951c63bc3a In sun4v, use the sparc64 version. We haven't used the serial port on
sun4v yet, so this is a 'best-guess'.

7486916426 Add a .PATH entry to search for sources in the ${MACHINE}/${MACHINE}
directory before the ${MACHINE_ARCH}/${MACHINE_ARCH} directory so that
machine-specific files take precedence of architecture-specific ones.

This fixes the build on sun4v which doesn't use the sparc64 version
of mem.c.

b0bf75c83c file == NULL:
Issue __sflush() before possible setting O_APPEND mode or ftruncate(),
write to wrong place may occurse oserwise.
Use simplified _sseek() to the start, if no O_APPEND is set, instead
of _fseeko() (_sseek() to the end, if O_APPEND, occurse later, as for
file != NULL).
Don't check seek error return, as original fopen() and freopen() never
does.

file != NULL:
Add missing _sseek() to the end.

7d0ed28d3b Improve cleartmp in a number of aspects:
+ Use rc.subr(8) features properly.
+ Do the whole job of obliterating /tmp contents in find(1).
+ Leave lost+found and quota.{user,group} in /tmp only if root-owned.
+ Make the overall structure clearer by first removing the X dirs
  (perhaps along with the rest of /tmp) and then re-creating them.
+ Use "find -exec rm -rf {} +" for efficiency: each rm instance gets
  a chance to kill as much files in /tmp as ARG_MAX permits.

c5a01a410c Overhaul the transmit and dma paths:
- Use bus_dmamap_load_mbuf_sg() to eliminate the need for the callback and
all of the extra bookkeeping associated with it.
- Eliminate the bce_dmamap_arg structure and streamline the memory allocation
routines to not need it.  This does change some of the debugging messages.
- Refactor the loop that fills the buffer descriptor so that it can be done
with a single set of logic in a single loop instead of two sets of logic.
- Eliminate the need to cache and pass descriptor indexes between the start
loop and the encap function.
- Change the start loop to always check the ifnet sendq for more work.

This significantly helps the driver withstand large UDP workloads, though
it's still not perfect.  I suspect the remaining work lies with handling
the OACTIVE flag, and also in possibly streamlining the interrupt handler
some.  It is, however, nearly on par with the other popular gigabit drivers
in terms of stability now.

95f2da66d3 regen (linux AIO stuff) 2006-10-15 14:24:10 +00:00
Alexander Leidinger
6a1162d4cd 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

1. Linux kernel source code:   http://www.kernel.org/pub/linux/kernel/v2.6/

2. Linux manual pages:         http://www.kernel.org/pub/linux/docs/manpages/
   (io_setup(2), io_destroy(2), io_getevents(2), io_submit(2), io_cancel(2))

4. The package libaio, both source and binary:
       http://rpmfind.net/linux/rpm2html/search.php?query=libaio
   Simple transparent interface to Linux AIO system calls.

5. Libaio-oracle:              http://oss.oracle.com/projects/libaio-oracle/
   POSIX AIO implementation based on Linux AIO system calls (depending on
   libaio).

7e2393ff51 Long ago, revision 1.22 of vm/vm_pager.h introduced a bug. Specifically,
it introduced a check after the call to file system's get pages method
that assumes that the get pages method does not change the array of pages
that is passed to it.  In the case of vnode_pager_generic_getpages(),
this assumption has been incorrect.  The contents of the array of pages
may be shifted by vnode_pager_generic_getpages().  Likely, the problem
has been hidden by vnode_pager_haspage() limiting the set of pages that
are passed to vnode_pager_generic_getpages() such that a shift never
occurs.

The fix implemented herein is to adjust the pointer to the array of pages
rather than shifting the pages within the array.
