2016-04-19usb: gadget: f_fs: Fix EFAULT generation for async read operationsLars-Peter Clausen1-1/+1
In the current implementation functionfs generates a EFAULT for async read operations if the read buffer size is larger than the URB data size. Since a application does not necessarily know how much data the host side is going to send it typically supplies a buffer larger than the actual data, which will then result in a EFAULT error. This behaviour was introduced while refactoring the code to use iov_iter interface in commit c993c39b8639 ("gadget/function/f_fs.c: use put iov_iter into io_data"). The original code took the minimum over the URB size and the user buffer size and then attempted to copy that many bytes using copy_to_user(). If copy_to_user() could not copy all data a EFAULT error was generated. Restore the original behaviour by only generating a EFAULT error when the number of bytes copied is not the size of the URB and the target buffer has not been fully filled. Commit 342f39a6c8d3 ("usb: gadget: f_fs: fix check in read operation") already fixed the same problem for the synchronous read path.

2016-04-19usb: renesas_usbhs: use usb_gadget_{un}map_request_by_dev() for IPMMUYoshihiro Shimoda1-4/+2
The previous code could use the first USB-DMAC with IPMMU if iommus property was set into this device node. However, in this case, it could not control the second USB-DMAC with IPMMU because a parameter of IPMMU (micro-TLB id) is different with each USB-DMAC. So, this patch uses the usb_gadget_{un}map_request_by_dev() APIs for IPMMU. (Then, iommus property should be set into USB-DMAC node(s).)

previously we were using a maximum of 32 TRBs per endpoint. With each TRB being 16 bytes long, we were using 512 bytes of memory for each endpoint. However, SLAB/SLUB will always allocate PAGE_SIZE chunks. In order to better utilize the memory we allocate and to allow deeper queues for gadgets which would benefit from it (g_ether comes to mind), let's increase the maximum to 256 TRBs which rounds up to 4096 bytes for each endpoint.

2016-04-14usb: dwc3: gadget: always enable CSPFelipe Balbi1-7/+9
CSP bit of TRB Control is useful for protocols such CDC EEM/ECM/NCM where we're transferring in blocks of MTU-sized requests (usually MTU is 1500 bytes). We know we will always have a short packet after two (for HS) wMaxPacketSize packets and, usually, we will have a long(-ish) queue of requests (for our g_ether gadget, we have at least 10 requests). Instead of always stopping the queue processing to interrupt, giveback and restart, let's tell dwc3 to interrupt but continue processing following request if we have anything already pending in the queue. This gave me a considerable improvement of 40% on my test setup. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

I can't remember the exact size of default FIFO, but it was less than one bulk superspeed packet (<1024) which would prevent USB3 from ever working on OMAP5 ES1.0. However, OMAP5 ES1.0 support has been dropped by commit aa2f4b16f830 ("ARM: OMAP5: id: Remove ES1.0 support") which renders FIFO resizing unnecessary.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management and ACPI fixes from Rafael Wysocki: "Fixes for some issues discovered after recent changes and for some that have just been found lately regardless of those changes (intel_pstate, intel_idle, PM core, mailbox/pcc, turbostat) plus support for some new CPU models (intel_idle, Intel RAPL driver, turbostat) and documentation updates (intel_pstate, PM core). Specifics: - intel_pstate fixes for two issues exposed by the recent switch over from using timers and for one issue introduced during the 4.4 cycle plus new comments describing data structures used by the driver (Rafael Wysocki, Srinivas Pandruvada). - intel_idle fixes related to CPU offline/online (Richard Cochran). - intel_idle support (new CPU IDs and state definitions mostly) for Skylake-X and Kabylake processors (Len Brown). - PCC mailbox driver fix for an out-of-bounds memory access that may cause the kernel to panic() (Shanker Donthineni). - New (missing) CPU ID for one apparently overlooked Haswell model in the Intel RAPL power capping driver (Srinivas Pandruvada). - Fix for the PM core's wakeup IRQs framework to make it work after wakeup settings reconfiguration from sysfs (Grygorii Strashko). - Runtime PM documentation update to make it describe what needs to be done during device removal more precisely (Krzysztof Kozlowski). - Stale comment removal cleanup in the cpufreq-dt driver (Viresh Kumar). - turbostat utility fixes and support for Broxton, Skylake-X and Kabylake processors (Len Brown)" * tag 'pm+acpi-4.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (28 commits) PM / wakeirq: fix wakeirq setting after wakup re-configuration from sysfs tools/power turbostat: work around RC6 counter wrap tools/power turbostat: initial KBL support tools/power turbostat: initial SKX support tools/power turbostat: decode BXT TSC frequency via CPUID tools/power turbostat: initial BXT support tools/power turbostat: print IRTL MSRs tools/power turbostat: SGX state should print only if --debug intel_idle: Add KBL support intel_idle: Add SKX support intel_idle: Clean up all registered devices on exit. intel_idle: Propagate hot plug errors. intel_idle: Don't overreact to a cpuidle registration failure. intel_idle: Setup the timer broadcast only on successful driver load. intel_idle: Avoid a double free of the per-CPU data. intel_idle: Fix dangling registration on error path. intel_idle: Fix deallocation order on the driver exit path. intel_idle: Remove redundant initialization calls. intel_idle: Fix a helper function's return value. intel_idle: remove useless return from void function. ...
