LINT: add a couple of new/missing/undocumented options
files.i386: add linux code so that you can compile a kernel with static
linux emulation ("options LINUX")
i386/*: use #if defined(COMPAT_LINUX) || defined(LINUX) to enable static
support of linux emulation (just like "IBCS2" makes ibcs2 static)
The main thing this is going to make obvious, is that the LINUX code
(when compiled from LINT) has a lot of warnings, some of which dont look
too pleasant..
is possible to boot a kernel with an empty in-core MFS image, and have
it load the image from floppy directly. This is admittedly a hack and
would be better replaced by a self-loading ram-disk.
all the other bt_XXX() functions in i386/scsi/bt*.
This the important effect of forcing a link error if the user is
still using the old "vector btintr" which is dangerously wrong
after Justin's updates to the driver.
The correct isa vector line for the bt driver is "vector bt_isa_intr".
Justin mentioned this in the commit message and updated LINT and
GENERIC. This change is to enforce that.. :-)
rpcgen-erated on the fly (just like librpcsvc).
Makefile: Add rule for generating yp_xdr.c and yp.h.
xdryp.c: gut everything except the special ypresp_all XDR function
needed to to handle yp_all() (this one can't be created on
the fly), and xdr_datum(), which isn't used internally by
libc, but which as documented as being there in yp_prot.h,
so what the hell. We now get everything else from yp_xdr.c.
yplib.c: change a few structure member names to match those found in
yp.h instead of those declared in yp_prot.h.
seems to work hre just fine though I can't check every file
that changed due to limmited h/w, however I've checked enught to be petty
happy withe hte code..
WARNING... struct lkm[mumble] has changed
so it might be an idea to recompile any lkm related programs
up. The effect of this was that msync with a size would generally sync
1 page less than it should. This problem was brought to my attention
by Darrel Herbst <dherbst@gradin.cis.upenn.edu> and Ron Minnich
<rminnich@sarnoff.com>.
metadata and VBLK type devices. The code is currently mostly disabled,
and a work-around has been added to disabled attempted clustered writes
for VBLK type device buffers. Clustered write of meta-data is currently
a work in progress.
Update rpcgen with the one from the TI-RPC 2.3 distribution.
Note that when built for FreeBSD, this version of rpcgen assumes
backwards compatibility mode by default. This means that it will produce
ONCRPC 4.0 compatible code unless otherwise instructed, instead of the
other way around.
One incompatibility has also been worked around: this rpcgen normally
always emits an '#include <stropts.h>' directive whether you select
backwards compatibility mode or not. We don't have STREAMS, so this
behavior has been changed: now it will only emit this line if run in TI-RPC
mode.
The 'generate output files in current directory instead of the
directory where the protocol definition file lives' hack from the
original rpcgen has been preserved.
Notable new features:
- Can be used to generate RPC servers that can be launched
from port monitors such as inetd(5).
- Can generate ANSI C code.
- Can generate sample client and server top-level programs and
makefiles in addition to the usual client and server stubs.
- Can generate inline XDR routines.
all buses.
Known problems:
-The PCI probe code has not been tested. Someone with a PCI Bt card will
have to validate it, but even if it is broken all cards the earlier version
of this driver found in ISA compatibility mode should still be found.
-Still missing the BT956 PCI ID, so it will be found as an ISA card until
someone suplies it.
-PCI interrupts go through an interrupt stub that returns an int until
we remove the edge-triggered PCI compatibiliity cruft.
-ISA interrupts go through an interrupt stub until they pass in (void *).
-The driver could support more mboxes and concurrent commands by allocating
structures separately and hanging them off the bt_data struct to get around
the 4K page limit. Someone with documentation should do this and also
enable tagged queuing.
can be found in ISA compatibility mode by the ISA driver, but since the
EISA and PCI probes are non-invasive, we prefer them to find the card first.
Since both EISA and PCI probes can rely on interrupts, enable them before
probing of any type is performed. All ISA probes are still "protected" by
splhigh().
allow one EISA/ISA/PCI/VL Buslogic controller to be probed. The driver
is almost fully dynamic. It just needs some kdc work and for the SCSI code
to stop passing unit numbers up in the scsi_xfer struct.
"getblk" hang. The B_WANTED flag was being cleared gratuitously,
also the optimization of gbincore for ignoring the B_INVAL flag was
incorrect. There is no place in the code where buffers are on the
hash list that are B_INVAL and not B_BUSY.
via mmap() up around the shared library area. Previously the directory
was allocated from space from it's own memory pool. Because of the way it
was being extended on processes with large malloced data segments (ie: inn)
once the page directory was extended for some reason, it was not possible
to lower the heap size any more to return pages to the OS.
(If my understanding is correct, page directory expansion occurs at 4MB,
12MB, 20MB, 28MB, etc.) I was seeing INN allocate a large amount of short
term memory, pushing it over the 28MB mark, and once it's transient demands
hit 28MB, it never freed it's pages and swap space again.)
I've been running this in my libc for about a month...
Also, seperate MALLOC_STATS from EXTRA_SANITY.. I found it useful to call
malloc_dump() from within INN from a ctlinnd command to see where the hell
all the memory was going.. :-) I've left MALLOC_STATS enabled, as it has
no run-time or data storage cost.
