2007-10-16ps3fb: enhance horizontal panning on firmware 1.90 and upGeert Uytterhoeven1-41/+60
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 Uytterhoeven1-25/+40
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.

2007-10-16ps3fb: don't keep the borders for non-fullscreen modes in XDR memoryGeert Uytterhoeven1-56/+75
Don't keep the borders for non-fullscreen modes in XDR memory: - Extract ps3fb_sync_image() - Work around the alignment restrictions of L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT by using an offset with L1GPU_CONTEXT_ATTRIBUTE_DISPLAY_FLIP - Only copy the visible part of the screen on every vblank - Always put the real frame buffer at the start of video memory - Clear fullscreen DDR memory on mode change Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: "Antonino A.

2007-10-16ps3fb: use fb_info.par properlyGeert Uytterhoeven1-35/+57
ps3fb: Use fb_info.par properly: o Move mode-specific fields into struct ps3fb_par o Allocate struct ps3fb_par using framebuffer_alloc() o Protect access to ps3fb_par in ps3fb_sync() using the console semaphore (this semaphore is already held when ps3fb_set_par() is called) o Avoid calling ps3av_set_video_mode() if the actual video mode hasn't changed Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: "Antonino A.

2007-10-16ps3fb: fix possible overlap of GPU command buffer and frame bufferGeert Uytterhoeven1-27/+39
ps3fb: In the case of non-fullscreen video modes, there was a partial overlap of the GPU command buffer and the frame buffer. Fix and cleanup various issues with overlap and alignment: - Move the GPU command buffer from the beginning to the end of video memory - Exclude the GPU command buffer from the actual frame buffer memory - Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64 KiB, and don't waste memory if it's already aligned (for fullscreen modes) - Take into account the alignment when checking memory requirements and maximum number of frames - Make sure fb_fix_screeninfo.smem_start always points to the virtual frame buffer start, so we don't have to compensate for that in ps3fb_mmap() Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Cc: "Antonino A.

2007-10-16ps3fb: Fix spurious mode change failuresGeert Uytterhoeven1-7/+8
ps3fb: Add a `mode' parameter to ps3fb_get_res_table(), as in some cases it should check the full-screen flag of the _new_ video mode instead of the current video mode. This bug caused spurious mode change failures when switching between fullscreen and non-fullscreen modes using fbset, while ps3-video-mode worked fine.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki1-0/+1
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-02-12[PATCH] ps3: Virtual Frame Buffer DriverGeert Uytterhoeven1-0/+1229
Add the PS3 Virtual Frame Buffer Driver. As the actual graphics hardware cannot be accessed directly by Linux, ps3fb uses a virtual frame buffer in main memory. The actual screen image is copied to graphics memory by the GPU on every vertical blank, by making a hypervisor call.
