2018-01-31drm/i915/icl: NV12 y-plane ddb is not in same planeMahesh Kumar1-2/+4
We don't have planar pixel format support implemented for ICL yet. ICL require 2 display planes to be allocated for Planar formats unlike previous GEN. So ICL/GEN11 doesn't require to write Y-plane ddb data in NV12_BUF_CFG register and PLANE_NV12_BUF_CFG register is removed in ICL. This patch removes the PLANE_NV12_BUF_CFG write for ICL.

2018-01-31drm/i915/icl: Do not fix dbuf block size to 512Mahesh Kumar2-7/+18
GEN9/10 had fixed DBuf block size of 512. Dbuf block size is not a fixed number anymore in GEN11, it varies according to bits per pixel and tiling. If 8bpp & Yf-tile surface, block size = 256 else block size = 512 This patch addresses the same. v2 (from Paulo): - Make it compile. - Fix a few coding style issues. v3: - Rebase on top of upstream patches v4 (from Paulo): - Bikeshed if statements (James).

2018-01-31PCI: cadence: Add EndPoint Controller driver for Cadence PCIe controllerCyrille Pitchen10-74/+825
This patch adds support to the Cadence PCIe controller in endpoint mode. Since pieces of source code are shared with the host driver (Root Complex mode), we create a new directory under drivers/pci dedicated to the Cadence PCIe controller. The common code is placed into drivers/pci/cadence/pcie-cadence.c and used by both the host and endpoint controller drivers.

Clean up drivers/Makefile by moving the pci/endpoint and pci/dwc entries from drivers/Makefile into drivers/pci/Makefile. Since we don't want to introduce any dependency between CONFIG_PCI and CONFIG_PCI_ENDPOINT, we now always execute drivers/pci/Makefile. Hence all Makefiles in drivers/pci/ were updated accordingly so no file is compiled when CONFIG_PCI is not defined. Also, we add a comment to reinforce that EPC and EPF libraries must be initialized before their users. Hence built-in EPC drivers, such as those of Designware, are linked after the endpoint core libraries. Finally, we add another comment to explain why obj-y has been chosen instead of obj-$(CONFIG_PCIE_DW) to parse the dwc/ sub-folder.

2018-01-31drm/i915: Flush ggtt writes through the old fenced vma before changing fencesChris Wilson1-2/+6
This is a precautionary measure as I have no evidence to suggest we've hit a bug here (I was hoping this might explain gdg's odd behaviour, but alas), but given that we have a function to flush the ggtt writes it seems prudent to use it prior to changing the fence register. Due to the intrinsic nature of the GTT often operating as an independent mmio path, we should not just rely on the write to the fence acting as a full flush for GTT writes.

2018-01-31mmc: sdhci: Implement an SDHCI-specific bounce bufferLinus Walleij2-8/+159
The bounce buffer is gone from the MMC core, and now we found out that there are some (crippled) i.MX boards out there that have broken ADMA (cannot do scatter-gather), and also broken PIO so they must use SDMA. Closer examination shows a less significant slowdown also on SDMA-only capable Laptop hosts. SDMA sets down the number of segments to one, so that each segment gets turned into a singular request that ping-pongs to the block layer before the next request/segment is issued. Apparently it happens a lot that the block layer send requests that include a lot of physically discontiguous segments. My guess is that this phenomenon is coming from the file system. These devices that cannot handle scatterlists in hardware can see major benefits from a DMA-contiguous bounce buffer. This patch accumulates those fragmented scatterlists in a physically contiguous bounce buffer so that we can issue bigger DMA data chunks to/from the card. When tested with a PCI-integrated host (1217:8221) that only supports SDMA: 0b:00.0 SD Host controller: O2 Micro, Inc.

2018-01-31drm/i915: Always run hangcheck while the GPU is busyChris Wilson4-21/+6
Previously, we relied on only running the hangcheck while somebody was waiting on the GPU, in order to minimise the amount of time hangcheck had to run. (If nobody was watching the GPU, nobody would notice if the GPU wasn't responding -- eventually somebody would care and so kick hangcheck into action.) However, this falls apart from around commit 4680816be336 ("drm/i915: Wait first for submission, before waiting for request completion"), as not all waiters declare themselves to hangcheck and so we could switch off hangcheck and miss GPU hangs even when waiting under the struct_mutex. If we enable hangcheck from the first request submission, and let it run until the GPU is idle again, we forgo all the complexity involved with only enabling around waiters. We just have to remember to be careful that we do not declare a GPU hang when idly waiting for the next request to be come ready, as we will run hangcheck continuously even when the engines are stalled waiting for external events. This should be true already as we should only be tracking requests submitted to hardware for execution as an indicator that the engine is busy.
