2018-03-15drm/i915/gvt: Correct the privilege shadow batch buffer addressfred gao3-0/+20
Once the ring buffer is copied to ring_scan_buffer and scanned, the shadow batch buffer start address is only updated into ring_scan_buffer, not the real ring address allocated through intel_ring_begin in later copy_workload_to_ring_buffer. This patch is only to set the right shadow batch buffer address from Ring buffer, not include the shadow_wa_ctx. v2: - refine some comments. (Zhenyu) v3: - fix typo in title. (Zhenyu) v4: - remove the unnecessary comments. (Zhenyu) - add comments in bb_start_cmd_va update.

The race is horrible as it results from calling set-wedged on active HW (the GPU reset failed) and as such we need to be careful as the HW state changes beneath us. Fortunately, it's the same scary conditions as affect normal reset, so we can reuse the same machinery to disable state tracking as we clobber it.

2018-03-05drm/i915/perf: fix perf stream opening lockLionel Landwerlin1-27/+13
We're seeing on CI that some contexts don't have the programmed OA period timer that directs the OA unit on how often to write reports. The issue is that we're not holding the drm lock from when we edit the context images down to when we set the exclusive_stream variable. This leaves a window for the deferred context allocation to call i915_oa_init_reg_state() that will not program the expected OA timer value, because we haven't set the exclusive_stream yet. v2: Drop need_lock from gen8_configure_all_contexts() (Matt) Signed-off-by: Lionel Landwerlin <[email protected]> Reviewed-by: Matthew Auld <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Fixes: 701f8231a2f ("drm/i915/perf: prune OA configs") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102254 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103715 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103755 Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Cc: Jani Nikula <[email protected]> Cc: Joonas Lahtinen <[email protected]> Cc: Rodrigo Vivi <[email protected]> Cc: [email protected] Cc: <[email protected]> # v4.14+ (cherry picked from commit 41d3fdcd15d5ecf29cc73e8b79c2327ebb54b960) Signed-off-by: Rodrigo Vivi <[email protected]>

2018-03-02libnvdimm: re-enable deep flush for pmem devices via fsync()Dave Jiang1-2/+1
Re-enable deep flush so that users always have a way to be sure that a write makes it all the way out to media. Writes from the PMEM driver always arrive at the NVDIMM since movnt is used to bypass the cache, and the driver relies on the ADR (Asynchronous DRAM Refresh) mechanism to flush write buffers on power failure. The Deep Flush mechanism is there to explicitly write buffers to protect against (rare) ADR failure. This change prevents a regression in deep flush behavior so that applications can continue to depend on fsync() as a mechanism to trigger deep flush in the filesystem-DAX case.

2018-03-02vfio: disable filesystem-dax page pinningDan Williams1-3/+15
Filesystem-DAX is incompatible with 'longterm' page pinning. Without page cache indirection a DAX mapping maps filesystem blocks directly. This means that the filesystem must not modify a file's block map while any page in a mapping is pinned. In order to prevent the situation of userspace holding of filesystem operations indefinitely, disallow 'longterm' Filesystem-DAX mappings. RDMA has the same conflict and the plan there is to add a 'with lease' mechanism to allow the kernel to notify userspace that the mapping is being torn down for block-map maintenance. Perhaps something similar can be put in place for vfio. Note that xfs and ext4 still report: "DAX enabled. Warning: EXPERIMENTAL, use at your own risk" ...at mount time, and resolving the dax-dma-vs-truncate problem is one of the last hurdles to remove that designation.

2018-02-28xen-netfront: Fix hang on device removalJason Andryuk1-1/+6
A toolstack may delete the vif frontend and backend xenstore entries while xen-netfront is in the removal code path. In that case, the checks for xenbus_read_driver_state would return XenbusStateUnknown, and xennet_remove would hang indefinitely. This hang prevents system shutdown. xennet_remove must be able to handle XenbusStateUnknown, and netback_changed must also wake up the wake_queue for that state as well.

2018-02-28xen/pirq: fix error path cleanup when binding MSIsRoger Pau Monne1-2/+2
Current cleanup in the error path of xen_bind_pirq_msi_to_irq is wrong. First of all there's an off-by-one in the cleanup loop, which can lead to unbinding wrong IRQs. Secondly IRQs not bound won't be freed, thus leaking IRQ numbers. Note that there's no need to differentiate between bound and unbound IRQs when freeing them, __unbind_from_irq will deal with both of them correctly.
