gmcgarry bdd225baa1 Add a blurb to the top of all GENERIC files. This serves three purposes: 
- to clarify some terminology
- to clarify the intention of the GENERIC file
- to cross-reference some useful man pages
 2001-12-14 05:34:45 +00:00
chs 2dfd15933e change the reference-counting of PT pages to start from zero instead of 
one, so that we don't mess up the global count of wired pages by having
the page's wire_count be non-zero when we free the page.
pointed out by Michael Hitch.

Otherwise the appropriate MKxxx=no won't be defined .

atatat b45c51b1fc Roll the rest of the ports over to the new MI kernel build machinery. 
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

kleink e5341ee40f No point in installing svr4_machdep.h. 2001-11-28 13:14:12 +00:00
lukem ecb81c3f6d - convert usage of "defopt" to "defflag" where the relevant option does 
not support a value (e.g., it's to be used as "options FOO" instead of
  "options FOO=xxx"). options that take a value were converted to
  defparam recently.
- minor whitespace & formatting cleanups

fredette f0002ba642 Added macros for the bits in the SYSBUS byte, and macros 
for the i82596 PORT access interface, from the documentation
for that chip.  These help clarify writes to the SYSBUS
part of the SCP, and PORT usage by i82596-aware drivers.

chs 621a9ec9ea allocate and free page table pages explicitly instead of abusing 
uvm_fault_wire().  this allows us to make pt_map non-pageable,
but we need to be careful in pmap_remove() not to attempt to
reference PTEs after the PTP has been freed.

soren 662f877587 MAXSLP is defined to be a machine-independent scheduling parameter,

scw 45e7238a02 Bump the version numbers of all bootloaders which use loadfile_elfXX() now 
that it tries hard to avoid backwards seeks.

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...

scw 61fd713a11 Commit a change I've had lying around for a while: Initialise wired 
PTEs with `PG_U' to avoid them being needlessly updated when first
accessed.

thorpej 66f972ab70 Need byteorder.c for loadfile_elf*.c 2001-10-31 21:39:02 +00:00
thorpej e727e3f180 Split elf32 vs. elf64 handling in loadfile(), including support for 
each separately and explicitly.  BOOT_ELF is now BOOT_ELF32 and
BOOT_ELF64, and ELFSIZE should no longer be defined in loadfile_machdep.h.
 2001-10-31 17:20:45 +00:00
thorpej 4810d73020 Build the loadfile() a.out, ECOFF, and ELF back-ends as separate 
objects.

jmc 6d536163de Change defaults for kernel compiles. Default all to USETOOLS?=no and have 
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

thorpej ba217c4196 Set MACHINE_ARCH explicitly in Makefiles for which it is constant. 
Also, since config(8) now explcitly sets MACHINE, there is no need
to do it here in the Makefile.

scw f6e6d32172 Use the entry-point returned from the first call to loadfile() 
instead of the one from the second call (which has a non-zero
offset included in it).

Fixes port-mvme68k/14292 from Ken Seefried.

chs f013b5beb1 fix pmap_changebit() to look for the bit in the page attrs 
in addition to any PTEs.  fixes PR 14197.

chris 0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

in vunmapbuf(), call pmap_*remove() explicitly since uvm_km_free_wakeup()
will soon no longer do it for us.

scw e9261b9f13 Time Keeper NVRAM driver. 2001-08-12 18:34:25 +00:00
scw bb210bda7e Split the nvram/rtc functionality away from the clock interrupt code 
and attach it as `timekeeper0 at mainbus0'.
Use the MI mk48txx nvram/rtc access functions instead of home-grown
versions.

It should now be very easy to add a character device for the benefit
of userland access to NVRAM.

but it's better late than never.

scw da3836f00d Flush the caches in pmap_remove_mapping() when PRM_CFLUSH is specified. 
Also, flush the ATC for the page in pmap_kenter_pa() after setting up the
mapping. With any luck this last one might just solve the 060 problems I've
been seeing...
