* fbdev: Add FOURCC-based format configuration APILaurent Pinchart2011-12-191-0/+306
| | | | | | | | | | | This API will be used to support YUV frame buffer formats in a standard way. Last but not least, create a much needed fbdev API documentation and document the format setting APIs.

* udlfb: Enable fb_defio by defaultBernie Thompson2011-08-241-8/+16
| | | | | | | | | | | | | | | | Enables page fault based detection of mmap writes to the framebuffer, which allows standard fbdev apps (like the generic fbdev xorg driver) to work on DisplayLink devices. Not all bugs are shaken out of the fb_defio path of udlfb, but it's tantalizingly close, so this seems a good time to enable by default. Alternatively, option can be disabled when running with an xorg driver that can more directly communicate damaged regions of the framebuffer via IOCTL. This is a simpler, higher perf option, when available. Signed-off-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
* udlfb: Add module option to do without shadow framebufferStuart Hopkins2011-08-241-0/+5
| | | | | | | | | | | | | | | By default, udlfb allocates a 2nd buffer to shadow what's across the bus on the USB device. It can operate without this shadow, but then it cannot tell which pixels have changed, and must send all. Saves host memory, but worsens the USB 2.0 bus bottleneck. This option allows users in very low memory situations (e.g. bifferboard) to optionally turn off this shadow framebuffer.

* DRM: clean up and document parsing of video= parameterRolf Eike Beer2011-07-251-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The video= parameter of the DRM drivers supports some additional flags that the normal fb drivers do not have. They also allow to limit these flags to specific outputs. Both things were previously undocumented. Also the parsing of the line had some oddities: -A lot of misplaced options were silently ignored or partly rejected instead of stopping the parsing immediately -The 'R' option is documented to follow the 'M' option if specified. It is not documented that 'M' is needed to specify 'R' (also this is the case for normal fb drivers). In fact the code is correct for normal fb drivers but wrong for DRM ones. The old code allowed 'R' only _before_ 'M' (since it parses backwards) and only if 'M' is given at all which is not needed for the DRM drivers. -the margins option ('m') was parsed but later ignored even if the later functions support it. -specifying multiple enable options at the same time did not lead to an error. -specifying something bogus for horizontal resolution (i.e. other things as digits) did not lead to an error but an invalid resolution was used. If any errors are encountered the position of the faulting string is now printed to the user and the complete mode is ignored. This gives much more consistent error behaviour. I also removed some useless assignments and changed the local flag variables to be bool. Signed-off-by: Rolf Eike Beer <eike-kernel@sf-tec.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | udlfb has undergone a fair bit of cleanup recently and is effectively at the point where it can be liberated from staging purgatory and promoted to a real driver.

* matroxfb: make CONFIG_FB_MATROX_MULTIHEAD=y mandatoryJean Delvare2009-09-231-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I would like to get rid of option CONFIG_FB_MATROX_MULTIHEAD and just always enable it. There are many reasons for doing this: * CONFIG_FB_MATROX_MULTIHEAD=y is what all x86 distributions do, so it definitely works or we would know by now. * Building the matroxfb driver with CONFIG_FB_MATROX_MULTIHEAD not set results in the following build warning: drivers/video/matrox/matroxfb_crtc2.c: In function 'matroxfb_dh_open': drivers/video/matrox/matroxfb_crtc2.c:265: warning: the address of 'matroxfb_global_mxinfo' will always evaluate as 'true' drivers/video/matrox/matroxfb_crtc2.c: In function 'matroxfb_dh_release': drivers/video/matrox/matroxfb_crtc2.c:285: warning: the address of 'matroxfb_global_mxinfo' will always evaluate as 'true' This is nothing to be worried about, the driver will work fine, but build warnings are still annoying. * The trick to get multihead support without CONFIG_FB_MATROX_MULTIHEAD, which is described in the config help text, no longer works: you can't load the same kernel module more than once. * I fail to see how CONFIG_FB_MATROX_MULTIHEAD=y would make the code significantly slower, contrary to what the help text says. A few extra parameters on the stack here and there can't really slow things down in comaprison to the rest of the code, and register access. * The driver built without CONFIG_FB_MATROX_MULTIHEAD is larger than the driver build with CONFIG_FB_MATROX_MULTIHEAD=y by 8%. * One less configuration option makes things simpler. We add options all the time, being able to remove one for once is nice. It improves testing coverage. And I don't think the Matrox adapters are still popular enough to warrant overdetailed configuration settings. * We should be able to unobfuscate the driver code quite a bit after this change (patches follow.)

* fbdev: remove cyblafb driverKrzysztof Helt2009-04-0110-634/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | A tridentfb driver has all the functionality of the cyblafb driver without the bugs of the latter. Changes to the tridentfb driver: - FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter for scrolling which is faster than color expansion on Cyberblade chipsets. The blitter is slower on a discrete Blade3D core. Use the blitter for scrolling in the tridentfb only for integrated Blade3D cores. Now, scrolling speed is about equal for the tridentfb and the cyblafb. - a copyright notice addition is done on request of Jani Monoses (the first author of the tridentfb).

* [ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devicesEric Miao2008-12-291-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PXA27x and later processors support overlay1 and overlay2 on-top of the base framebuffer (although under-neath the base is also possible). They support palette and no-palette RGB formats, as well as YUV formats (only available on overlay2). These overlays have dedicated DMA channels and behave in a similar way as a framebuffer. This heavily simplified and re-structured work is based on the original pxafb_overlay.c (which is pending for mainline merge for a long time). The major problems with this pxafb_overlay.c are (if you are interested in the history): 1. heavily redundant (the control logics for overlay1 and overlay2 are actually identical except for some small operations, which are now abstracted into a 'pxafb_layer_ops' structure) 2. a lot of useless and un-tested code (two workarounds which are now fixed on mature silicons) 3. cursorfb is actually useless, hardware cursor should not be used this way, and the code was actually un-tested for a long time. The code in this patch should be self-explanatory, I tried to add minimum comments. As said, this is basically simplified, there are several things still on the pending list: 1. palette mode is un-supported and un-tested (although re-using the palette code of the base framebuffer is actually very easy now with previous clean-up patches) 2. fb_pan_display for overlay(s) is un-supported 3. the base framebuffer can actually be abstracted by 'pxafb_layer' as well, which will help further re-use of the code and keep a better and consistent structure. (This is the reason I named it 'pxafb_layer' instead of 'pxafb_overlay' or something alike) See Documentation/fb/pxafb.txt for additional usage information.

* [ARM] pxafb: allow video memory size to be configurableEric Miao2008-12-291-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | The amount of video memory size is decided according to the following order: 1. <xres> x <yres> x <bits_per_pixel> by default, which is the backward compatible way 2. size specified in platform data 3. size specified in module parameter 'options' string or specified in kernel boot command line (see updated Documentation/fb/pxafb.txt) And now since the memory is allocated from system memory, the pxafb_mmap can be removed and the default fb_mmap() should be working all right. Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA descriptors and palettes, the allocation can be separated cleanly. NOTE: the LCD DMA actually supports chained transfer (i.e. page-based transfers), to simplify the logic and keep the performance (with less TLB misses when accessing from memory mapped user space), the memory is allocated by alloc_pages_*() to ensures it's physical contiguous.

| | | | | | | | | | | | | | | | | | Add support for Intel's 945GME graphics chip to the intelfb driver. I have assumed that the 945GME is identical to the already-supported 945GM apart from its PCI IDs; this is based on a quick look at the X driver for these chips which seems to treat them identically. The 945GME is used in the ASUS Eee 901, and I coded this in the hope that I'd be able to use it to get a console at the native 1024x600 resolution which is not known to the BIOS. I realised too late that the intelfb driver does not support mode changing on laptops, so it won't be any use for me.

* PM/gxfb: add hook to PM console layer that allows disabling of suspend VT switchAndres Salomon2008-04-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | Prior to suspend, we allocate and switch to a new VT; after suspend, we switch back to the original VT. This can be slow, and is completely unnecessary if the framebuffer we're using can restore video properly. This adds a hook that allows drivers to select whether or not to do this vt switch, and changes the gxfb driver to call this hook. It also adds a module param to gxfb to allow controlling of the vt switch (defaulting to no switch). (Note: I'm not convinced that console_sem is the best way to protect this, but we should probably have some form of locking..)

* fbdev: defio and MetronomefbJaya Kumar2008-03-192-0/+91
| | | | | | | | | | | | | | | | Implement support for the E-Ink Metronome controller. It provides an mmapable interface to the controller using defio support. It was tested with a gumstix pxa255 with Vizplex media using Xfbdev and various X clients such as xeyes, xpdf, xloadimage. This patch also fixes the following bug: Defio would cause a hang on write access to the framebuffer as the page fault would be called ad-infinitum. It fixes fb_defio by setting the mapping to be used by page_mkclean. Signed-off-by: Jaya Kumar <jayakumar.lkml@gmail.com> Cc: "Antonino A.

* fbdev: mm: Deferred IO supportJaya Kumar2007-05-081-0/+75
| | | | | | | | | | | | | | | | | This implements deferred IO support in fbdev. Deferred IO is a way to delay and repurpose IO. This implementation is done using mm's page_mkwrite and page_mkclean hooks in order to detect, delay and then rewrite IO. This functionality is used by hecubafb. [adaplas] This is useful for graphics hardware with no directly addressable/mappable framebuffer. Implementing this will allow the "framebuffer" to be accesible from user space via mmap().
