# $FreeBSD$
First incarnation of our Linux emulator or rather compatibility code. This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work.

Sample initial set of kld-ified modules. Not all have been completely converted yet. These are more of a starting point. This is NOT connected to the parent Makefile. OK'ed by jkh (who is ever so patiently waiting)

Backout the linux aio stuff. Several problems where identified and the dynamic nature (if no native aio code is available, the linux part returns ENOSYS because of missing requisites) should be solved differently than it is. All this will be done in P4. Not included in this commit is a backout of the changes to the native aio code (removing static in some places). Those changes (and some more) will also be needed when the reworked linux aio stuff will reenter the tree. Requested by: rwatson Discussed with: rwatson

MFP4 (with some minor changes): Implement the linux_io_* syscalls (AIO). They are only enabled if the native AIO code is available (either compiled in to the kernel or as a module) at the time the functions are used. If the AIO stuff is not available there will be a ENOSYS. From the submitter: ---snip--- DESIGN NOTES: 1. Linux permits a process to own multiple AIO queues (distinguished by "context"), but FreeBSD creates only one single AIO queue per process. My code maintains a request queue (STAILQ of queue(3)) per "context", and throws all AIO requests of all contexts owned by a process into the single FreeBSD per-process AIO queue. When the process calls io_destroy(2), io_getevents(2), io_submit(2) and io_cancel(2), my code can pick out requests owned by the specified context from the single FreeBSD per-process AIO queue according to the per-context request queues maintained by my code. 2. The request queue maintained by my code stores contrast information between Linux IO control blocks (struct linux_iocb) and FreeBSD IO control blocks (struct aiocb). FreeBSD IO control block actually exists in userland memory space, required by FreeBSD native aio_XXXXXX(2). 3. It is quite troubling that the function io_getevents() of libaio-0.3.105 needs to use Linux-specific "struct aio_ring", which is a partial mirror of context in user space. I would rather take the address of context in kernel as the context ID, but the io_getevents() of libaio forces me to take the address of the "ring" in user space as the context ID. To my surprise, one comment line in the file "io_getevents.c" of libaio-0.3.105 reads: Ben will hate me for this REFERENCE: 1. Linux kernel source code: http://www.kernel.org/pub/linux/kernel/v2.6/ (include/linux/aio_abi.h, fs/aio.c) 2.

Rather than using hidden includes (with cicular dependencies), directly include only the header files needed. This reduces the unneeded spamming of various headers into lots of files. For now, this leaves us with very few modules including vnet.h and thus needing to depend on opt_route.h. Reviewed by: brooks, gnn, des, zec, imp Sponsored by: The FreeBSD Foundation
