and shares some bits with ISA AT1700 driver. Gee, this one was really
easy :)
This card turned out to be quite good performer - I get about 360KB/s
on 386DX PS/2 machine, which is best of all supported cards so far.
and use appropriately
- create more helper macros:
. cdev__xyz_init(c,n), such as cdev__ocri_init() for
/* open, close, read, ioctl */, etc.
. cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
method `R' and the comments now read /* xxx (read) yyy */ instead
. cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
as well
- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
always DTRT WRT returning a valid result. (a few devices previously
incorrectly returned ENODEV)
- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
== 0, because it doesn't matter if dev_type_stop isn't implemented in that
case, and it allows the use of the cdev__xyz_init macros. certain ports
(sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
drivers, whereas everything else uses enodev
- ensure that the comments are accurate WRT the behaviour of a given entry
they keep giving error 0x30b. Unfortunately this keeps happening every second
making the console unusable. Keep track of the last error that occurred and
if the last 10 times apm was called the same error was returned, give up and
exit the apm thread.
WD8003W/A, card provided by David Brownlee (thanks!). The SMC Elite stuff not
tested since I don't have any; hopefully it's correct, should match
information in ADF files.
The MCA-specific init quirk taken from Linux smc-mca.c driver.
I don't quite grok why it works, but it does *cross fingers*.
The WD8003W/A seems to be quite a good choice. I get like 340KB/s on my
machine, where 3c523 does only like 310KB/s. The numbers would be probably
even better with faster CPU than 386DX :)
provided to me by David Brownlee (thanks!).
Performance of this card is quite poor on my PS/2 with 386DX, like 100KB/s
at best, but as low as 5KB/s when transferring bigger files due to
packet overruns. It would be good to revisit this later, probably by
teaching the ic code to use RX Early.
of uvm_fault() to the onfault routine via %eax. users of pcb_onfault now
return this value to their callers rather than always returning EFAULT.
this allows i/o errors in VOP_GETPAGES() to be returned back to read(), etc.
Remove duplicate prototype for i386_{set,get}_ldt() from sys_machdep.c.
Change i386_iopl() and i386_{set,get}_{ldt,ioperm}() to take a second
argument of "void *" instead of "char *", for consistency with other syscalls.
revision 1.76. It avoids problems where an I/O interrupt for physio,
using a bounce buffer, would find the destination address mapped
read-only because the syncer process hit.
Suggested by Chuck Cranor.
when the display is closed, the machine suspends (as expected).
when the display is opened again, it resumes and suspends again
(must manually wake).
problem happens because driver fills the event queue with duplicate
events without allowing apmd to drain it by running. fix it by
improving detection of duplicate events.
also cleanup and add some extra APMDEBUG code.
all of the read-only data. Move _etext after all the read-only
data in the LARGEPAGES script, as well.
This will cause const data to actually be const on i386 kernels now
(it was, by sheer luck, on LARGEPAGES kernels simply because of the
section rounding that the LARGEPAGES script performed).
other __HAVE_* defines are). Conditionalize definition of old
disklabel struct and ODIOC* definitions on it, allowing other ports
to bump the number of partitions in the label if they want to
(see comment in sys/disklabel.h).
This is the kernel part (userland to follow soon) of the latest (and
very probably last) release (version 0.96) of ISDN4BSD. ISDN4BSD has a
homepage at http://www.freebsd-support.de/i4b/.
It gives the user various ways to use the isdn connection: raw data (via
the i4brbch "raw b-channel" device), ppp (via the isp "isdn PPP" device),
voice/answering machine (the i4btel "telephone" device) and ip over isdn
(the ipr device, "IP over raw ISDN").
Supported are a bunch of common and older cards, more to be added soon
after some cleanup. Currently only the european E-DSS1 variant of the
ISDN D channel protocol is supported.
tlbflush() when that's what we mean (currently everywhere, except
in the one place in MI code where it is called).
The whole pmap_update() thing needs to be reexamined, but this helps
to clarify things a little with the currently-defined semantics of
that function.
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.
Tested on alpha and i386; welcome to 1.5Q
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare). really sorry
for the mess.
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx
This addresses kern/10981 by Matthew Orgass.
Just like any ISA device, if you don't have the device at the configured IRQ,
you could lose if something else decides it wants that IRQ. wss is not
a special case.
shared FreeBSD binaries coredump.
This solves port-i386/11708 by Atsushi Onoe.
XXX it may be worth it to split FreeBSD syscall code off syscall.c similar way
XXX as other emulations
GENERIC is the kernel used on new installs and too many things overlap the
resources (irq mostly) the default isa version may be using which causes
panics on reboot.
returns for floppy controllers i/o ports. i.e.
1. 1 range of length 4 (which conveniently "forgets" the ctl i/o port),
2. 2 ranges: 1 of length 4 and the ctl i/o port.
3. 1 range of length 6 which goes to the end of the ctl i/o.
Make this line up with the MI fdc code by mapping in a range of 4 on the
base i/o and then either direct or submapping the ctl i/o. In the one case
where the BIOS lies and says it's not there just map it in anyways. (but note
the fact to the end user).
This is very adhoc work for IETF meeting.
- Since it seems that 'an' and 'wi' have similar hardware, low level
functions should be shared.
- There are PCI/ISA cards of Aironet but not supported yet.
- The wiconfig interface is changed so that wiconfig cannot be used.
- 'ancontrol' of FreeBSD is not ported.
- Only infrastructure mode is tested.
- WEP is not supported.
Though I only have an Aironet card, Cisco card should be expected to work.
* __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by
e_syscall_intern, which is called at key places in the kernel. This can be
used to set a MD syscall handler pointer. This obsoletes and replaces the
*_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in
struct emul are omitted.
