on an Ultra 2 and works fine, apart from formatting which is known
to be broken. It failed to work on an ebus machine. The ebus
support compiles fine, but I don't have hardware for testing. This
code is based on the sparc driver with hints from OpenBSD on how
to do the sbus and ebus attachments, along with help from martin@
and mrg@.
Initial commit approved by martin@
TODO:
- fix ebus support
- fix XXX issues
- check resource deallocation
- fix formatting
- merge remaining differences from sparc driver
- split out back end chip support
- have sparc driver use new common back end chip support
- adapt to newlock when branch is ready
- adapt to "disk-info" property dictionary
- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.
This address kern/18407
On amd64, sparc64, i386, and alpha, they will be compiled in and disabled
by default. That means that to use them you either enable the "global"
knob with sysctl, or use paxctl(1) to enable it on a per-program basis.
On sparc and macppc just include a commentd out line in the GENERIC kernel.
and tables to map fimware names to driver names. Based on a suggestion
from Eduardo (quite some time ago).
Each device (on busses we can handle and care about) gets a device property
storing the devices OpenFirmware package handle. To match the boot device,
the phandle of the chosen bootpath is compared against this property,
plus some additional string matching for disk/cd devices (where OF only
provides a node for the device class, not each instance).
- add a new entry point for idle called idle_switch that is called by
cpu_switch() in the MP case when sched_whichqs is zero, properly
setting up the idle stack. from petrov@ via martin@.
- for the IPI case, avoid loading the address of intrlev into %g3
- remove some NOT_DEBUG code
- load the interrupt argument #2 in the delay slot
this removes 2 nops during interrupt processing for the normal
case, and an additional 2 ALU instructions for IPIs
- initialise bootcpu->ci_{cpcb,initstack}/proc0paddr from the
idle u area.
pmap_extract():
- make this work on the kernel interrupt stack as well
both of these are from petrov@ via martin@.
pmap_update(): XXX mark the MULTIPROCESSOR call to smp_tlb_flush_all().
so replace a branch with a 'sir'
- in #if 0 code, in sparc64_ipi_flush_pte() and sparc64_ipi_flush_ctx()
save/restore the out registers that the sp_tlb_flush_xxx() versions
around calling them
- in sp_tlb_flush_pte() and sp_tlb_flush_ctx(), replace global register
usage with out registers so that we don't clobber the (alternate)
global registers when these are called from IPI context
- reload %fprs for checking it again.
- use symbolic names for checking in %fprs.

cache a copy of the fprs so we know what fp restore we should do after

use symbolic names for checking in %fprs, as above

fix a couple of %y register save/restore errors
1) don't save %y in a register that is later used before restoring %y
2) always restore %y after calling a signal handler
tested by drahn@, OK pval
