2017-01-26drm: Silence the compiler for drm_mode_get_hv_timings()Chris Wilson1-2/+1
Since moving drm_crtc_get_hv_timings() into drm_modes.c, the compiler has been able to get smarter and spots that drm_mode_copy() is trying to preserve garbage from the stack.

2017-01-26drm: mali-dp: fix stride setting for multi-plane formatsMihail Atanassov4-10/+50
Hardware has multiple (2 or 3, depending on model) stride registers per layer; add a function that correctly takes that into account. On hardware that only has 2 stride registers, ensure that 3-plane (YUV) content has identical strides for both chroma planes.

2017-01-26drm/i915: Pevent copying uninitialised garbage into vma->ggtt_viewChris Wilson1-1/+1
Since tweaking i915_vma_compare() we allowed constructors to skip clearing the ggtt_view believing that we didn't access the unused members. That, as it turns out, was not entirely true. In particular, i915_gem_fault() uses ret = remap_io_mapping(area, area->vm_start + (vma->ggtt_view.partial.offset << PAGE_SHIFT), (ggtt->mappable_base + vma->node.start) >> PAGE_SHIFT, min_t(u64, vma->size, area->vm_end - area->vm_start), &ggtt->mappable); i.e. the ggtt_view.partial for both normal and partial views. If we allowed garbage into the normal vma->ggtt_view and then try userspace tried to mmap it, we could explode in an unobvious fashion.

As a simple workaround for the warning, we can pass a pointer to the data that we actually want to read into. This is not needed here, but also harmless, and lets the compiler know that the access is ok.

2017-01-25memory_hotplug: make zone_can_shift() return a boolean valueYasuaki Ishimatsu1-2/+2
online_{kernel|movable} is used to change the memory zone to ZONE_{NORMAL|MOVABLE} and online the memory. To check that memory zone can be changed, zone_can_shift() is used. Currently the function returns minus integer value, plus integer value and 0. When the function returns minus or plus integer value, it means that the memory zone can be changed to ZONE_{NORNAL|MOVABLE}. But when the function returns 0, there are two meanings. One of the meanings is that the memory zone does not need to be changed. For example, when memory is in ZONE_NORMAL and onlined by online_kernel the memory zone does not need to be changed. Another meaning is that the memory zone cannot be changed. When memory is in ZONE_NORMAL and onlined by online_movable, the memory zone may not be changed to ZONE_MOVALBE due to memory online limitation(see Documentation/memory-hotplug.txt). In this case, memory must not be onlined. The patch changes the return type of zone_can_shift() so that memory online operation fails when memory zone cannot be changed as follows: Before applying patch: # grep -A 35 "Node 2" /proc/zoneinfo Node 2, zone Normal <snip> node_scanned 0 spanned 8388608 present 7864320 managed 7864320 # echo online_movable > memory4097/state # grep -A 35 "Node 2" /proc/zoneinfo Node 2, zone Normal <snip> node_scanned 0 spanned 8388608 present 8388608 managed 8388608 online_movable operation succeeded. But memory is onlined as ZONE_NORMAL, not ZONE_MOVABLE. After applying patch: # grep -A 35 "Node 2" /proc/zoneinfo Node 2, zone Normal <snip> node_scanned 0 spanned 8388608 present 7864320 managed 7864320 # echo online_movable > memory4097/state bash: echo: write error: Invalid argument # grep -A 35 "Node 2" /proc/zoneinfo Node 2, zone Normal <snip> node_scanned 0 spanned 8388608 present 7864320 managed 7864320 online_movable operation failed because of failure of changing the memory zone from ZONE_NORMAL to ZONE_MOVABLE Fixes: df429ac03936 ("memory-hotplug: more general validation of zone during online") Link: http://lkml.kernel.org/r/2f9c3837-33d7-b6e5-59c0-6ca4372b2d84@gmail.com Signed-off-by: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com> Reviewed-by: Reza Arbab <arbab@linux.vnet.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This then requires the vring code to use the DMA API to establish translations, otherwise all transactions will result in fatal faults and termination. Given that ARM-based systems only see an SMMU if one is really present (the topology is all described by firmware tables such as device-tree or IORT), then we can safely use the DMA API for all legacy virtio devices. Modern devices can advertise the prescense of an IOMMU using the VIRTIO_F_IOMMU_PLATFORM feature flag. Cc: Andy Lutomirski <luto@kernel.org> Cc: Michael S.

2017-01-24drm: bridge: dw-hdmi: fix building without CONFIG_OFArnd Bergmann1-0/+2
The of_node member in struct drm_bridge is hidden when CONFIG_OF is disabled, causing a build error: drivers/gpu/drm/bridge/dw-hdmi.c: In function '__dw_hdmi_probe': drivers/gpu/drm/bridge/dw-hdmi.c:2063:14: error: 'struct drm_bridge' has no member named 'of_node' We could fix this either using a Kconfig dependency on CONFIG_OF or making the one line conditional. The latter gives us better compile test coverage, so this is what I'm doing here.

2017-01-23drm: mali-dp: Fix destination size handling when rotatingBrian Starkey1-7/+2
The destination rectangle provided by userspace in the CRTC_X/Y/W/H properties is already expressed as the dimensions after rotation. This means we shouldn't swap the width and height ourselves when a 90/270 degree rotation is requested, so remove the code doing the swap.

2017-01-23drm: mali-dp: Don't force source size == crtc sizeBrian Starkey1-2/+1
Remove the check enforcing that src_w and src_h match crtc_w and crtc_h, as this prevents rotation from working. The check was intended to disallow scaling, but drm_plane_helper_check_state() does that for us, while also taking rotation into account, so the removed check was redundant in any case.
