81d960fa6d Implementation of the linux_getcwd syscall. 1999-08-14 18:20:44 +00:00

e000c53684 Extend the number of syscalls to include those present in Linux 2.2.10. These
are syscalls 183 to 190. Also implement syscall 183: linux_getcwd. This is
needed to support a RH 6.0 environment.

06ebbe77ed Implementation of linux_rt_sigaction and linux_rt_sigprocmask syscalls. Both
functions use the new sigset_t and sigaction_t which allows support for more
than 32 signals. Only the lower 32 signals are supported for now.

linux_rt_sigaction, linux_sigaction and linux_signal use linux_do_sigaction
to do the actual work. That way unnecessary redundancy is avoided. The same
has been done for linux_rt_sigprocmask and linux_sigprocmask. They call
linux_do_sigprocmask to do the actual work.

3bde119b1e Fix LINUX_TIOC{S|G}SERIAL implementation. Both do not copy data in or out
of kernel space. Remove the ioctl supporting functions, and move the actual
code to the switch-statement. Now everybody can clearly see that the
implementation is really poor.

Also fix a typo in LINUX_TIOCGETD. The underlying function was given command
TIOCSETD instead op TIOCGETD...

49ff4debd3 Spring cleaning around strategy and disklabels/slices:
Introduce BUF_STRATEGY(struct buf *, int flag) macro, and use it throughout.
please see comment in sys/conf.h about the flag argument.

Remove strategy argument from all the diskslice/label/bad144
implementations, it should be found from the dev_t.

Remove bogus and unused strategy1 routines.

Remove open/close arguments from dssize().  Pick them up from dev_t.

Remove unused and unfinished setgeom support from diskslice/label/bad144 code.

432d528c8d Fix a couple of termio/termios conversion bugs/typos/dupos/brainos and other
changes. This is part 1 of the complete termios ioctl fixes.

o  change type of c_{i|o|c|l}flag in struct termios from unsigned long to
   unsigned int. The type now matches the Linux definitions.
o  replaced constants by the corresponding defines in sptab[] for clarity.
   Since there's no define for 135 baud, its mapping has been dropped.

function bsd_to_linux_termios:
o  Fix typo IXON -> IXANY.
o  Remove bogus assignment to c_cc[LINUX_VSWTC].

function linux_to_bsd_termios:
o  Fix dupo LINUX_IXON -> LINUX_IXANY.
o  Add LINUX_CREAD mapping.
o  Fix typo IEXTEN -> LINUX_IEXTEN.

function linux_to_bsd_termio:
o  Small optimization: Don't preset the complete c_cc array when we next
   assign to the first LINUX_NCC entries.

accc665bbe Hopefully fix the previous commit, it caused *all* bridges to be detected
as PCI->HOST bridges on my (440BX) box.

My change is to remove the test at the beginning entirely, letting the
switch on the device ID happen first.  If the device ID is unknown, then
(in the default case) check for the generic PCIS_BRIDGE_HOST tag.  This
should allow wierd cases (eg: wpaul's IMS VL bridge) to work by using the
id override.  This strategy is more in line with the other PCI match
methods we use elsewhere,

I only have a limited testbed, but having my USB etc devices detected as
PCI->HOST bridges doesn't look good.

d9d628b000 Fix nexus_pcib_is_host_bridge() so that it detects my 486's PCI bus
correctly. It has the following code:

        if (class != PCIC_BRIDGE || subclass != PCIS_BRIDGE_HOST)
                return NULL;

My 486 has an Integrated Micro Solutions PCI bridge which identifies
itself as subclass PCIS_BRIDGE_OTHER, not PCIS_BRIDGE_HOST. Consequently,
it gets ignored. In my opinion, the correct test should be:

        if ((class != PCIC_BRIDGE) && (subclass != PCIS_BRIDGE_HOST))
                return NULL;

That way the test still succeeds because the chip's class is PCIC_BRIDGE.
Clearly it's not reasonable to expect all host to PCI bridges to always
have a subclass of PCIS_BRIDGE_HOST since I've got one that doesn't.
This way the sanity test should remain relatively sane while still allowing
some oddball yet correct hardware to work. If somebody has a better way
to do it, go ahead and tweak the test, but be aware that
class == PCIC_BRIDGE and subclass == PCIS_BRIDGE_OTHER is a valid case.

While I was here, I also added an explicit ID string for the IMS chipset.
I also dealt with a minor style nit: it's bad karma not to have a default
case for your switch statements, but the one in this routine doesn't have
one. The default string of "Host to PCI bridge" is now assigned in a
default case of the switch statement instead of initializing "s" with the
string before the switch and then not having any default case.

942fd180df We don't end up checking for a return value of EFAULT from the copyinstr()
in the pathname translation procedure. This proves fatal, and can be
easily fixed. This or a similar change needs to be committed to svr4_util.h
and ibcs2_util.h. I will update ibcs2_util.h, if noone else thinks of a
better way to do this, in the same manner. I will leave svr4 to the
respective maintainer.

This closes the problem of the only crash I've been able to produce as
a user recently, except for (currently not-in-the-source tree) fd
table sharing fixes. Thanks goes to pho for his stress-testers.

0d6ab4a16a Move the specification of EDGE/LEVEL triggered interrupts to
eisa_add_intr() which now takes an additional arguement (one of
EISA_TRIGGER_LEVEL or EISA_TRIGGER_EDGE).

The flag RR_SHAREABLE has no effect when passed to
bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as
the eisa_alloc_resource() call (bus_alloc_resource method) now deals
with this flag directly, depending on the device ivars.

This change does nothing more than move all the 'shared = inb(foo + iobsse)'
nonesense to the device probe methods rather than the device attach.

Also, print out 'edge' or 'level' in the IRQ announcement message.
