ragge 60af617a5d Totally new approach for MSCP devices; they are now handled more like SCSI.
All Unibus dependencies are removed.
Can support different controllers on different buses.
Allows cloning of devices.
TODO:
	Write support for MSCP tapes.

ragge 97756165b8 Remove code that took care of old config devices. Don't support
old config anymore, all devices should use new config by now.
Add structures to handle DMA devices using new config.
Fixed bug that caused unwanted ubareset's on 11/780.

abrown 410fea854a Implement asm macros to allow 64-bit load/store to alternate address space.
Use new ldda() and stda() to make MultiCache initialization work on
SuperSparc-II machines (these machines require 64-bit access, even
to a 32-bit register).

fvdl b27bafebd5 We're only handling uio with iovcnt == 1, so don't ever attempt to increment
uio_iov, this will get us into nasty trouble. (Thanks to Matthias Drochner for
tracking this down).

is 6e4842626b There are Blizzard boards without SCSI options - we need to probe for the
existence of the SCSI hardware in the boards adress region.
Thanks to Oster Nerhus for the detailed bug report and to Ralph Schmidt for
the recommended probing method.

chuck 921ed68fff new: add a raw_threshold for raw mode. this basically tells the driver
to ignore inbound data sizes less than the threshold.  otherwise,
        when connected to a video aal0 input the driver gives us a massive
        stream of 56 byte mbufs each with one aal0 cell in it and the
        system just can't keep up with it, especially if the socket buffer
        size is large [it hangs until you turn off the video source].

fixes: when turning off a vc, try and check the freshest copy of the mode
        when seeing if we need to enter the "drain" state.   also, don't
        panic if we get unexpected rx interrupt on a VCI (instead make sure
        the VC is off, print a warning, and move on!).

chuck 685684df93 change:

        level.
fix:
 - forgot to init "vci" during ENOTHER_DRAIN case of RX DMA interrupt
        [could cause a vm_fault on native mode connection close depending
        on needing to drain out the VC and also the random value of vci]

thorpej fc699e8440 Major revamp of the boot code.
- Good bye SYS_PBOOT and SYS_NBOOT, hello SYS_UBOOT (unified boot)
	  Currently supports booting from SCSI and HP-IB disk and network
	  from a single boot block.  Infrastructure for booting from
	  HP-IB tape is there, but it doesn't quite work yet.

	- Add a slightly modified version of Gordon Ross's "rawfs",
	  which provides a filesystem-like interface to tape devices.
	  Still needs debugging (see above).

	- Rename sys_inst.c to inst.c, so that the LIF directory entry
	  turns out right (used to look like SYS_SYS_I if loaded from
	  tape).

	- Add a "netio_ask" hint to netio.c, so that a special instnetio.o
	  doesn't have to be compiled for SYS_INST.  Defaults to using
	  bootparams, but if set, will prompt user for information
	  usually obtained from bootparams.

	- General cleanup.
1996-06-26 17:44:21 +00:00
is a63c9b84e2 - Add code to loadbsd.c to allow booting on DraCos. This could be done
in a more elegant way, but it works as is, and we need it now.
- Add a README and Makefile for the above. Note that this directory should
  NOT be added to ../Makefile's SUBDIRS.

jonathan d41e338edc * Put in fix to in bytestuffing/RLL code from Stuart Cheshire, that
somehow got lost between NetBSD and Linux.    Output side mbuf-walking
  code now correctly bytestuffs mbuf chains, as well as single mbufs
  and clusters.

* Update radio error-parsing code to Stuart's latest stable code.
  We now parse error messages the older code didn't.

* Note where radio-crash watchdogs should be added (the linux code
  is there, #ifdef'ed out). This still just  doesn't work.
  The radio reset doesn't always work even when slattatch is first started,
  but I have a radio with old firmware, which may be a contributing factor.

* Correct the checks for the tty output queue being overfull;  estimate
  the stuffed pkt size as  (original * 65/64) + STRIP_HDRLEN + 2,
  instead of SLIP's (2*SLMTU).  Re-enable the disabled  check now the
  size estimate isn't excessively large.

* Fix BPF tapping of strip interfaces,  STRIP packets are wrapped
  in a SLIP bpf  header.   This implies no BPF support for arp or atalk,
  even though Linux boxes are sending arp requests and  gratuitous arps.
  There may be no good  fix short  of adding explicit  STRIP encapsulation
  support to bpf/tcpdump.

* Still need a solid walkthrough, and  rewrite to eliminate redundant
  receive-side mbuf copying.

pk 1a04146533 A couple of emulation enhancements from der mouse's PR#2411:
- ability to be either a BROADCAST or POINTTOPOINT interface.
	- a humble beginning of link-layer addressing (differs from PR
	  by using a `struct sockaddr' instead of single byte).
1996-06-25 22:15:13 +00:00
thorpej 698844254e A few simple changes:
- Use an extent map to manage the ISA memory "hole", much like
	  how i/o port space is manged with an extent map.  Do the actual
	  accounting in bus_mem_{,un}map().

	- When creating the ioport and iomem extent maps, pass the
	  EX_NOBLOB flag, which tells the extent map code to disallow
	  fragmenting of regions.  This will make it easier to catch
	  simple i/o and memory mapping bugs (like the if_ed.c bug I just
	  fixed) in the future.

	- In bus_mem_map(), a chunk of code was indented using spaces.
	  Make the indentation use tabs.

	- In bus_io_unmap(), fix the format passed to printf().

thorpej 794614df64 In the 3c503 probe, map the correct number of ports. (Unmap already
unmapped the correct number of ports, thus causing the ISA io port
extent map to get corrupted.)

jonathan 8445253ad3 Fix 4.4bsd/pmax memory-sizing bug:
physical memory is sized by a loop that writes data to the first
word in a page, (writes something else to settle the bus) and then reads
back the word it wrote. If the read succeeds, the amount of physical
memory is increased by one page.

This fails on a 5000/1xx with a memory subsystem filled with 8 low-density
(4Mbyte) SIMMs. The memory-decoding hardware  aliases the 32Mbytes of
physical memory  at physical addresses 0, and at 32M (and presumably
at 64 and 96Mbytes.)  The contiguous aliasing causes the memory-sizing
loop to continue  at 32 MBytes, testing the memory that's really
at address 0,  overwriting and crashing the kernel.

Fixed (for 1.2) by reading the SIMM-decoder stride size from the
motherboard, and reducing the loop bound to 32Mbytes on a 5000/1xx
with low-density SIMMs.  (Other models have a non-power-of-2 maximum
memory and so are not subject to _contigous_ aliasing of physical memory).

pk 6e8ba625ef Ignore the mountpoint's `v_usecount' in nfs_unmount() if MNT_FORCE is on.
This takes care of two related problems:
	- `umount -f' wouldn't work if someone's working directory is
	  the filesystem root.
	- vfs_unmountall() would complain about a busy `/' on a
	  diskless setup.
1996-06-24 10:26:40 +00:00
jonathan 7620af6671 Fix 4.4bsd/pmax bug in memory-sizing loop:
The physical memory-sizer claims to preserve memory contents
(specifically the contents of msgbuf).  The loop writes different
values into two adjacent locations and reads the contents of the
first, to ensure that whatever is read back from the first location is
from memory and isn't just the first write persisting on the bus.

The loop preserved the value of the first location, but not the second,
resulting in the second test value ('ZZZZ') over-writing a word in msgbuf.

thorpej 9b69016c08 Now that we have i/o port accounting, change the mainbus attach
order back to the (correct) pci -> eisa -> isa ordering.
1996-06-23 20:11:27 +00:00
thorpej 8c2f15c6fc New implementation of bus_io_{,un}map() for the i386. Details:
- A fixed extent map (statically allocated descriptor storage) is
	  created in init386(), just before the call to consinit().  The
	  fixed descriptor storage has enough room for 8 region entires,
	  which is plenty for early initialization, but doesn't chew up
	  that much memory.

	  This extent map (ioport_ex) manages the i386 i/o port
	  space (0x0 - 0xffff).

	- Just before the call to configure() in cpu_startup(), a
	  flag is set which notifies the bus_io functions that it is
	  safe to use malloc() to allocate descriptor storage, in the
	  event that more than 8 regions are needed.

	- bus_io_map() attempts to allocate the specified region from
	  ioport_ex.  If the allocation succeeds, the io handle is
	  filled in.  If the allocation fails, it is implied that
	  something else is already using that io space, and an
	  error condition is returned.

	- bus_io_unmap() frees a region previously allocated from
	  ioport_ex in bus_io_map().  If the free fails, a warning
	  is printed on the conole.

These changes implement "port accounting".  This is required for
proper autoconfiguration on the i386 port, and makes dealing with,
among other things, PCMCIA io mappings _much_ easier.
