config_drive:
Catch an instance of anonymous drives. Doubtless many remain.
interrupt.c:
complete_rqe:
Call logrq to log iodone events if DEBUG_LASTREQS is set.
Call set_sd_state with setstate_noupdate to avoid buffered I/O out
of interrupt context.
Use define DEBUG_RESID instead of constant.
memory.c:
Remove dead expandrq() function
Malloc:
Remove directory component of file names in malloc table.
Add function vinum_rqinfo (part of the request tracing stuff).
request.c:
Add function logrq (part of the request tracing stuff).
vinumstrategy:
Check whether config needs to be written to disk, do it if so.
This is a stopgap until the Vinum daemon (bacchusd? oenologistd?)
is written.
If DEBUG_LASTREQS is set, call logrq to log user buffer headers.
launch_requests:
Correct format of debug output to console.
If DEBUG_LASTREQS is set, call logrq to log request elements.
request.h:
Add definitions for request trace.
state.c:
set_sd_state:
Check flags for setstate_noupdate. If set, don't write the config
to disk, just set global VF_DIRTYCONFIG flag. This is part of the
kludge to avoid writing config from an interrupt context.
vinumext.h:
Add declaration for vinum_rqinfo, put inside #ifdef DEBUG
Remove dead macro expandrq
vinumio.h:
Increase maximum ioctl reply length to 4 kB if DEBUG is set.
Define VINUM_RQINFO ioctl if DEBUG is set.
vinumioctl.c:
vinumioctl:
Change implementation of VINUM_DEBUG ioctl: use a debug flag
(DEBUG_REMOTEGDB) to decide whether to go into remote debugging or
not.
Implement VINUM_RQINFO.
vinumkw.h:
Define kw_info even when not debugging.
vinumvar.h:
Define VF_DIRTYCONFIG
Add pointers to request info to vinum_info if DEBUG is set.
Define setstate_noupdate
Define additional debug bits DEBUG_RESID, DEBUG_LASTREQS and
DEBUG_REMOTEGDB.
agressive. With the old code, if a descriptor chain was already on its
way to the chip, xl_start() would try to splice new chains onto the end
of the current chain by stopping the transmitter, modifying the tail
pointer of the current chain to point to the head of the new chain, then
restart the transmitter. The manual says you're allowed to do this and
it works, but I'm not too keen on it anymore.
The new code waits until the eixsting chain has been sent and then
queues the next waiting chain in the 'transmit ok' handler.
Performance still looks good one way or the other.
Alpha. This is a minor, but important distinction. Should be a no-op
to the install base. If OBJFORMAT is set elsewhere, things work
exactly as they did before.
RealTek 8129/8139 chipset like I've been threatening. Update kernel
configs, userconfig.c, relnotes and sysinstall. No man page yet;
comming soon.
I consider this driver stable enough that I want to give it some
exposure in -current.
- Use the system headers method for Elf32/Elf64 symbol compatability
- get rid of the UPRINTF debugging.
- check the ELF header for compatability much more completely
- optimize the section mapper. Use the same direct VM interfaces that
imgact_aout.c and kern_exec.c use.
- Check the return codes from the vm_* functions better. Some return
KERN_* results, not an errno.
- prefault the page tables to reduce startup faults on page tables like
a.out does.
- reset the segment protection to zero for each loop, otherwise each
segment could get progressively more privs. (eg: if the first was
read/write/execute, and the second was meant to be read/execute, the
bug would make the second r/w/x too. In practice this was not a
problem because executables are normally laid out with text first.)
- Don't impose arbitary limits. Use the limits on headers imposed by
the need to fit them into one page.
- Remove unused switch() cases now that the verbose debugging is gone.
I've been using an earlier version of this for a month or so.
This sped up ELF exec speed a bit for me but I found it hard to get
consistant benchmarks when I tested it last (a few weeks ago).
I'm still bothered by the page read out of order caused by the
transition from data to bss. This which requires either part filling the
transition page or clearing the remainder.
Move the initialization before isa_configure() and npx, in case npx does
something to initialize the state of the emulator somehow.
I do not have any machines without a FPU so that I can test this with -
except an old 386sx motherboard in a box somewhere that might work...
Supply the moduledata handle rather than the event dispatcher function.
This should explain the panic on boot problem that's been discussed in
-current at the moment. Both machines had GNU_MATH_EMULATE.
breaks cross-builds. Just depend on ${.CURDIR}/../sys/conf/newvers.sh
existing.
Don't override the (correct) defaults for the depend, lint or tags target.
In LDIRS: fixed order-rot. Don't comment out dead networking directories;
remove them.
checkdpadd, lint, maninstall, objlink, regress and tags.
Removed bogus user target cleanobj. It is the non-recursive base of
the cleandir target, so it is not useful (or usable) here.
