cgd 2f614ee518 update for new bus.h 1996-10-22 21:34:19 +00:00
cgd 8f5cf31b8a clean up the recent reimplementation, and kill several bogons in the new 
definitions.
 1996-10-22 21:23:49 +00:00
cgd 6d917387e4 there is no TC I/O space, so in the new bus.h world order there 
is no tc_bus_io.c.
 1996-10-22 21:15:45 +00:00
mhitch 39079306ce Add the missing ".set noreorder". 1996-10-22 20:46:09 +00:00
pk fd8ac8b221 If no specific kernel architecture is requested, define the CPU_* and 
NBPG et.al. as in the generic case. This would be the expected thing to do
when compiling LKMs and such.
 1996-10-22 19:11:19 +00:00
cgd 48dc9aaae4 update alpha bus.h for new bus space interfaces. chipsets haven't 
been updated yet, and the hacked DMA vto(busphys) macro is gone and
hasn't yet been replaced.
 1996-10-22 18:06:54 +00:00
veego cf6307b2e7 Fix GRFTOGGLE. 
The old version only toggles to the amiga signal and do not go back to
the CyberVision signal.
 1996-10-22 16:59:56 +00:00
perry 8ca5cce5c7 sync (mostly) with Alpha version. Among other things, this fixes the 
boot-time printf better.
 1996-10-22 16:38:34 +00:00
gwr b0e589ced7 Define the *poll functions. 1996-10-22 15:58:12 +00:00
perry ac4e0ab44e add a missing \n in the printf in rd_attach_hook. added an XXX 
comment to note that this printf still isn't quite right (possibly
because this is now a pseudodevice), and the autoconf printout when
mounting root on a ramdisk isn't right, either. This should both be
fixed.

thorpej b84a8f42d9 Implement eisa_mem_{alloc,free}(), a method for allocating/freeing 
EISA bus physical address space.

This i386 implementation allocates system physical address space
after the end of RAM.
 1996-10-21 23:12:56 +00:00
thorpej 16c4c5af26 New bus.h implementation/interface: 
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

increase the number of bpfilters to 16
 1996-10-21 11:13:39 +00:00
veego c8902b053c include update for config(8) 1996-10-21 11:11:23 +00:00

Copy the GENERIC config file and use that.

scottr 289b73be85 Fix a raft of printf format strings and some declaration problems for 
the case where we define DEBUG.  From Erik Bertelsen, closes PR 2871.
 1996-10-21 05:42:23 +00:00
briggs 084b3f6a4c Fix two bugs noticed by Taras Ivanenko <ivanenko@ctpa03.mit.edu> 
via.c: don't allow spl to remain at splhigh on error.
mainbus.c: Make sure that variable is initialized.
 1996-10-21 01:59:31 +00:00
perry 7117cf93ec Add #include <sys/systm.h>, so that cc -W* doesn't bitch and error out 
when printf() gets used in this file.
 1996-10-21 01:49:22 +00:00
scottr a6865e3d2b Don't try to reference nfsbootdevname if we have no ether devices. 
Fixes PR 2860, from Paul Goyette <paul@pgoyette.bdt.com>.

thorpej 43ba106ec2 Remove declaration for now-gone function. 1996-10-20 23:47:40 +00:00
thorpej af8d8d2a56 Arrange this file into sections (configure(), root device goo, console goo, 
old-config goo).  Place old-config goo at the end so that it's easy to
#ifdef our or delete (muahahah!).

Garbage collect a couple of unused functions.
 1996-10-20 23:46:06 +00:00
thorpej bbdd41a2a7 Back out last change, and add a comment about what should happen. 
(*grumble* will teach me to do a `make clean' next time.)
 1996-10-20 23:23:28 +00:00
hpeyerl 7aa41bf1a7 #ifdef out a couple of variables dependant on USER_LDT. 1996-10-20 22:39:03 +00:00
pk 52acac0518 Regroup the definitions of NBPG, PGOFSET and PGSHIFT into the section that 
enumerates the possible SUN? combinations.
 1996-10-20 20:26:52 +00:00
pk 62c32ff2dc Drop a duplicate `#include ppp.h'; noted by Chris Demetriou. 1996-10-20 19:32:42 +00:00
pk 4dd0b24bf9 Make sure to refer to `sc_ovtype' only when SUN4 is defined, as noted 
by `r.evans@ic.ac.uk'.
Also, explicitly testwhether we're dealing with a pfour.
 1996-10-20 19:18:00 +00:00
pk b246894d9b Document `-a karch' option. 
Fix a formatting nit.
 1996-10-20 16:17:04 +00:00
pk 5ced353a7a Add `-a <arch>' switch to force the target architecture. Retain `-h' for 
compatibility.
 1996-10-20 16:00:14 +00:00
thorpej 7133ecf2ca Don't need to mark 0-NBPG as VM_PROT_NONE in kernel_map anymore; the 
first entry is now properly setup in kmem_init().
 1996-10-19 21:11:32 +00:00
thorpej 7958973110 Set VM_MIN_KERNEL_ADDRESS to NBPG. This is a better way of getting 
the kernel_map to treat page 0 properly.
 1996-10-19 21:07:42 +00:00
is e10e9e8455 Clean up the attach messages a bit. 1996-10-19 16:54:14 +00:00
thorpej cf9b36ab1d Set up a kernel_map entry for the text segment with protection of 
VM_PROT_READ|VM_PROT_EXECUTE.  The previous default (VM_PROT_ALL)
would cause the following scenario:
	- someone attempts to write kernel text (my test was writing
	  to an offset of /dev/kmem which was known to be in the text
	  segment, while in single-user mode).
	- enter trap() with MMU fault (because of RO pte).
	- trap() calls vm_fault(), which looks up vm_map_entry for
	  fauling address.
	- vm_fault interprets write fault and VM_PROT_WRITE (in VM_PROT_ALL)
	  as COW; new page allocated, data copied to new page, new page
	  mapped in at trunc_page(<faulting va>).
	- wow, look at the fireworks!
Fixes two potential symptoms:
	- kernacc() returns TRUE when checking for permission to write
	  an offset in kernel text, which is bogus, since the text has
	  been mapped RO by pmap_bootstrap().
	- Handling of a stray pointer that attempted to scribble into
	  kernel text would not be executed properly.

cgd a6d9feb7a5 clean up chrtoblktbl, adding comments naming the devices which actually do 
have entries in both device switch tables.  Add 'st' entry to chrtoblktbl.
 1996-10-18 21:26:57 +00:00
cgd 44365140cf Severely clean up netisr handling. Clean up includes for netisr handlers. 
Fix PPP netisr handling, add NATM netisr handling.
 1996-10-18 20:35:23 +00:00
fvdl d1400746a5 Fix some printf formatting strings within DEBUG and DIAGNOSTIC defines. 
From Mike Long, PR 2859
 1996-10-18 09:03:42 +00:00
thorpej 6126eea479 Tell the `upper half' of the VM system that page 0 isn't mapped. If we 
don't do this, kernacc() will bogusly return TRUE for page 0, causing a
NULL pointer dereference in uiomove() when reading /dev/kmem.

Thanks to Scott Reynolds for noticing the problem.
 1996-10-18 08:57:14 +00:00
thorpej 150c33e60b Use ${INSTALL}. 1996-10-18 05:55:26 +00:00

by Andrew Gillham.

fvdl f9a53c581f Cast ioport_ex_storage to caddr_t, needed becauseit is now long[] 
and creates warnings.

cgd 8f799be896 add a WEAK_ALIAS macro if building on an ELF-capable system, which creates 
a weak alias for a symbol.
 1996-10-17 18:33:53 +00:00
is 7e1b190155 Change Blizzard IV/1260/2060 to the name used by the driver. 
While we're here, clean up a few other entries.
 1996-10-17 15:49:39 +00:00
is 8f5996c976 Add driver bznsc (for BliZzard, New version: -IV, -1260, -2060). 
Still untested on -1260/-1230, and hangs when enforcing SFAS_NO_DMA on 2060;
but works with DMA on the latter.

Still untested in a NetBSD-12A environment. (Sorry, don't have the hardware
myself.)

Thanks to Laurent Baroukh for being the guinea pig, and to Jerome Lovy
for forwarding the hardware information Phase V gave him, and to Phase
V for providing it.

ws 2c65d27e6b Forgot to "cvs add" this in the last: 
Rename recently checked in KGDB to IPKDB to resolve conflicts with older KGDB
 1996-10-17 12:09:05 +00:00
thorpej 78bce16293 Couple of changes: 
- Rename EX_NOBLOB to EX_NOCOALESCE; it's much more descriptive of
  what's going on.
- Ensure that fixed extent storage is longword aligned.
 1996-10-17 08:31:28 +00:00
scottr 6bb6fab4ce Changes from the hp300 trap.c: 
- Fix up usage of MBD_ISPID().  (from Jason Thorpe)
- Be careful not to deref bad pointers in the MMU fault handler.  (ditto)
- Ensure trap() never deals with a NULL proc, and if our proc has
  no pcb, punt.  (Suggested by Gordon Ross)
