thorpej 716af300ee In query_bus(), use the parent pciconf_bus_t's PCI chipset tag, 
not the new bus's (which is potentially uninitialized when some
calls are made).

thorpej 671a1b111f Print the fault PC for non-USR Prefetch Aborts. 2001-11-09 19:04:23 +00:00
scw f1defc3543 To avoid backwards seeks on sequential devices (eq. QIC tapes), read all 
the program headers in one operation into an internal buffer.

scw 439d3ea3cb G/C some debug printfs inadvertently left in the last commit. 2001-11-09 18:27:59 +00:00
scw 2f42a5932e Implement just enough of an lseek() to keep loadfile_elf32() happy. 
While I'm here, bump RAWFS_BSIZE up to 8192 since the installation
instructions use "bs=8k oconv=sync". My Archive Viper now streams
nicely while booting.

scw dca93f1b48 The success/failure status for some Bug syscalls is indicated by the Z 
flag in the status register, not by a value on the stack.

How this ever worked for so long is beyond me...

thorpej 82c11eec1c Clear the Master Abort after reading config space for a non-existent 
PCI device.  Disable debugging messages, as PCI config space works now.
 2001-11-09 18:04:10 +00:00
thorpej 42a10f6cd4 Implement a badaddr_read() routine which performs a load of the 
specified size for the caller, and returns true or false indicating
whether or not a Data Abort occurred (i.e. the address was "bad").
 2001-11-09 17:58:00 +00:00
thorpej d16c00cfb2 Disable the ATU interrupt sources (i.e. interrupts that occur when 
we get Master or Target aborts).

the driver aborts.
Don't block RHSC interrupts.

augustss 3dd8433864 Add a debug message. 2001-11-09 14:59:11 +00:00
lukem bae654cfa1 When used without -F, search for `special' in fstab and use the raw version 
of the fs_spec. In any case, use opendisk(3) to open the device.

When used with -F just open `special' as-is.
 2001-11-09 12:01:13 +00:00
lukem fbab1e72fb move guts of non-F special parsing into separate openpartition() func 2001-11-09 11:48:39 +00:00
wiz 1c65d6114b Remove a trailing space. 2001-11-09 09:30:59 +00:00
lukem e48d7547e2 Change -F from "special must be a regular file" to "special can be any type, 
and don't attempt to do any file name translation (e.g, search in fstab)".

In the non -F case, search for special in fstab. If found, convert fs_spec
to a raw device name. In any case, use opendisk(3) to open the device.

thorpej 2436e0546d This is not a Sun3-specific program. 2001-11-09 07:43:16 +00:00
thorpej 13aa19d0fc Eval boards usually don't have boot loaders. If we're lucky, we 
have firmware that understands ELF.  We're usually stuck with S-Records.
To make life easier, attempt to stuff kernel symbols into the image
with dbsym(8).

If the kernel doesn't have SYMTAB_SPACE, or if the SYMTAB_SPACE is too
small, the kernel build continues as normal; this is just a convenience
measure.

thorpej 028f694d86 Make an error message more informative. 2001-11-09 07:36:03 +00:00
thorpej 73f86f9fe4 Add a DBSYM variable for the dbsym(8) host tool. 2001-11-09 07:30:55 +00:00
thorpej 147b1bdc1c Add some rudimentary support for ELF symbols in DDB on the ARM ports. 
On platforms which load the kernel sans symbols directly from firmware
(possibly in e.g. S-Record format), call ddb_init() with empty arguments,
so that it will search any compiled in SYMTAB_SPACE.  On all other platforms,
if __ELF__, also call ddb_init() with empty arguments until ELF bootloaders
which pass symbol information are ready.

lukem 704b08b696 Generally don't need the extra byte in MAXPATHLEN sized buffers, because 
pathnames are guaranteed by POSIX to be MAXPATHLEN-1 bytes long.
Kindly pointed out by Warner Losh in private email.
 2001-11-09 06:55:56 +00:00
thorpej 47514a31be Remove unneeded declarations of the db_machine_init() function. The 
ARM ports are the only ones that actually have one, and it is about
to change.

thorpej ca61e8a63a Support for building the new BFD-using dbsym(8) as a targeted host 
tool.
 2001-11-09 05:53:26 +00:00
thorpej aeeee8c24d New BFD-using dbsym(8) written by Simon Burge, with some code 
derived from the BFD-using mdsetimage(8).

TODO:
* Use loadfile(), rather than home-grown ELF parsing code (requires
  some changes to loadfile()).
* Support a.out like the gwr's dbsym(8) (this comes for free when
  we switch to loadfile()).

matt e85e9a59a1 Make this compile under ELF. 2001-11-09 05:31:44 +00:00
thorpej 3b569c7be3 * Fix a quoting error so that when using -n, we actually see 
$TOOLDIR and $DESTDIR in their expanded form.
* Set USETOOLS=yes in the make wrapper script; it's pretty pointless
  using the make wrapper unless you're using the host tools.
* In the -t case, make sure to only echo the "make obj" command if -n.

thorpej b72e770a8a IQ80310-specific setup for the i80312 Companion I/O chip driver. 2001-11-09 03:31:37 +00:00
thorpej 660b98b7dc Snapshot of work-in-progress for Intel i80312 Companion I/O chip; 
just basic Inbound and Outbound window setup is done, PCI configuration
space access (not quite working yet), and I/O and Memory space routines
so far.

reinoud 411b3e63cf Update it again *sigh* ... still trouble with my snapshot's ELF in building 
the ramdisc but eventually the all-ELF ramdisc got build by an a.out
system...
