents the picture to be shifted some random length when the kernel re-initializes the LCDC. Without this patch, the LCDC keeps running for some small time after the PWRCON:LCD_PWR has been cleared ; the FIFO suffers an underrun and on re-starting the LCDC the FIFO data stays shifted. This behavior has been seen and fixed on AT91SAM9261-EK and two custom AT91SAM9261 boards, all of them having different LCD panels. Thanks a lot to Anti Sullin for submitting this patch (long time ago).

2007-11-29fb_ddc: fix DDC lines quirkJean Delvare
The code in fb_ddc_read() is said to be based on the implementation of the radeon driver: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc5891c8a3ba284f13994d7bc1f1bfa8283982de However, comparing the old radeon driver code with the new fb_ddc code reveals some differences. Most notably, the I2C bus lines are held at the end of the function, while the original code was releasing them (as the comment above correctly says.) There are a few other differences, which appear to be responsible for read failures on my system. While tracing low-level I2C code in i2c-algo-bit, I noticed that the initial attempt to read the EDID always failed. It takes one retry for the read to succeed. As we are about to remove this automatic retry property from i2c-algo-bit, reading the EDID would really fail. As a summary, the I2C lines quirk which is supposedly needed to read EDID on some older monitors is currently breaking the (first) read on all other monitors (and might not even work with older ones - did anyone try since October 2006?) After applying the patch below, which makes the code in fb_ddc_read() really similar to what the radeon driver used to have, the first EDID read succeeds again. On top of that, as it appears that this code has been broken for one year now and nobody seems to have complained, I'm curious if it makes sense to keep this quirk in place. It makes the code more complex and slower just for the sake of monitors which I guess nobody uses anymore. Can't we just get rid of it?

2007-10-19x86: convert cpuinfo_x86 array to a per_cpu arrayMike Travis
cpu_data is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpus. When NR_CPU count is raised to 4096 the size of cpu_data becomes 3,145,728 bytes. These changes were adopted from the sparc64 (and ia64) code. An additional field was added to cpuinfo_x86 to be a non-ambiguous cpu index. This corresponds to the index into a cpumask_t as well as the per_cpu index. It's used in various places like show_cpuinfo(). cpu_data is defined to be the boot_cpu_data structure for the NON-SMP case.

2007-10-16tgafb: remove a redundant non-mono test in mono imageblitMaciej W. Rozycki
There is a test in tgafb_mono_imageblit() for a colour image with a fall-back to cfb_imageblit(). The test is not necessary as the only caller, which is tgafb_imageblit(), checks it too and only invokes this function for monochrome images. It looks like a left-over from before some changes to tgafb_imageblit(). Signed-off-by: Maciej W.

2007-10-16tgafb: fix an out-of-range shift in mono imageblitMaciej W. Rozycki
The pixel mask calculation in tgafb_mono_imageblit() uses a variable left-shift on a 32-bit data type by up to 32. Shifting by the width of a data type or more produces an unpredictable result according to the C standard. Rather than widening the data type this fix makes sure the count is between 0 and 31. The reason is not to penalise 32-bit platforms with operation on a "long long" type for a marginal case that is meant not to happen (blitting an image of a zero width). The reason it has escaped for so long is the Alpha, being purely 64-bit, :-) does not mask the shift out to 32 bits. This is a valid implementation -- producing the correct result certainly falls within "unpredictable behaviour". It does trigger on MIPS though and it is the recent merge of the TC support which only enabled the driver for use on anything other than the Alpha. For MIPS when the width is 32 the mask ends up being 0 rather than 0xffffffff as it should be and the frame buffer is not updated. Signed-off-by: Maciej W.

2007-10-16fbcon: delay the start of the cursor timer until a con_switch()Antonino Daplas
As reported in Bugzilla Bug 9093, upon switching to X, a small rectangular cursor can still be seen blinking in the upper left part of the screen. It is fbcon's text cursor. This is caused by a strange ioctl(..., KDSETMODE, KD_TEXT) call done by something in userspace, perhaps by X itself, while the tty is still in graphics mode. And when the tty is in KD_TEXT mode, the cursor timer is restarted. Although this is a userspace problem, we can work around it by delaying the restart of the cursor timer until an fbcon_switch() is called. In other words, the cursor timer will not be restarted even if a KD_TEXT mode switch is requested.

2007-10-16fbdev: copyarea function taught to fully support swapped pixel order in bytePavel Pisa
This correct case, when source and destination X coordinates difference is n multiple of pixels in byte. This is probably rare case, but this case should supported for completeness. Reorganization of FB_READL and FB_WRITEL calls results in code size decrease for normal build without swapping support and size with support enabled is reasonable too.

2007-10-16s3fb: do not allow incorrect pixclock settingsKrzysztof Helt
This patch adds check if selected pixclock is valid (is in the PLL range). Previously, if the pixclock could not be set, the new mode resolution was set but pixclock was not set which led to incorrect timings sent to monitor. [adaplas] Fixed a few misplaced curly braces.

2007-10-16ps3fb: enhance horizontal panning on firmware 1.90 and upGeert Uytterhoeven
ps3fb: Enhance horizontal panning on firmware 1.90 and up: - On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying rectangles from XDR to DDR memory with different source and destination line lengths. Hence larger horizontal virtual resolutions can be supported (up to 16368 pixels). - As the actual frame buffer memory layout no longer matches the entries in ps3fb_res[], create fake struct ps3fb_ioctl_res data for the PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it keep on working.

2007-10-16ps3fb: add virtual screen and panning supportGeert Uytterhoeven
ps3fb: Add virtual screen and panning support: - The vertical virtual screen size is limited by the amount of memory reserved for ps3fb, - The horizontal virtual screen size is limited to the fullscreen width, - Advertise that we support panning, so fbcon will use it if the virtual screen is enabled. Enabling a virtual screen (using `fbset -vyres nnn') can speed up text console scrolling by a factor of 10-15, depending on the video mode.
