* Drivers: video: remove __dev* attributes.Greg Kroah-Hartman2013-01-041-2/+2
| | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn2011-01-261-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the introduction of the acquire_console_sem calls in 0333d83509c7d8496c8965b5ba9bc0c98e83c259, kexecing can cause the kernel to deadlock: ps3fb_shutdown() -> unregister_framebuffer() -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND) -> fbcon_fb_unbind() -> unbind_con_driver() -> bind_con_driver() [ acquires console_sem ] -> fbcon_deinit() -> fbops->fb_release(newinfo, 0) -> ps3fb_release() -> ps3fb_sync() [ acquires console_sem ] This change avoids the deadlock by moving the acquire_console_sem() out of ps3fb_sync(), and puts it into the two other callsites, leaving ps3fb_release() to call ps3fb_sync() without the console semaphore. [Geert] - Corrected call sequence above - ps3fb_release() may be called with and without console_sem held. This is an inconsistency that should be fixed at the fb level, but for now, try to acquire console_sem in ps3fb_release(). I think it's safer to let ps3fb_release() try to acquire console_sem and not refresh the screen if it fails, than to call ps3fb_sync() without holding console_sem, as ps3fb_par may be modified at the same time, causing crashes or lockups. Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen when display flipping is disabled, which is an uncommon case (except during shutdown/kexec).

* ps3fb: don't keep the borders for non-fullscreen modes in XDR memoryGeert Uytterhoeven2007-10-161-56/+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.

* ps3fb: fix possible overlap of GPU command buffer and frame bufferGeert Uytterhoeven2007-10-161-27/+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.

* ps3fb: Fix spurious mode change failuresGeert Uytterhoeven2007-10-161-7/+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.
