* add test for aio poll and io_pgeteventsaio-pollChristoph Hellwig2018-01-161-0/+149
| | | | | Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* add support for io_pgeteventsChristoph Hellwig2018-01-167-4/+126
| | | | | | | | | | | | | | | | | | This is ppoll/pselect equivalent for io_getevents. It atomically executes the following sequence: sigset_t origmask; pthread_sigmask(SIG_SETMASK, &sigmask, &origmask); ret = io_getevents(ctx, min_nr, nr, events, timeout); pthread_sigmask(SIG_SETMASK, &origmask, NULL); And thus allows to safely mix aio and signals, especially together with IO_CMD_POLL. See the pselect(2) man page for a more detailed explanation.

* syscall: get rid of custom syscall implementationsyscall-refactorJeff Moyer2018-01-1211-892/+34
| | | | | | | | | | | | | | | | | | | | | | | | | Maintaining the custom system call code for each architecture is a burden. I'm not convinced that we have clobber registers correct, and at best, we are just duplicating work that has already been done by the glibc maintainers. I asked Ben what the reasoning was behind not just using syscall. This was his answer: The main issue was that glibc's pthreads implementation really sucked back during initial development and there was a use-case for having the io_XXX functions usable directly from clone()ed threads that didn't have all the glibc pthread state setup for per-cpu areas to handle per-thread errno. That made sense back then, but is rather silly today. This patch gets rid of the architecture specific system call wrappers in favor of using syscall(). We leave the per-arch header files with the syscall numbers because we'll be adding a new system call soon, and this will allow us to add the new number without requiring newer kernels on build servers.

* syscall-generic: don't overwrite errnoJeff Moyer2018-01-121-4/+10

* Add support for preadv2/pwritev2Jeff Moyer2017-12-142-1/+203
| | | | | | | | | | | preadv2 and pwritev2 allow the caller to specify per-io flags. The main driver for this support in libaio is RWF_NOWAIT, which allows applications to specify that they don't want the submission thread to block waiting for things such as page cache invalidation, block instantiation, etc. This should help reduce unexpected latencies in the submission path.

* Add in ARM architecture support.libaio-0.3.108Jeff Moyer2009-06-094-2/+135
| | | | | | | | | | | | | | This support was taken from the Debian package: http://patch-tracking.debian.net/patch/series/view/libaio/0.3.106-3/00_arches.patch Kedar Sovani tested this on the following processor: Processor : Feroceon 88FR571-vd rev 0 (v5l) by running the libaio test harness. All tests passed. I also ran the test harness on a qemu emulated system, and all tests that I could run passed. Due to a bug in qemu, I could not configure a system with enough memory to run 2 of the tests. aio-dio-regress also passed testing on the emulated system.
* Instead of checking for __LP64__, the author of the test harnessJeff Moyer2009-06-091-2/+2
| | | | | | decided to check for __i386__ when deciding whether pointers should be 32 or 64 bits. I've fixed this so that the tests build and run properly on 32 bit platforms other than i386.

| | | | | | | like the previous entry, but that one fixed the __ia64_raw_syscall macro, located in syscall-ia64.h. This macro is in raw_syscall.c, which pretty much only exists for ia64. This bug prevented the package from building with newer version of gcc.

* Initial problem description:Jeff Moyer2005-08-011-0/+1
| | | | | | | | | | | | | | | | I have an application that optionally can use kernel async IO (libaio.so). As this is optional, I don't want to link the application with -laio, as otherwise all users have to install libaio RPM. Therefore, I'm loading libaio.so at runtime via dlopen(), and get the required function addresses via dlvsym(). Basically, I need io_queue_init(), io_submit(), and io_getevents(). This works fine on all supported platforms except IA64. It turns out the __ia64_raw_syscall macro did not include a .proc directive, which was causing this problem. The fix is to simply add a one line change to that macro.
