thorpej 43b4486bb3 Balance calls to disk_busy() and disk_unbusy() properly to avoid
dk_busy < 0 panics.  Count seeks.
1996-01-12 00:19:29 +00:00
thorpej 5b39541e48 New generic disk framework. Highlights:
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

mycroft 3afeb8d6b0 Make sure interrupts are disabled before jumping to a resume point, to prevent
races.

interrupts to avoid races.

perry 74e1e47aeb fixed my own pr 1758 -- the floppy drive motor was not being turned off
at halt time, especially if a floppy was mounted. Added a shutdown hook
to turn off the motor. Per a request by mycroft, the cookie from the hook
is saved in a new member I added to the fd_softc structure.

mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

fvdl 051bb183e3 Same as in 1.1 branch. 1995-11-09 08:40:51 +00:00
mycroft 72805df917 Various changes from John Kohl and me:
Map kernel stacks only at unique addresses.
Use one TSS per process.
Add sysarch calls for modifying IOPL and the I/O permission bitmap.
Add a compacting GDT entry allocator, for TSS and LDT selectors.
Enable modifying %fs and %gs with PT_SETREGS.
Sanitize various bits of code.
1995-10-11 04:19:29 +00:00
mycroft 25f53a986f Add USERMODE() and KERNELMODE() macros, and use them. 1995-10-10 04:45:03 +00:00
mycroft 8096b83664 Eliminate soft segment descriptors; instead use a functional interface for
creating segment descriptors.  Add the duplicate system call gate used by
BSD/OS 2.0 executables.  Prototype setsegment() and setgate(), and fix a bogon
caught by this.

jtc 9ba33c87cc Update makefile to handle the fact that keycap.5 was moved out of man5
into this directory.
1995-10-08 21:59:43 +00:00
jtc df99cef0ac Patch from Frank van der Linden to allow kernels with pcvt but without
XCONSOLE to compile.  I've been told that this patch has been sent to
Helmuth.

jtc 95f29581c3 Remove files that have been removed from or renamed in the current pcvt sources 1995-10-07 23:25:09 +00:00
jtc be0a951c76 Update our Makefile.inc.
Remove various OS-specific Makefile.inc templates.
1995-10-07 21:51:42 +00:00
jtc d9789d4225 Overlay our pcvt with pcvt 3.32 sources. All of our fixes have been
incorporated into the master sources, so it is unnecessary to resolve
all the conflicts that would occur if we let CVS "merge" the versions.

jtc 864f186a4e Use MAN instead of MAN8 (although it doesn't matter here because vgaio
is neither built nor installed).

fvdl 1b8c8d3906 Fix broken VT_WAITACTIVE ioctl (from pcvt 3.30, needed for Linux
svgalib binaries).

mycroft b8b9c4c9ff Make sure vt_coldinit() is always called before vt_coldmalloc().
Remove pcvt_kbd_raw.
1995-09-03 01:20:33 +00:00
fvdl 9fc36ab1a4 * Don't scroll by setting the CRT start address when in graphics mode, and
make sure to use the right buffer (fixed in the same way as pcvt 3.30)
* Maintain keyboard state locally per VT. This makes sense, enables switches
  between VTs with different kbd states, and aids Linux VT emulation.
1995-08-30 00:29:09 +00:00
fvdl a084a7d3dd Remove bogus check in ioctl(fd, VT_RELDISP, VT_FALSE). Needed for
Linux VT emul stuff. This fix was already applied in pcvt 3.30

mycroft a326c49adf Stop using cr0 to flag that the FPU has not been used. 1995-08-06 06:05:28 +00:00
mycroft ce7cc0c18a Move the `used fpu' flag into mdproc, so it can be referenced when a process
is swapped out.  Implement process_{read,write}_fpregs.
1995-08-06 05:32:59 +00:00
mycroft 7263209ce6 Make each disk and tape driver define its own read and write functions.
Deprecate rawread() and rawwrite() completely.  Remove d_strategy from cdevsw to
force the abstraction barrier.
