- Build an ECOFF version of the bootloader as "boot". As a temporary
measure (due to a bug in libbfd which has not yet been fixed, but
for which a work-around exists as a patch), install and ELF version

the toolchain issue is resolved.
Don't make clean and cleandir depend on the lib subdir.

that anyone installs over HIPPI either. On the other hand, lots of people
would like to be able to install over their wireless networks or with their
Tigon Gig-E cards: so, let's synchronize this file's contents with the
modern world (at least a little bit).
Note that we really need to decide whether, as they used to be, the INSTALL

be GENERIC with some lines commented out. Using both styles is bad, but I
haven't fixed it in this commit.
contain information suitable for allowing other parts of the kernel
to determine if a memory region is aligned to the largest data cache
line size present in the system.
Add a mips_dcache_compute_align() function which must be called whenever
one of the data cache line size variables is changed, in order to
compute mips_dcache_align and mips_dcache_align_mask.
Refuse to clear the modified bit on a page if it has a writeable kernel
mapping. I'm not sure this is the right thing to do, but since further
writes to the page won't set the bit again, it's safer than clearing it,
and makes NFS writes work properly.
Add debugging code for modified-bit emulation, which checksums
allegedly-unmodified pages to see if they're _really_ unmodified.
Disabled by default because it's slow.
In the process, fix a bug in pv_release whereby the modified bit for a
page got cleared when its last mapping was removed. This seems to finish
the NFS write fixes started by the first change above.

this insn is available only on ARM arch v3 and later (and 2a). We
don't expect to be using these ops in the kernel on processors too
old to have SWP, and for userland uses (in e.g. a pthread library),
the kernel will simply have to trap and emulate the insn (it needs
to be "atomic", so a kernel trap of some sort will be necessary on
such platforms anyway).
the expensive checks are skipped when (!DEBUG&&!PMAPCHECK) and all of the
light-weigth checks are skipped when (!DIAGNOSTIC&&!DEBUG&&!PMAPCHECK).
This bring pmap.o's text down from 21KB (with PMAPCHECK) to 18.5KB (DEBUG)
to 16KB text (!DIAGNOSTIC).
the Branch Target Buffer of the BPRD bit changes.
* Enable Branch Prediction on the XScale by default.
* Don't invalidate the Branch Target Buffer explicitly. the i80200
manual (section 5.1, Branch Target Buffer Operation) notes that
manual software management of the BTB is unnecessary; it is flushed
implicitly when:
* processor resets
* FCSE process ID is written
* I-cache is invalidated
* sa110_cache_purgeD() is the same as sa110_cache_cleanD() on the
SA-1 -- make it an alias.
* sa110_cache_syncI() and sa110_cache_purgeID() are identical to
sa110_cache_cleanD() on the SA-1, with the exception that the
I-cache must also be flushed. Save code duplication by moving
the I-cache flush before the D-cache clean and letting it fall
through.
the platform supplies a clkread function that does something other than
return 0 (which is the default unless overridden by the platorm code).
Supply such a function for the IP22; even if it isn't perfect, it goes
a long way to making ntp usable.
While I'm at it, move the ticks-per-hz variable out of the struct platform
since it's really private to the per-platform interrupt/clock code.
XXX: No clkread function supplied for IP32, since it has other problems --
like a hardcoded ticks-per-hz, but the same code as on the IP22 could be
used.
* Define a CPWAIT macro as described in the i80200 manual and use it,
rather than replicating the code in a few places.
* The i80200 manual notes that the line-allocate operation used to
do global D$ clean does not actually perform a load/fill request
from external memory, and thus does not actually place valid data
in the cache lines allocated. Require that machine-dependent code
allocate an appropriately-sized chunk of unmapped VA space for the
global clean operation in order to avoid unpredictable results.
* The i80200 manual notes that the VA range for the Mini-Data global
clean (which *must* be mapped to physical memory) must be reserved
exclusively for cleaning the Mini-Data cache. Require that machine-
dependent code allocate an appropriately-sized chunk of memory for
this purpose.
pages, we use the standard (4K) page size as PAGE_SIZE. Make the
PAGE_SIZE related variables compile-time constants that reflect this.
Results in a bit over 2K worth of .text savings, and visibly better
code in the places that use PAGE_SIZE, etc.

- Full support for SCSI-2 Tagged commands (enabled by default)
- Implement save and restore datapointer messages
- Formalize interface between MI and MD drivers.
- decouple interface between MD driver and DMA routines
- Use scsipi layer where appropriate (Tags, Sync Negotiations etc)
- control blocks stored using kernel pool(9) functions
- evcnt(9) compliant counters
- Enable advanced features on later WD33c93 chips.
(Identify message out phase is hardware assisted)
- Improved timeout support (one per active control block)
- Improved MESG_IN and MESG_OUT handling
- Start to tidy up debugging output
- Numerous bug fixes and cleanups throughout
Changes are based largely on the NCR53c9x MI driver for ideas on
how to DTRT.
DMA via the Secondary Inbound window, for now. Will probably
need to revisit this at some point.
Require that the board-specific i80312 front-end slice off a
subregion for the memory controller before calling i80312_attach(),
and fix a bug in the IQ80310 front-end that caused the Secondary
Inbound window to be configured incorrectly.
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.
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.
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.
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.
PCI I/O spaces, as well as the i80312 PMMRs. Map these regions
in early bootstrap along with the on-board device address space.
* Adjust call to i80312_sdram_bounds() for the new way the PMMRs
are defined in i80312reg.h
* Word around some serious braindamage in RedBoot -- RedBoot uses
the on-board Ethernet to TFTP the kernel image. However, it does
not stop the Ethernet before transferring control to the loaded
program. This means that if it happens to receive another packet
(broadcast/multicast/unicast), it will happily scribble over the
memory of the new running program. Work around this problem by
performing a secondary-bus-reset on the i80312's PPB. XXX This
could be problematic if we ever encounter an application where
the i80312's PPB is actually used as a passthrough PPB.
interrupts.
This allows hardclock() to account for the time spent in interrrupts, and
as a side-effect, top(1), systat(1) and others will no more report 0% of
interrupt activity.
mvme68k does that already.
