soren 38a44e0d8f Consistently use pmap_steal_memory() to allocate USPACE. 2000-11-27 05:57:25 +00:00
chs c62d17a551 rationalize the use of b_flags for geteblk() buffers.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

wdk ff5d9dc3a7 Change default kernel format from ECOFF to ELF now we can boot ELF using
libsa based bootstraps.   This is now the prefered format.

ECOFF format kernel renamed to netbsd.ecoff - still required for network
booting.

abs 2824f4906d Ensure all INSTALL* kernels have two ptys, and a note explaining why:
pseudo-device  pty             2       # pseudo-terminals (Sysinst needs two)
(Some installers may not be using sysinst, in which case this just reduces
the number of ptys from 16 that are not used to 2 that are not used)
For i386 conf files, no change other than comments.

wdk 50e120c13f Parse boot string intelligently to extract the boot device options.

wdk 7495cd76b1 Since we don't have a lseek function in the PROM firmware standalone libs
we have to poke the data structures directly to force the offset we need.

The open() function returns with the address of the IO control block in
register t0 so we take a copy of it for our brute-force lseek function.

This should be reasonably portable since the firmware writers closely
follow UNIX semantics and the open stubs should recompile and use the
same registers.   May break on the rebadged clones -- buyer beware.

The alternative is to use dummy reads to go forwards and reopen followed
by dummy reads to go backwards.  It takes around 60 seconds to boot
using this method if we use a clean filesystem.

Tested with firmware versions 5.40 and 5.43

2000-09-24 15:59:26 +00:00
jdolecek 49c105ffdb add new macro BOOT_FLAG() (defined in <sys/boot_flag.h>) - this
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate

as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro

for hpcmips, use new bootverbose instead of it's own hpcmips_verbose

Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.

wdk 513cc0ca27 Linker script for building first stage bootstrap. Due to bugs/limitations
in the MIPS prom loader we have to be very careful how the sections are
ordered and the number of sections defined.   For this reason the standard
linker scripts cannot be used.

The exact rules don't appear to be documented and a little experimentation
is required.

wdk a3ec172607 Initial commit of a 2 stage bootloader for NetBSD/mipsco. Based on pmax
and alpha ports.

Uses PROM standalone I/O functions but due to the lack of a lseek function
it currently only works with version 5.40 of the firmware.  A more portable
solution is being worked on.

installboot utility requires several changes in order to correctly install
the bootstrap code - there is a "volume directory" which contains a list
of filenames, start sectors and length.  We need to add a "boot" entry of
the correct length starting at block 2.  The boot file has to be ecoff
which means we waste another 0.5k

Normally the Mips filesystem has a ~500k partition for this purpose but it
should be possible to squeeze it all into the first 7k "BSD Style" (1k is
required for 2 different copies of the partition table)

Only the bootxx_ffs first stage bootstrap has been tested via bootp() which
loads the second stage off disk and then boots the kernel.

wdk b38096892a Microtime calculation was seriously incorrect when HZ != 100
Give rest of clock interrupt code a revamp.  Because we are using an external
cycle counter we can now handle loosing several hundred interrupts without
the time slipping.

wdk 149a5fc5f2 Engage the clutch before changing gears.
If the machine uses a Z85230 ESCC device with deep buffers, we observe
output glitches when printing the zstty{0,1} probe lines when the device
is reset & reprogrammed during startup.

There is no easy 'hook' in the MI Z8530 driver, so we wait for output
buffer to drain before changing the baud rate generator prescaler value.

wdk 5656bdea79 Don't trust the realtime clock if the data is before 1988. This is
consistant with other ports.

Prevent uninitialized time from being written back to the RTC (1-Jan-1970)
if the machine is halted from the root device name prompt

wdk aaa3f11967 Fix an obscure bug with dump corrupting files during raw reads.
If the DMA chaning interrupt couldn't be serviced immediately (higher spl
level when kernel doing something else) a few microseconds later the NCR
controller will fill its FIFO and also interrupt the CPU.

The SCSI interrupt sees the terminal count has been reached, calls
asc_dma_intr to finish the job off.   The FIFO cannot be flushed because
the block count hasn't been setup for the last dma segment (DMA chaining
still wasn't serviced).

Since the NCR 53c94 FIFO is only 16 bytes in size, any short DMA in this
size combined with the machine 'doing something else' causes the problem
to occur.

Servicing the DMA chaining interrupt before the NCR SCSI interrupt solves
this problem.

Add tests to ensure the DMA FIFO has been flushed correctly at the end of
each DMA operation just to be on the safe side.

wdk caa807ac35 * Tidy up reading of Mips volume header information
All compatable values are copied from the MIPS volume header to the
  BSD disklabel structures.

* Add support for writing Mips volume header.

* Remove support for writing NetBSD label directly (this was broken)

These changes allow the kernel to read either a BSD disklabel created under
NetBSD/sparc or a MIPS volume header created under RISC/os.

There is a small amount of losage with the conversion between the 2
types of disk labels (mainly to do with file system types).
A table is used to map partition numbers and types between the two
types, and unless someone does something real fancy (or crazy) it should
work in both senario's

This change will allow the stand alone shell to directly load a NetBSD
kernel and mount a file system, avoiding the need for a seperate disk or
bootp server to bootstrapping NetBSD.

NetBSD/mipsco is now self sufficiant.  We are not far from having a
miniroot filesystem and removing the need to have another NetBSD
machine to create the base filesystems.

Minor Trap for young players:
   The root partition must be created with 'newfs -O' in order for the
   stand alone shell to boot the kernel

TODO:
   Add support for writing NetBSD disk labels back in - it will be useful
   for non boot disks.   I'm just not sure how to control the 2 behavours
