thorpej 3993ee01e4 Don't enable I/O or memory access here! These bits in the PCI CSR are 
set up by the firmware, and indicate which mapping types the system
supports.

thorpej ac0f626cca Make sure bus mastering is enabled. 1999-03-24 01:05:15 +00:00
thorpej 9f85a4a798 Make sure bus mastering is enabled. 1999-03-23 23:18:50 +00:00
jonb 6c6ff861c6 put in compiler options to reduce object size by half 1999-03-23 23:02:14 +00:00
thorpej bc5e782935 Don't rely on an `rcsid' being present. 1999-03-23 22:53:30 +00:00
simonb 729eda4324 Define a bootinfo record and initial structures that the pmax will use. 
Modeled on i386 and bebox bootinfo.h.
 1999-03-23 22:53:02 +00:00
simonb aca34380db If on entry the stack is within 4kB of _start, don't reset the stack 
pointer to just underneath _start.  Allows bootblocks (or other kernel
calling programs) to pass more than 4 arguments if it sets up the stack
properly.

The 4kB figure may be overkill - on the pmax it only needs to be a dozen
of so bytes.
 1999-03-23 22:43:18 +00:00
simonb 9913b7202b Revert SA_NOPUTCHAR - the pmax was the only port using it and the new 
pmax bootblocks provide a putchar().
 1999-03-23 22:25:31 +00:00
simonb c9e3b47a0f Don't build anything while bootblocks are being updated. 1999-03-23 22:23:11 +00:00
simonb f93b8168c0 Include <machine/db_machdep.h> instead of <mips/db_machdep.h>. 1999-03-23 22:15:36 +00:00
simonb 41febd3a3c Move DB_{AOUT,ELF}_SYMBOLS (and DB_ELFSIZE) definition to port-specific 
db_machdep.h file.
 1999-03-23 22:07:06 +00:00
simonb 027594b1eb Add CPU_BOOTED_KERNEL to CTL_MACHDEP definition. 1999-03-23 22:04:01 +00:00
thorpej 86f87d7c5f Add a new shared media option, IFM_FLOW, used to enable link-level 
flow control.  IEEE 802.3x is in mind, but this could be generally
useful for different types of media.
 1999-03-23 21:46:47 +00:00
drochner 1c99e4196a Use BUS_SPACE_ALIGNED_POINTER() instead of ALIGNED_POINTER() where the pointer 
in not just used to access memory but is bassed to bus_space_xxx_n()
methods. For debugging purposes, bus_space can have additional constraints
which will be properly met by BUS_SPACE_ALIGNED_POINTER().
 1999-03-23 21:41:07 +00:00
drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context, 
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

perry 1adf543079 update the date. 1999-03-23 21:19:58 +00:00
perry 23433d74a4 more updates. It appears, unfortunately, that the whole "gotchas while 
upgrading" section is going to need a rewrite.
 1999-03-23 21:17:44 +00:00
perry e2cf6728d9 add Piermont Information Systems 1999-03-23 21:12:56 +00:00
perry 27b5e4333f update for changes in main -- USB and IDE are not i386 specific 1999-03-23 21:02:09 +00:00
perry 58263c1e72 Numerous fixes for 1.4. This is approximately okay for 1.4 now, 
assuming enough people proof read it. more to come.

bad 23d89d53f3 config(8) glue for the TCIC PCMCIA backend. 1999-03-23 20:07:39 +00:00
bad f44fb0d91c A backend for Databook's TCIC family of PCMCIA chips. 
Thanks to Andreas Lohrum, O'Reilly Verlag, Terry Moore, and Holger Czukay
for hardware, documentation, and support.

mycroft 1bb64b0636 __SWAP_BROKEN is no longer useful here. 1999-03-23 19:16:03 +00:00
perry 75b15f7534 first cut of whatis for 1.4 1999-03-23 18:57:19 +00:00
mycroft 6bb727e736 Nuke some more code that was fetching PT_M and PT_H from pv_flags. 1999-03-23 18:39:38 +00:00
thorpej c939af8267 Oops, some source files use __IDSTRING() directly, so provide one in 
the ELF case, as well.
 1999-03-23 18:28:12 +00:00
drochner a9ddfb696d allow to set location of INSTALL kernel from command line so that 
bootfloppies can be built with r/o /usr/src or with other kernels
 1999-03-23 18:10:57 +00:00
wrstuden 3c8e65b670 Oops. macppc doesn't use PCLK as a baud rate source. 1999-03-23 18:07:19 +00:00
drochner ccb094136e find "mdsetimage" in ${DESTDIR} 1999-03-23 18:05:45 +00:00
mycroft 5f63cab877 The page and section fault handling paths are essentially identical, so 
combine them.  This also fixes a performance issue, in that we always
faulted pages twice in order to write them.
 1999-03-23 18:02:02 +00:00
wrstuden a7678930b4 Oops. mac68k does NOT use PCLK as a clock source, so don't enable it in 
the default channel setup.
 1999-03-23 17:55:03 +00:00
mycroft 79e56d3237 The ARM has the same copy-on-write bug as the i386 -- the write enable bit in 
PTEs is ignored when in kernel mode.  Hack around this just like we do on the
i386, by adding a prepass to copyout() to check for write permission on the
destination pages.

drochner 5575305f99 If no screen got the "focus" (which happens with serial console or if 
the current screen is deleted), automatically give focus to the next
screen created. Saves the need to switch to a usable screen manually.

christos f36829e285 s/DEBUG/LDT_DEBUG/ This got too verbose when running Wine. 1999-03-23 15:48:19 +00:00

bouyer 491d912f59 Implement a read cache, as announced on tech-userlevel. Default is 32k 
read buffer size, 512 buffer or 15% of the user memory. Can be changed
with the -k and -s options.
 1999-03-23 14:22:59 +00:00
mycroft 8f3d31a32b More cleanup... 
* Don't bother pulling PT_M and PT_H bits from pv_flags; they can't ever be
  set there!
* Actually make pmap_clear_reference() do something useful.
* Also set the referenced bit (PT_H) when emulating a write fault.
 1999-03-23 13:52:48 +00:00
mycroft da99fe308e Repeat after me: 
If we're doing modified bit emulation, we must revoke write permission in
pmap_clear_modify().  This is non-negotiable.  I will revoke write permission
in pmap_clear_modify(), or suffer the wrath of a thousand bricks.
 1999-03-23 13:27:48 +00:00
mycroft 3c8512dbb5 We could not possibly have been updating the pv attributed correctly in 
pmap_enter(), so... make the obvious change.

pk b0de87c45f To clear a chunk of bus memory use bus_space_set_regionN(). 1999-03-23 12:01:45 +00:00
mycroft b88d12625c Fix the `missing footer' problem. See the comment for details. 1999-03-23 11:50:09 +00:00
lukem 0a10e5dd4b document new bind() restrictions 1999-03-23 10:59:11 +00:00
lukem 8a931fcdd8 Ensure that you can only bind a more specific address when it is done by the 
same uid or by root.

This code is from FreeBSD. (Whilst it was originally obtained from OpenBSD,
FreeBSD fixed it to work with multicast. To quote the commit message:
    - Don't bother checking for conflicting sockets if we're binding to a
      multicast address.
    - Don't return an error if we're binding to INADDR_ANY, the conflicting
      socket is bound to INADDR_ANY, and the conflicting socket has
      SO_REUSEPORT set.
