2015-03-18intel: Export total subslice and EU countsJeff McGee
Update kernel interface with new I915_GETPARAM ioctl entries for subslice total and EU total. Add a wrapping function for each parameter. Userspace drivers need these values when constructing GPGPU commands. This kernel query method is intended to replace the PCI ID-based tables that userspace drivers currently maintain. The kernel driver can employ fuse register reads as needed to ensure the most accurate determination of GT config attributes. This first became important with Cherryview in which the config could differ between devices with the same PCI ID. The kernel detection of these values is device-specific. Userspace drivers should continue to maintain ID-based tables for older devices which return ENODEV when using this query. v2: remove unnecessary include of <stdbool.h> and increment the I915_GETPARAM indices to match updated kernel patch.

2015-03-17configure.ac: fix host_cpu/atomics detectionEmil Velikov
Previous code was busted, as it wasn't checking directly for what it was meant to, and at the end changing the user's selection if host_cpu heuristics were involved. Simplify things by adding a macro that does the long message printing for us, and check for only what we need. This fixes commit 36cff14bb03(configure: omap, freedreno and tegra require atomics) which incorrectly assumed that the code was working fine, and effectively made impossible to enable freedreno due to it's host_cpu detection.

AM_MAINTAINER_MODE can be used to disable generation of rebuild rules. This is not something we want to condone/support, considering it can cause greater problems than the perceived benefits. Additionally the Automake manual leans towards avoiding the use of AM_MAINTAINER_MODE. http://www.gnu.org/software/automake/manual/html_node/maintainer_002dmode.html Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>

2015-03-16exynos: honor the repeat mode in g2d_copy_with_scaleTobias Jakobi
This is useful when the default repeat mode, which is 'repeat' produces artifacts at the borders of the copied image. Choose the 'pad' mode to make use of the color of the destination image. In my usage case the destination is the framebuffer, which is solid filled with a background color. Scaling with 'pad' mode would then just do the right thing and also produces nice borders on the output.

2015-03-06Revert "intel: Fix documentation for drm_intel_gem_bo_wait()"Daniel Vetter
This reverts commit 080b4929b7452dc1fea32ac1d32e7e571e7fb38b. Chris noticed that "negative values wait forever" is indeed intended behaviour and the issue is just that we didn't have a testcase (fixed now) and that a regression slipped through (fixed and on track for all stable kernels). So lets undo the documentation change for consistency, since working around kernel regressions isn't good. Practical impact is nil anyway. v2: Add a note to docs that some kernels have been broken. v3: Remove the random garbage included by accident.
