* [ath_hal] [ar9300] initial radar detection glue.Adrian Chadd2017-02-024-12/+29
| | | | | | | | | | | | | * flesh out a "get default DFS parameters" routine * remove the stub that returns NULL * fix up the enable DFS method to do what FreeBSD does - specifically, allow pe_enabled to be set/cleared. This allows the radar pulse reporting code to function, but it doesn't yet do anything useful. Notes: svn path=/head/; revision=313091
* Remake support for SMP kernel on UP cpu:Michal Meloun2017-02-0228-112/+129
| | | | | | | | | | | | | | | | | - Use new option SMP_ON_UP instead of (mis)using specific CPU type. By this, any SMP kernel can be compiled with SMP_ON_UP support. - Enable runtime detection of CPU multiprocessor extensions only if SMP_ON_UP option is used. In other cases (pure SMP or UP), statically compile only required variant. - Don't leak multiprocessor instructions to UP kernel. - Correctly handle data cache write back to point of unification. DCCMVAU is supported on all armv7 cpus. - For SMP_ON_UP kernels, detect proper TTB flags on runtime. Differential Revision: https://reviews.freebsd.org/D9133 Notes: svn path=/head/; revision=313090
* Remove remaining ifdefs from CESA headerWojciech Macek2017-02-021-6/+0
| | | | | | | | | | | | | | | Commit r312743 ("Use SoC ID - based detection in CESA") resulted in build failing for Marvell armv5 platforms, which don't support the newer version of CESA controller. This patch provides a fix by removing ifdefs around bitfields' definitions, so that they are known to all platforms.

Switch from retry loops (after the ggatec/dd write calls) to wait_for_ggate_device function calls after calling ggatec(8) instead to detect the presence of the /dev/ggate* device, as this function is sufficient for determining whether or not the character device is ready for testing While here, use atf_check consistently with all dd calls to ensure that data output is as expected.

* | [am335x] Fallback to standard video interface bindings when using Linux dtsOleksandr Tymoshenko2017-02-011-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically AM335x LCDC driver used non-standard "hdmi" property to refer to HDMI framer. There is no such thing in upstream DTS, so to handle both cases fallback to bindings described in bindings/media/video-interfaces.txt in Linux documentation. We still make some assumptions that are not universally true: we assume that if remote endpoint is available it's going to be HDMI framer. Which is true for AM335x-based devices currently supported but may be not true for some custom hardware. MFC after: 1 week Notes: svn path=/head/; revision=313068

FreeBSD and macOS do not have the `mallinfo` and `mallopt` functions, so normally these tests would fail, but when sanitizers are enabled, they incorrectly succeed, because the sanitizers define interceptors for these functions. This also applies to some other malloc-related functions, such as `memalign`, `pvalloc` and `cfree`. Fix this by not intercepting `mallinfo`, `mallopt`, `memalign`, `pvalloc` and `cfree` for FreeBSD and macOS, in all sanitizers. Also delete the non-functional `cfree` wrapper for Windows, to fix the test cases on that platform. Reviewers: emaste, kcc, rnk Subscribers: timurrrr, eugenis, hans, joerg, llvm-commits, kubamracek Differential Revision: https://reviews.llvm.org/D27654 This prevents autoconf scripts from incorrectly detecting that functions like mallinfo, mallopt, memalign, pvalloc and cfree are supported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The disk_* and part_* api is using 64bit values for media size and offsets. However, the current api is using off_t type, which is signed 64-bit int. In this context the signed media size does not make any sense, and the offsets are used to mark absolute, not relative locations. Also, the data from GPT partition table and some other sources is already using uint64_t data type, so using signed off_t can cause sign issues.

From Freescale's EREF reference manual this is enabled by a bit in HID0 and should otherwise default to traditional debug. However, none of the Freescale cores support that bit, and instead always use E.D. This results in kernel panics using the standard debug on e500mc+ cores. Enhanced debug allows debugging of interrupts, including critical interrupts, as it uses a different save/restore registers (srr*). At this time we don't use this ability, so instead share the core of the debug handler code between both handlers. MFC after: 3 weeks Notes: svn path=/head/; revision=313036

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The symbols currently hidden in libprofile_rt are needed for linking with `clang --coverage` to add coverage counters at link time and produce coverage numbers at runtime.

* | | Wait for /dev/ggate* to appear after calling `ggatel create` in ↵Enji Cooper2017-01-311-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | :ggatel_{file,md} The test assumed that `ggatel create` created a device on completion, but that's incorrect. This squashes the race by waiting for the device to appear, as `ggatel create` daemonizes before issuing an ioctl to geom_gate(4) if not called with `-v`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The desired behavior of atomic_fcmpset_() is to always exit on error. Instead of retrying on lost reservation, leave the retry to the caller, and return error. Reported by: kib Notes: svn path=/head/; revision=313007
* | | calculate_crc32c: Add SSE4.2 implementation on x86Conrad Meyer2017-01-317-1/+453
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Derived from an implementation by Mark Adler. The fast loop performs three simultaneous CRCs over subsets of the data before composing them. This takes advantage of certain properties of the CRC32 implementation in Intel hardware. (The CRC instruction takes 1 cycle but has 2-3 cycles of latency.) The CRC32 instruction does not manipulate FPU state. i386 does not have the crc32q instruction, so avoid it there. Otherwise the implementation is identical to amd64. Add basic userland tests to verify correctness on a variety of inputs.
