ff89e6613e Removed some macros that are now in cpufunc.h

8db02de884 Added MCOUNT_ENTER and MCOUNT_EXIT macros to profile.h
Removed inb function since it's more correctly in pio.h

Copied write_eflags and read_eflags over from npx.c

(Some changes to the macros suggested by Bruce were not made at this
time since his suggestions probably apply to all the macros and
these inlined/macro definitions need a lot of cleaning up at some
point in the future.)

3443a7b245 Brought over from 1.1.5:
Fix from Bruce Evans. There were missing sets of parantheses:

1. The checks for the standard data selectors were botched, so %ss == 0
   and probably %cs == 0 were allowed.  A fix is enclosed.  The checks
   for the standard selectors could be omitted without losing anything
   since the standard selectors pass the valid_ldt_sel() tests.

4f683116b4 Added support for many more videomodes, including graphic modes up til
320x200 256col VGA. This is nessesary for the iBCS stuff to work right.
(And we get the benefit of more video modes). Uses the videocard BIOS
to optain mode tables.
Added a "green" saver, switches off the syncs for "green" monitors.

82a2eb57c0 Beginnings of support for loadable protocol domains. In particular,
don't hard-code netisr values in icu.s, but rather, use an array of

protocol families.  (This will eventually be done differently.)

f86233fe54 Added a bit of missing functionality to make this work correctly on a
wider variety of systems.  Include the deivers from pci_intel.c in
pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev().  Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
own drivers, and don't call not_supported() for them.  (This shuts up
complaints about my Matrox card.)  Include the beginnings of what could
eventually become dynamically-loadable PCI devices.  Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
Make autoconfiguration text conform more to the style of other supported
buses.

66ce0eae53 Added DSI_SOFT_MODEM 1994-09-13 03:34:08 +00:00
Poul-Henning Kamp
5b7ffe398f Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support.  This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.

To get this functionality, you must define DSI_SOFT_MODEM.

The program to actually employ the ioctl is not included, but the entire
source looks like this:

        #include <sys/ioctl.h>
        #include <stdio.h>

        main()
        {
                unsigned char buffer[100000];
                int i;

                read(0,buffer,100000);
                if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
                    perror("ioctl");
                return i;
        }

And you use it like this:
	smload < data144b.dsi > /dev/ttyid3

You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

30902edcfb ProAudioSpectrum 16 {Zilog|Ncr} 5380 based SCSI-driver.
This puppy is in good shape now.

It is a fully blown SCSI-driver, but it isn't a high performance one.  It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes.  It will run disks and tapes if asked to, but it isn't a
very good idea to do so.  Transfer-rates max out at 600-700 kbyte/sec.

There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls.  This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok.  I have circumvented this by disabling the
pseudo-DMA in those cases.

It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.

You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.

I will fix any bugs I can get a handle on.

6bf5b24768 Don't include options MULTICAST or MROUTING in generic kernels. MULTICAST
has no effect now, and MROUTING should never be defined by default.
(Eventually the code should be dynamically loadable.)

Also, allow for Pentium CPUs in GENERICBT kernels.

Add an `install' rule to Makefile.i386, which looks like this:
	mv /kernel /kernel.old
	install -c -m 555 -o root -g root -fschg kernel /
I'd like comments on whether or not you think it's a good idea to have
the kernel be immutable by default; I'm happy either way.

ab9678ac9d Get all the definitions from DEFS.h and not directly from asmacros.h
if KERNEL is not defined.  lib/msun/i387/*.S include asmacros.h to
get the definitions of ENTRY(), etc.  This is bogus since asmacros.h
is only supposed to give definitions suitable for the kernel.  The
current definitions for the kernel almost worked but are missing
the ".type" declarations.  This caused the linker to print warnings
about doubtful relocations for almost anything linked to libm[sun].
