interrupt handlers into intrtab[] array, rather than the idea of devices
in 'psuedo' TURBOchannel slots.
- Nuke symbols for psuedo TC slots.
- Abandon never/unlikely used intr_disestablish()s.
consinit().
- Fix fbconnect() and relatives; 'struct fbinfo' is initialized only once,
making sure no extraneous console resolution message is emitted.
[nisimura-pmax-wscons] branch and suggestions from Toru Nisimura:
- Remove bogus tc_slot_info[] name for interrupt handling array
and replace with simplified struct intrhand intrtab[] array.
- Add intr_establish() and intr_disestablish() function pointers
to struct platform and initialise this in each model-specific
initialisation, and remove global tc_enable_interrupt function
pointer.
- Remove model-specific function declarations from ibus/ibusvar.h.
This is functionally identical to the current scheme, and doesn't
yet try to commonise interrupt establishment by bus type as the
[nisimura-pmax-wscons] branch does.
Also, move cpuspeed variable from autoconf.c to machdep.c
- Make local-only function and variables static.
- Move function prototypes and extern variable declarations to
header files.
- Delete unused variables.
There's still a handful of extern declaraions that should be fixed up.
stub for memsize_bitmap() to use the PROM bitmap for memory information.
Add a memsize function pointer to the platform structure, and make all
existing DECstation models use memsize_scan() for now.
Interestingly, from the Ultrix cpuconf.{c,h} only the 3100 and 5400 use
a memory scan to determine available memory - all other models use the
PROM bitmap...
- Rework ibus device configuration and interrupt handler assignment.
- Remove TC device exposure in 'mainbus.c'
- Squash 'ibus_{3100,5100}.c' into a file; it can not cope with 3max.
- 'struct confargs' -> 'struct mainbus_attach_args'
Now about to remove tc_slot_info[] and tc_enable_interrupt inherited from
4.4BSD.
HZ using high resolution timer circuit if available. Merge os_init
into the primary hardware initialization in sysinit[].init.
- Nuke an irrelevant attempt to disable RTC under splhigh condition.
- Make sure IOASIC DECstations accumulate device interrupt mask bits into
certain global variables.
- Have witchcrafts to issue ACK to RTC interrupt.
- Add a missing \n and a minor rearrangement in cpu.c
stand Makefiles already set up the compile environment so that
machine/loadfile_machdep.h can be found.
XXX: Not done for i386, mmeye or sparc - I can't test these at the
moment. It should be as simple as making a machine symlink
pointing to .<some number of ../'s>./include in the objdir...
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
- 'struct fbsoftc' created, which points to a 'struct fbinfo'
- 'struct fbinfo' for each device is allocated with fballoc()
This means:
- Console device doesn't get different 'struct fbinfo' at attach
- Console device doesn't get initialized twice
- Color rcons now works
- The current Xserver MUST BE REBUILT.
routines now reside in locore.S. No functional difference is expected.
- Replace abused splx() abuse with _splset() to change MIPS processor
interrupt mask bit. 'mips/trap.c' side will be fixed soon.
so that devices which must allocate DMA memory in this range (e.g.
PixelStamp graphics boards) have a better chance of doing so, without
an awful hack.
bootinfo record to 1kB (we are using less than 200 bytes now) so that it
doesn't run into addition PROM memory.
At 0x8001f00 the bootinfo record was stomping on some memory used by the
SFB cards for font information.
"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)
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
* add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h
(based on Alpha cpuconf.[ch], with a namechange to avoid clashes with
support for models of MIPS cpus. They differ more than Alphas).
* For each supported model of DECstation, create a separate file
with the support for that model. Use model codenames, since
support is really baseboard-specific and CPU daugherboards can change.
Move code from machdep.c and pmax_trap.c,
Add sysconf (nee "cpuconf") support.
* Rename model-specific functions to match sysconf names.
* Clean up autoconf.c. Use platform callbacks.
* Retire pmax_trap.c.
Leaves I/O bus configuration and console configuration untouched.
(_BYTE_ORDER, _BIG_ENDIAN, _LITTLE_ENDIAN).
Define old names from the ANSI ones if not _POSIX_SOURCE.
* Define _QUAD_HIGHWORD and _QUAD_LOWWORD properly when
_BYTE_ORDER == _BIG_ENDIAN.
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.
Add DDB interface to /sys/arch/mips/mips..
Rework heuristic stack traceback to work with DDB.
Add hooks to print exception log from DDB.
Add hooks from pmax console drivers: call Debugger()
after break from serial console, or 'DO' key from LK-xxx.
Move mips-specific pmap definitions (PMAP_PREFER for mips3, declaratin
of pmap_bootstrap() for the system-specific machdep.c) from
arch/pmax/include/pmap.h to arch/mips/include/pmap.h.
