2017-10-19drm/vc4: Add the DRM_IOCTL_VC4_GEM_MADVISE ioctlBoris Brezillon
This ioctl will allow us to purge inactive userspace buffers when the system is running out of contiguous memory. For now, the purge logic is rather dumb in that it does not try to release only the amount of BO needed to meet the last CMA alloc request but instead purges all objects placed in the purgeable pool as soon as we experience a CMA allocation failure. Note that the in-kernel BO cache is always purged before the purgeable cache because those objects are known to be unused while objects marked as purgeable by a userspace application/library might have to be restored when they are marked back as unpurgeable, which can be expensive.

2017-10-19drivers: flag buses which demand DMA configurationRobin Murphy
We do not want the common dma_configure() pathway to apply indiscriminately to all devices, since there are plenty of buses which do not have DMA capability, and if their child devices were used for DMA API calls it would only be indicative of a driver bug. However, there are a number of buses for which DMA is implicitly expected even when not described by firmware - those we whitelist with an automatic opt-in to dma_configure(), assuming that the DMA address space and the physical address space are equivalent if not otherwise specified. Commit 723288836628 ("of: restrict DMA configuration") introduced a short-term fix by comparing explicit bus types, but this approach is far from pretty, doesn't scale well, and fails to cope at all with bus drivers which may be built as modules, like host1x. Let's refine things by making that opt-in a property of the bus type, which neatly addresses those problems and lets the decision of whether firmware description of DMA capability should be optional or mandatory stay internal to the bus drivers themselves.

2017-10-19drm/i915: Centralize the SKL DDI A/E vs. B/C/D buf trans handlingVille Syrjälä
SKL DDI B/C/D only have 9 usable buf trans registers for DP/eDP. That matches the normal DP buf trans tables, but the low vswing eDP tables have 10 entries. Thus the eDP tables can only be used safely with DDI A and E. We try to catch cases where DDI B/C/D gets used with the wrong number of entires in some parts of the code, but not everywhere. Let's move the code to deal with that deeper into intel_ddi_get_buf_trans_edp(). And for sake of symmetry do the same in intel_ddi_get_buf_trans_dp(). That would also avoid explosions in the rather unlikely case that the DP tables would get revised to 10 entries as well.
