2014-11-22vivante: fix missing composite offsets for CopyWindow()HEADmasterRussell King
Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-11-22build: ensure m4 sub-directory is createdRussell King
Ensure autogen.sh creates the m4 sub-directory before running autoreconf, otherwise autotools fails. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-27packaging: add README and INSTALL filesRussell King
Add some of the usual documentation files to describe the package and the standard installation instructions. Signed-off-by: Russell King <rmk@arm.linux.org.uk>

2014-09-13src: fix failure to enter VTRussell King
If EnterVT fails, we end up segfaulting the server, because we have marked the vtSema true when this isn't the case - we try to LeaveVT twice, once for the fatal error (which causes a segfault) and once more as a result of the segfault. Ensure that we reset this flag when EnterVT fails to avoid this error. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-13vivante: validate source/destination formatsRussell King
Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-13vivante: split out the non-alpha workaroundRussell King
Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: add updated gal extensionRussell King
Work on etnaviv has standardised this extension. Use the new version instead, obsoleting the old version. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fix composite using non-alpha picturesRussell King
The Vivante GPU hardware appears to be buggy with some formats and mask combinations, and is particularly noticable with BGRA/RGBA swizzles with non-alpha formats. Fix this by switching to alpha formats, and subsituting a maximal global alpha value instead. This allows rendercheck to pass for all formats with PE20 hardware. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: better solid mask handlingRussell King
Improve the solid mask handling: we can do these checks earlier, and by doing so, allow more mask formats through to be rendered by hardware. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: remove unused BoxCopy()Russell King
BoxCopy() is not used, and is #if 0'd out. Remove it. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fix PutImage() positioning bugRussell King
xts finds that PutImage() fails. This is because PutImage() on a window drawable must include the drawables position on the pixmap, and this was not being taken into account. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fix FillSpans() X coordinateRussell King
FillSpans() x2 coordinate was undefined as it should be adding the width to the x1 coordinate. Fix this. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fix PolyFillRectSolid()Russell King
PolyFillRectSolid() must fill the rectangles in the order provided, and must not optimise overlaps (due to XOR and similar GC operations.) Re-architect the solid fill function to fill each rectangle in the provided order for each clip box. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fetch solid colour and convert to ARGB8888Russell King
When fetching the solid colour to fill the temporary composite pixmap, always ensure that it is formatted for ARGB8888 to match the destination format. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2014-09-12vivante: fix temporary composite pixmap to be 32-bit ARGB8888Russell King
The temporary composite pixmap was being created with a variable depth, but we were trying to place ARGB8888 formatted pixels into it. Fix by ensuring that this is always created with a depth of 32, and move the format initialisation to one place. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: move extraction of foreground colour to separate functionRussell King
Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fix PolyPoint() CoordModePreviousRussell King
The PolyPoint() CoordModePrevious implementation was incorrect - it only accounted for the previous point's relative position, not its absolute position, leading to rendering errors. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: vivante_fill() takes the boxes themselves rather than the regionRussell King
Arrange for vivante_fill() to take the clip box and a list of boxes to operate on, rather than a region. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-09-12vivante: fix Composite repeat handlingRussell King
We should change the Picture's repeat setting across a Composite operation. Ensure that this is restored after we've done processing the operation. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-26vivante: fix buggy error path when mapping non-shmem bosRussell King
We were freeing the vivante_pixmap structure, but were then going on to store a pointer to it - this is not what was intended. Ensure that we mark the pixmap as being without a vivante_pixmap structure. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-14packaging: only include *_drv.so objects in base packageRussell King
Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-14vivante: use xf86ScreenToScrn(pScreen)Russell King
Use xf86ScreenToScrn(pScreen) rather than directly converting via xf86Screens. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-14src: use xf86ScreenToScrn(pScreen)Russell King
Use xf86ScreenToScrn(pScreen) rather than directly converting via xf86Screens. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-14src: avoid passing the Armada buffer manager for non-Armada hardwareRussell King
Avoid passing the Armada buffer manager into the acceleration backend when we are not using the Armada-DRM kernel driver. The Armada buffer manager relies on some private IOCTLs which are not implemented by other driveres. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-14vivante: avoid assert() in prepare_cpu_drawable()Russell King
The same pixmap may be used multiple times in the unaccelerated functions. Do not require the in-use counter to be zero when preparing it. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-03vivante: fix overlapping operationsRussell King
Where the 2D engine has multiple pixel pipes, it is possible for two GPU operations to overlap and operate concurrently. If this occurs with an overlapping blit copy, one copying to the scanout buffer, and another copying from the scanout buffer, it results in corrupted pixel data read from the scanout buffer. This happens when software cursor mode is enabled with a GC320, as is the case with iMX6Q SoCs. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-08-02vivante: include alpha channel in pixmapsRussell King
Always include the alpha channel in pixmap operations. This required as the blit can be used to upload images to the pixmaps which back a Xrender picture, where the alpha channel must be preserved, and because the 2D PE2.0 engine will avoid copying those bits. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-23Add vivante support for blending alpha-only solid masksRussell King
We can blend alpha-only solid masks in PictOpOver mode by using the Vivante GPU's global alpha mode, and instead performing an ATop operation. Gnome uses this when fading between two images, so this is a useful operation to accelerate. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-23Clean up vivante_accel_Composite() a littleRussell King
Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-23Add support for imx-drmRussell King
Add support for attaching to the imx-drm kernel module, thus allowing the driver to be used on iMX hardware as well. It should be noted that the libGAL backend does not support iMX, and so should be manually disabled in the Xorg config file. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-23Allocate Xv BOs using 16-bpp allocationsRussell King
Use 16-bpp BO allocations to allocate Xv display buffers, rather than 32-bpp and tweaking the height appropriately. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-23Fix bug in vivante pixmap dumping functionsRussell King
The vivante pixmap functions we not restoring the mapping state of the pixmap correctly. Fix this. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-19Fix FillSpans positioning bugRussell King
FillSpans included the drawable x/y coordinates. This is not necessary as the GC has miTranslate set, which ensures that we receive pre- translated coordinates here. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-07-15Fix CloseScreen bug in src/common_drm.cRussell King
Fix another server segfault when shutting down due to incorrect shutdown ordering. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-05-10Move compat-api.h headerRussell King
Building on Ubuntu 14.04 fails because the compat-api header is included too early. Fix these build errors. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-21Fix bail out on pictures we don't yet handle in composite methodRussell King
It is better to bail out early on pictures we don't handle than to try to handle them and then fail. We check: - the operation is one we can support - the source and destinations do not have alpha maps - the source has a drawable, or is a solid single coloured surface - the mask does not have an alpha map, and is not component alpha - the mask has a drawable The last case was missed, and this causes Audacious to crash when using the GTK+ theme. Bug reported by Matthew Coburn. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-21Split out the final blending operationRussell King
Move the final composite blend operation out into a separate function to allow it's re-use with other code paths. This permits some future optimisations to the composite operations. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Use compat-api.h for glyphsRussell King
We are duplicating this logic in vivante_unaccel_render.c - remove this and use the compat-api.h provided version. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Split out the ioctl issuing functionRussell King
This functionality can be re-used by providing other ioctls, so move it out from vivante_map_bo_to_gpu(). Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Move owner checking into vivante_map_gpu()Russell King
Move the pixmap owner checking into vivante_map_gpu(), which is where the ownership is switched. This helps to keep all that logic localised. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Disable vivante batch processingRussell King
With modern kernel drivers, there is no need to implement batching; this is only necessary if the kernel driver is buggy and allows the commit-with-stall to return before the pending operations have been completed. This allows removal of the batch code; however, keeping the batch code around is wise should the bug reappear in later code drops. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Tidy up commented out gcoHAL_Commit() and indentationRussell King
Tidy up the code a little by removing these unnecessary calls to gcoHAL_Commit(), and fix the indentation in vivante_fill(). Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Ensure DRI2 is closed down at the right pointRussell King
DRI2 is initialised before we hook the accelerator functions into the screen, so closing down DRI2 should happen after these functions have been unhooked from the screen for proper symmetry. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Rename map_dma_buf -> dmabuf_mapRussell King
This gives it a better namespace. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Move GPU source programming into gal_prepare_gpu()Russell King
We don't need to replicate this in every function, we can just do this when preparing the vivante pixmap for GPU access - but currently only for the non-blended operations. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2014-03-20Move Picture format into vivante_pixmapRussell King
Rather than carrying this around as a separate variable, store it in the vivante_pixmap structure so it follows the pixmap around. This ensures we have a consistent set of metadata about the image stored in the pixmap. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2013-12-23Fix segfault on X shutdown.Russell King
Freeing the vivante-held information on the screen pixmap after the vivante acceleration backend leads to a segfault in the GALCORE libraries. Avoid this by ensuring that this is done before the backend is shutdown. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2013-12-23Avoid bouncing pixmaps between GPU and CPU on ChangeWindowAttributes()Russell King
Avoid unnecessary bouncing of pixmaps between the GPU and CPU when ChangeWindowAttributes() is called. We don't need to map this to the CPU unless we're actually need to access the pixmap; merely checking for the flags is insufficient. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
2013-12-05Remove old/obsolete ioctlsRussell King
The mainline kernel will never support these old obsolete ioctls as it has more generic implementations for these. Remove them. Signed-off-by: Russell King <rmk@arm.linux.org.uk>
