martin 8772c68807 Rename the DIV0 traps to avoid confusion with the usage on the sparc 
port: T_IDIV0 is the hardware trap generated on integer division by
zero, T_DIV0 is the software trap used to signal the same event.

This makes 32 bit kernels able to run sparc code with the v7 multiply/
divide library.

Spotted by Valeriy E. Ushakov.

matt b03d17694a Do a preliminary switchover of the mach code to lwp's. It compiles now 
but probably doesn't work.   That's for someone who understand this code
better.

scw 0767992461 If we don't explicitly recognise the trap type, only panic if it 
came from kernel mode. Otherwise, print details of the exception
and send a SIGILL to the process.

The is necessary now that debug exceptions are handled here.
 2003-01-20 22:32:26 +00:00
scw 80284bdc34 Arrange for non-panic debug sync/async exceptions to re-vector through the 
real sync/async exception handler instead of always calling panic_trap().
Otherwise, userland BRK instructions can halt the system.

pk 26eedde15b srmmu_cache_flush: when flushing per-page and doing more than one page, 
we might be crossing a segment boundary.

pk d823499ff4 pmap_enter4m: when installing a new PTE we don't need to invoke the elaborate 
TLB de-map protocol.  In the relatively infrequent case where this function
must update an existing mapping, do the de-map explicitly before installing
the new PTE value.

pk ab9a8ae184 Set the system-wide cache aliasing distance according to the largest cache 
found on the CPU modules (hypersparc & cypress).

Vikings have a physically indexed cache, so don't bother with computing an
aliasing distance (leaving cache_alias_dist zero disables the BAD_ALIAS macro).

pk b4a0aebea2 Add SUN4D case for cache alias macros. 2003-01-20 21:43:38 +00:00
aymeric 32571dfb87 fill in the dv_unit field of the fake "struct device" correctly. 
In particular, this makes grfN, N != 0, work as console.
Tested by Ignatios.

pk 353e527861 Remove the restriction that the boot CPU must be the first CPU in the order 
as it is presented by the PROM. This is actually amazingly less trivial
than it looks at first, since the finding the Module ID that's currently
executing your code is specific for each module type and/or manufacture.

matt fb891b41f5 Add _REG_foo to ppc mcontext and use them instead of constants. 2003-01-20 00:53:55 +00:00
rafal c1ff3ce973 Fix a bug that would cause the PCI fixup to assign addresses beyond the range 
of KSEG0/1 mappable PCI window (the MEG_ALIGN macro was aligning to *16* MB
instead of *1* MB due to an extra 0 in the round-to constant).  Also, allow
the PCI code to fix up all functions of a multifunction device; both from
Chris Sekiya, with a bit of massaging by me.
 2003-01-19 23:08:54 +00:00
rafal 48eb4573c0 Parse out flags passed to the kernel on boot; from Scott Taylor, tweaked to 
use the MI boot_flags.h interface by me.

From Johnny Billquist.

rafal 6c79dcd0e4 Update to use the full DS1687 register set, therefore allowing the clock to 
store absolute year rather than an offset -- this means the clock is now
consitent across the ARCS PROM, IRIX and NetBSD.

XXX: This attachment is now a mismoner, since it's a Dallas Semi RTC, not
a Motorola RTC.  Should be renamed.

rafal 0c4b06c362 Add pci/usb/audio devices; from Chris Sekiya. 2003-01-19 22:23:03 +00:00
rafal 537bf9a526 Change DS1286 definitions to start with DS1286_ rather than DS_ so these and 
DS1687 definitions are easier to distinguish.

This gets the Cayman to multi-user with a non-SA aware userland.

scw 8b92aecb3f Use the full 'sh5le-unknown-netbsd-' prefixed toolchain names, and
