2012-05-17xhci: Add new short TX quirk for Fresco Logic host.Sarah Sharp
Sergio reported that when he recorded audio from a USB headset mic plugged into the USB 3.0 port on his ASUS N53SV-DH72, the audio sounded "robotic". When plugged into the USB 2.0 port under EHCI on the same laptop, the audio sounded fine. The device is: Bus 002 Device 004: ID 046d:0a0c Logitech, Inc. Clear Chat Comfort USB Headset The problem was tracked down to the Fresco Logic xHCI host controller not correctly reporting short transfers on isochronous IN endpoints. The driver would submit a 96 byte transfer, the device would only send 88 or 90 bytes, and the xHCI host would report the transfer had a "successful" completion code, with an untransferred buffer length of 8 or 6 bytes. The successful completion code and non-zero untransferred length is a contradiction. The xHCI host is supposed to only mark a transfer as successful if all the bytes are transferred. Otherwise, the transfer should be marked with a short packet completion code. Without the EHCI bus trace, we wouldn't know whether the xHCI driver should trust the completion code or the untransferred length. With it, we know to trust the untransferred length. Add a new xHCI quirk for the Fresco Logic host controller. If a transfer is reported as successful, but the untransferred length is non-zero, print a warning. For the Fresco Logic host, change the completion code to COMP_SHORT_TX and process the transfer like a short transfer. This should be backported to stable kernels that contain the commit f5182b4155b9d686c5540a6822486400e34ddd98 "xhci: Disable MSI for some Fresco Logic hosts." That commit was marked for stable kernels as old as 2.6.36.

2012-05-17ARM: 7419/1: vfp: fix VFP flushing regression on sigreturn pathWill Deacon
Commit ff9a184c ("ARM: 7400/1: vfp: clear fpscr length and stride bits on entry to sig handler") flushes the VFP state prior to entering a signal handler so that a VFP operation inside the handler will trap and force a restore of ABI-compliant registers. Reflushing and disabling VFP on the sigreturn path is predicated on the saved thread state indicating that VFP was used by the handler -- however for SMP platforms this is only set on context-switch, making the check unreliable and causing VFP register corruption in userspace since the register values are not necessarily those restored from the sigframe. This patch unconditionally flushes the VFP state after a signal handler. Since we already perform the flush before the handler and the flushing itself happens lazily, the redundant flush when VFP is not used by the handler is essentially a nop.

2012-05-17ARM: 7418/1: LPAE: fix access flag setup in mem_type_tableVitaly Andrianov
A zero value for prot_sect in the memory types table implies that section mappings should never be created for the memory type in question. This is checked for in alloc_init_section(). With LPAE, we set a bit to mask access flag faults for kernel mappings. This breaks the aforementioned (!prot_sect) check in alloc_init_section(). This patch fixes this bug by first checking for a non-zero prot_sect before setting the PMD_SECT_AF flag.

2012-05-17sched: Remove stale power aware scheduling remnants and dysfunctional knobsPeter Zijlstra
It's been broken forever (i.e. it's not scheduling in a power aware fashion), as reported by Suresh and others sending patches, and nobody cares enough to fix it properly ... so remove it to make space free for something better. There's various problems with the code as it stands today, first and foremost the user interface which is bound to topology levels and has multiple values per level. This results in a state explosion which the administrator or distro needs to master and almost nobody does. Furthermore large configuration state spaces aren't good, it means the thing doesn't just work right because it's either under so many impossibe to meet constraints, or even if there's an achievable state workloads have to be aware of it precisely and can never meet it for dynamic workloads. So pushing this kind of decision to user-space was a bad idea even with a single knob - it's exponentially worse with knobs on every node of the topology. There is a proposal to replace the user interface with a single 3 state knob: sched_balance_policy := { performance, power, auto } where 'auto' would be the preferred default which looks at things like Battery/AC mode and possible cpufreq state or whatever the hw exposes to show us power use expectations - but there's been no progress on it in the past many months. Aside from that, the actual implementation of the various knobs is known to be broken. There have been sporadic attempts at fixing things but these always stop short of reaching a mergable state. Therefore this wholesale removal with the hopes of spurring people who care to come forward once again and work on a coherent replacement.

2012-05-17e1000: remove workaround for Errata 23 from jumbo allocSebastian Andrzej Siewior
According to the comment, errata 23 says that the memory we allocate can't cross a 64KiB boundary. In case of jumbo frames we allocate complete pages which can never cross the 64KiB boundary because PAGE_SIZE should be a multiple of 64KiB so we stop either before the boundary or start after it but never cross it. Furthermore the check seems bogus because it looks at skb->data which is not seen by the HW at all because we only pass the DMA address of the page we allocated. So I *think* the workaround is not required here.

2012-05-17drm/exynos: add G2D driverJoonyoung Shim
Changelog v3: - use __u64 instead of pointer in ioctl struct. The G2D is a 2D graphic accelerator that supports Bit Block Transfer. This G2D driver is exynos drm specific and supports only G2D(version 4.1) of later Exynos series from Exynos4X12 because supporting DMA. The G2D is performed by two tasks simply. 1. Configures the rendering parameters, such as foreground color and coordinates data by setting the drawing context registers. 2. Start the rendering process by setting thre relevant command registers accordingly. The G2D version 4.1 supports DMA mode as host interface. User can make command list to reduce HOST(ARM) loads. The contents of The command list is setted to relevant registers of G2D by DMA. The command list is composed Header and command sets and Tail. - Header: The number of command set(4Bytes) - Command set: Register offset(4Bytes) + Register data(4Bytes) - Tail: Pointer of base address of the other command list(4Bytes) By Tail field, the G2D can process many command lists without halt at one go. The G2D has following the rendering pipeline. --> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling --> Color Key --> ROP --> Mask Operation --> Alpha Blending --> Dithering --> FrameBuffer And supports various operations from the rendering pipeline. - copy - fast solid color fill - window clipping - rotation - flip - 4 operand raster operation(ROP4) - masking operation - alpha blending - color key - dithering - etc User should make the command list to data and registers needed by operation to use. The Exynos G2D driver only manages the command lists received from user. Some registers needs memory base address(physical address) of image. User doesn't know its physical address, so fills the gem handle of that memory than address to command sets, then G2D driver converts it to memory base address. We adds three ioctls and one event for Exynos G2D. - ioctls DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver - event DRM_EXYNOS_G2D_EVENT: event to give notification completion of the command list to user Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2012-05-17drm/exynos: added vp scaling feature for hdmiSeung-Woo Kim
This patch adds vp scaling feature for exynos hdmi. Scaling ratio between source and destination is used for width and height. Also meaningless variables to set registers are cleaned.

2012-05-17drm/exynos: added source size to overlay structureSeung-Woo Kim
Set plane has source size but exynos overlay structure did not consider it. This patch adds source size to overlay structure. For set crtc, source size is set from crtc size.
