2017-01-10r8152: fix rx issue for runtime suspendhayeswang
Pause the rx and make sure the rx fifo is empty when the autosuspend occurs. If the rx data comes when the driver is canceling the rx urb, the host controller would stop getting the data from the device and continue it after next rx urb is submitted. That is, one continuing data is split into two different urb buffers. That let the driver take the data as a rx descriptor, and unexpected behavior happens.

2017-01-10target: use XCOPY segment descriptor CSCD IDsDavid Disseldorp
The XCOPY specification in SPC4r37 states that the XCOPY source and destination device(s) should be derived from the copy source and copy destination (CSCD) descriptor IDs in the XCOPY segment descriptor. The CSCD IDs are generally (for block -> block copies), indexes into the corresponding CSCD descriptor list, e.g. ================================= EXTENDED COPY Header ================================= CSCD Descriptor List - entry 0 + LU ID <--------------<------------------\ - entry 1 | + LU ID <______________<_____________ | ================================= | | Segment Descriptor List | | - segment 0 | | + src CSCD ID = 0 --------->---------+----/ + dest CSCD ID = 1 ___________>______| + len + src lba + dest lba ================================= Currently LIO completely ignores the src and dest CSCD IDs in the Segment Descriptor List, and instead assumes that the first entry in the CSCD list corresponds to the source, and the second to the destination. This commit removes this assumption, by ensuring that the Segment Descriptor List is parsed prior to processing the CSCD Descriptor List. CSCD Descriptor List processing is modified to compare the current list index with the previously obtained src and dest CSCD IDs. Additionally, XCOPY requests where the src and dest CSCD IDs refer to the CSCD Descriptor List entry can now be successfully processed.

2017-01-10drm/i915: Use new CRC debugfs APITomeu Vizoso
The core provides now an ABI to userspace for generation of frame CRCs, so implement the ->set_crc_source() callback and reuse as much code as possible with the previous ABI implementation. When handling the pageflip interrupt, we skip 1 or 2 frames depending on the HW because they contain wrong values. For the legacy ABI for generating frame CRCs, this was done in userspace but now that we have a generic ABI it's better if it's not exposed by the kernel. v2: - Leave the legacy implementation in place as the ABI implementation in the core is incompatible with it. v3: - Use the "cooked" vblank counter so we have a whole 32 bits. - Make sure we don't mess with the state of the legacy CRC capture ABI implementation. v4: - Keep use of get_vblank_counter as in the legacy code, will be changed in a followup commit. v5: - Skip first frame or two as it's known that they contain wrong data. - A few fixes suggested by Emil Velikov. v6: - Rework programming of the HW registers to preserve previous behavior. v7: - Address whitespace issue. - Added a comment on why in the implementation of the new ABI we skip the 1st or 2nd frames. v9: - Add stub for intel_crtc_set_crc_source. v12: - Rebased. - Remove stub for intel_crtc_set_crc_source and instead set the callback to NULL (Jani Nikula). v15: - Rebased.

2017-01-10drm/i915: Remove the rounding down of the gen4+ fence regionChris Wilson
Restricting the fence to the end of the previous tile-row breaks access to the final portion of the object. On gen2/3 we employed lazy fencing to pad out the fence with scratch page to provide access to the tail, and now we also pad out the object on gen4+ we can apply the same fix.

2017-01-10drm/i915: Store required fence size/alignment for GGTT vmaChris Wilson
The fence size/alignment is a combination of the vma size plus object tiling parameters. Those parameters are rarely changed, making the fence size/alignemnt roughly constant for the lifetime of the VMA. We can simplify subsequent calculations by precalculating the size/alignment required for GGTT vma taking fencing into account (with an update if we do change the tiling or stride).

2017-01-10drm/i915: Replace WARNs in fence register writes with extensive assertsChris Wilson
All of these conditions are prechecked by i915_tiling_ok() before we allow setting the tiling/stride on the object and so we should never fail asserting those conditions before writing the register.

2017-01-10drm/i915: Align GGTT sizes to a fence tile rowChris Wilson
Ensure the view occupies the full tile row so that reads/writes into the VMA do not escape (via fenced detiling) into neighbouring objects - we will pad the object with scratch pages to satisfy the fence. This applies the lazy-tiling we employed on gen2/3 to gen4+.

2017-01-10dmaengine: omap-dma: Fix the port_window supportPeter Ujfalusi
We do not yet have users of port_window. The following errors were found when converting the tusb6010_omap.c musb driver: - The peripheral side must have SRC_/DST_PACKED disabled - when configuring the burst for the peripheral side the memory side configuration were overwritten: d->csdp = ... -> d->csdp |= ... - The EI and FI were configured for the wrong sides of the transfers. With these changes and the converted tus6010_omap.c I was able to verify that things are working as they expected to work.
