ITC (Interrupt Threshold Control) is used to set the maximum rate at which the host/device controller will issue interrupts. The default value is 8 (1ms) for it. EHCI core will modify it to 1, but device mode keeps it as default value. In some use cases like Android ADB, it only has one usb request for each direction, and maximum payload data is only 4KB, so the speed is 4MB/s at most, it needs controller to trigger interrupt as fast as possible to increase the speed. The USB performance will be better if the interrupt can be triggered faster. Reduce ITC value is benefit for USB performance, but the interrupt number is increased at the same time, it may increase cpu utilization too. Most of use case cares about performance, but some may care about cpu utilization, so, we leave a platform interface for user. We set ITC as 1 (1 micro-frame) as default value which is aligned with ehci core default value. Signed-off-by: Peter Chen <peter.chen@freescale.com>

It is used to configure controller parameters according to platform data, like speed, stream mode, etc, both host and device's initialization need it, most of code are the same for both roles, with this new interface, it can reduce the duplicated code and be easy to maintain in future.

For i.mx platform, set ttctrl.ttha with non-zero value only affects sitd, and ehci core makes sure the schedule is not full when accepts new request, so it will not occur the transaction which will acorss the SoF. Signed-off-by: Peter Chen <peter.chen@freescale.com>

Peter Chen authored
The register of ttctrl.ttha describes like below: - Internal TT Hub Address Representation - RW - Default = 0000000b This field is used to match against the Hub Address field in QH & siTD to determine if the packet is routed to the internal TT for directly attached FS/LS devices. If the Hub Address in the QH or siTD does not match this address then the packet will be broadcast on the High Speed ports destined for a downstream High Speed hub with the address in the QH/siTD. In silicon RTL, this entry only affects QH and siTD, and the hub.addr at both QH and siTD are 0 in ehci core for chipidea (with hcd->has_tt = 1). So, for QH, if the "usage_tt" flag at RTL is 0, set CI_HDRC_SET_NON_ZERO_TTHA will not affect QH (with non-hs device); for siTD, set this flag will change remaining space requirement for the last transaction from 1023 bytes to 188 bytes, it can increase the number of transactions within one frame, ehci periodic schedule code will not queue the packet if the frame space is full, so it is safe to set this flag for siTD. With this flag, it can fix the problem Alan Stern reported below: http://www.spinics.net/lists/linux-usb/msg123125.html And may fix Michael Tessier's problem too. http://www.spinics.net/lists/linux-usb/msg118679.html CC: stern@rowland.harvard.edu CC: michael.tessier@axiontech.ca Signed-off-by: Peter Chen <peter.chen@freescale.com>

Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes for 4.2. No area does particularly stand out but we have a two unpleasant ones: - Kernel ptes are marked with a global bit which allows the kernel to share kernel TLB entries between all processes. For this to work both entries of an adjacent even/odd pte pair need to have the global bit set. There has been a subtle race in setting the other entry's global bit since ~ 2000 but it take particularly pathological workloads that essentially do mostly vmalloc/vfree to trigger this. This pull request fixes the 64-bit case but leaves the case of 32 bit CPUs with 64 bit ptes unsolved for now. The unfixed cases affect hardware that is not available in the field yet. - Instruction emulation requires loading instructions from user space but the current fast but simplistic approach will fail on pages that are PROT_EXEC but !PROT_READ. For this reason we temporarily do not permit this permission and will map pages with PROT_EXEC | PROT_READ.

This patch enables xhci driver to support SPC by handling Stopped - Short Packet event in transfer event path. If SPC = '1' and the stop endpoint command is executed, after a Short Packet condition has been detected, but before the end of the TD has been reached, (i.e. the TD is in progress for pipe), then a Transfer Event TRB with its Completion Code set to Stopped - Short Packet and its TRB Transfer Length set to value of the EDTLA shall be forced for the interrupted TRB, irrespective of whether its IOC or ISP flags are set. This Transfer Event TRB will precede the Command Completion Event TRB for the command, and is referred to as a Stopped Transfer Event.

If the Contiguous Frame ID Capability is supported (CFC = 1), then the xHC shall match the Frame ID in every Isoch TD with SIA = 0 against the Frame Index of the MFINDEX register. This rule ensures resynchronization of Isoch TDs even if some are dropped due to Missed Service Errors or Stopping the endpoint.

If we have a series of events from userpsace, with %fprs=FPRS_FEF, like follows: ETRAP ETRAP VIS_ENTRY(fprs=0x4) VIS_EXIT RTRAP (kernel FPU restore with fpu_saved=0x4) RTRAP We will not restore the user registers that were clobbered by the FPU using kernel code in the inner-most trap. Traps allocate FPU save slots in the thread struct, and FPU using sequences save the "dirty" FPU registers only. This works at the initial trap level because all of the registers get recorded into the top-level FPU save area, and we'll return to userspace with the FPU disabled so that any FPU use by the user will take an FPU disabled trap wherein we'll load the registers back up properly. But this is not how trap returns from kernel to kernel operate. The simplest fix for this bug is to always save all FPU register state for anything other than the top-most FPU save area. Getting rid of the optimized inner-slot FPU saving code ends up making VISEntryHalf degenerate into plain VISEntry. Longer term we need to do something smarter to reinstate the partial save optimizations. Perhaps the fundament error is having trap entry and exit allocate FPU save slots and restore register state. Instead, the VISEntry et al. calls should be doing that work. This bug is about two decades old. Reported-by: James Y Knight <jyknight@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
