rin | Style and cosmetic changes. No binary changes intended.
|
| 1.28 |
| 06-Jul-2020 |
rin | LKM was gone. _KERNEL is always defined for module.
|
| 1.27 |
| 24-Jan-2016 |
christos | expose __register32_t for frame.h
|
| 1.26 |
| 28-Feb-2014 |
matt | branches: 1.26.6;
Add trapframe32 for COMPAT_NETBSD32
|
| 1.25 |
| 01-Aug-2012 |
matt | branches: 1.25.2; 1.25.4;
Fix a problem where the kernel could randomly reset due to a watchdog event.
When an exception happens, the srr0 (exception PC) was being saved in the
normal location of the current callframe. This was fine except when the
routine was in its prologue after it had saved LR but had not yet updated the
stack pointer or when the routine was in its epilogue after it has restored
the stack pointer but not yet loaded the LR. In either case this would cause
the LR to be corrupted (either running the routine forever or by branching
to itself forever). Now we save and restore the contents of that memory
location so the corruption can't happen.
|
| 1.24 |
| 19-Feb-2012 |
rmind | Remove COMPAT_SA / KERN_SA. Welcome to 6.99.3!
Approved by core@.
|
| 1.23 |
| 20-Jun-2011 |
matt | branches: 1.23.2; 1.23.6; 1.23.8;
Pad out trapframe for OEA so that trapframe has identical sizes for all
PPC variants.
|
| 1.22 |
| 18-Jan-2011 |
matt | branches: 1.22.4;
Add support for BookE Freescale MPC85xx (e500 core) processors.
Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.
|
| 1.21 |
| 27-Nov-2009 |
rmind | branches: 1.21.4; 1.21.6;
- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
|
| 1.20 |
| 16-Oct-2008 |
wrstuden | branches: 1.20.16;
Bring back saframe. Noted by Robert Swindells.
|
| 1.19 |
| 09-Feb-2007 |
ad | branches: 1.19.44; 1.19.48; 1.19.54;
Merge newlock2 to head.
|
| 1.18 |
| 11-Dec-2005 |
christos | branches: 1.18.20;
merge ktrace-lwp.
|
| 1.17 |
| 27-Aug-2003 |
matt | branches: 1.17.16;
Move SFRAMELEN to frame.h and use it in vm_machdep.c. In setfunc, setup
callframe linkages correctly. Restore use of ldptr to locore_subr.S
[pthreads and gdb no longer crash/hang the system]
|
| 1.16 |
| 12-Aug-2003 |
matt | Cleanup/rework cpu_switch*, switch_exit, Idle routine. Remove pcb_psl
since it was write-only. When setting up a process, make sure the fake
callframes are properly linked together.
Only lower SPL when in Idle loop. Raise spl to previous level (which would
be IPL_SCHED) when exiting Idle loop. Never lower SPL anyplace else.
|
| 1.15 |
| 31-Jul-2003 |
matt | Change switchframe to use register_t (anything that uses stmX/lmX needs
to be defined as register_t).
|
| 1.14 |
| 03-Feb-2003 |
matt | branches: 1.14.2;
Don't use trapframe in sigcontext. Instead define a new structure
utrapframe that fixed in size (and the same size as the trapframe
in NetBSD 1.5). This preserves binary compatibility for those programs
that dealt looked at sigcontexts.
|
| 1.13 |
| 02-Feb-2003 |
matt | Perform a rototill of the powerpc code. Mandate use of SPRG0 to store
a pointer to current cpu's cpu_info structure. Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make
ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK
to std.<platform>. Change faultbuf to a struct instead of an array.
On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.
|
| 1.12 |
| 22-Jan-2003 |
kleink | MPC601 support bits:
* install 601-specific DSI and RUNMODETRC trap handlers
* save/restore MQ in trapframe, add MQ hooks to DDB
* extend battable to 512 entries to hold the 601's 8M translations
* instead of adding I/O to BAT starvation, set up segment registers
for Memory-Forced I/O Controller Interface Access
* sync after tlbie
|
| 1.11 |
| 19-Jan-2003 |
matt | Use CALLFRAMELEN instead of 16.
|
| 1.10 |
| 19-Jan-2003 |
matt | Add trapframe32 (for compat_netbsd32).
Add CALLFRAMELEN. (so we can remove many of the hard coded "16" or "15"
in the powerpc code).
|
| 1.9 |
| 18-Jan-2003 |
thorpej | Merge the nathanw_sa branch.
|
| 1.8 |
| 03-Nov-2002 |
matt | Change _MACHINE_foo_H_ to _POWERPC_foo_H_
|
| 1.7 |
| 24-Jul-2002 |
chs | rename the intr_depth field of struct intrframe to avoid a name conflict
in MULTIPROCESSOR builds.
|
| 1.6 |
| 18-Jul-2002 |
matt | Make sure that pmap_zero_page and pmap_copy_page don't make calls or
reference while relocation is disabled since the stack will be inaccessible.
Add support for using AltiVec in pmap_zero_page and pmap_copy_page on
AltiVec capable processors.
|
| 1.5 |
| 05-Jul-2002 |
matt | Peform a rototill over the powerpc-based ports.
Move the trap/vector initialization for MPC6xx ports to mpc6xx_machdep.c
Also move softnet, install_extintr, mapiodev, kvtop. Add common BAT
initialization code.
Add user Altivec support.
Fix calls to OF_call_method in macppc/macppc/machdep.c.
Use ci_fpuproc in cpu_info instead of separate fpuproc.
Add separate syscall.c and defined __HAVE_SYSCALL_INTERN.
|
| 1.4 |
| 21-Apr-2002 |
kleink | branches: 1.4.2;
Convert the spill stack frame to use symbolic offset names; inspired by
a conversation with Matt Thomas.
|
| 1.3 |
| 18-Apr-2002 |
matt | Use a common genassym.cf for all the PPC_MPC6XX ports. Add a makeoptions to
std.foo to indicate the directory to get genassym.cf from. Add an intrframe
to <powerpc/frame.h> and make trap_subr.S use symbolic offsets into it.

matt | Add SPE (signal processing engine) support for mpc85xx/booke. Think of it
as AltiVec-lite (really lite). Genercize AltiVec support so that it could
the same interface could support SPE as well. Rework the FPU support along
the same lines. Move the __asm() to their own XXX_subr.S (altivec, fpu, spe).

matt | intrframe is dead. Just use a partially filled trapframe.
Add a ktrapframe which include the cf_sp/cf_lr of the callframe in addition
to the trapframe. This allows the FRAME_XX+8 to just be FRAME_XX.
Cleanup and simplify.
