rin | Style and cosmetic changes. No binary changes intended.
|
| 1.30 |
| 06-Jul-2015 |
matt | Don't clear PSL_FP/PSL_VEC
|
| 1.29 |
| 06-Jul-2015 |
matt | Add a check to make sure that if PSL_FP is set, we own the FPU.

matt | Typo
|
| 1.26 |
| 09-Mar-2014 |
matt | Make sure to clear PSL_SE before going to usermode on BOOKE
Revert back to testing PSL_SE in the trapframe and not mdlwp md_flags
|
| 1.25 |
| 09-Mar-2014 |
matt | Don't test for PSL_SE in tf_srr1 since will be cleared on the next exception.
Keep a copy of it in l_md.md_flags which will be preserved.
|
| 1.24 |
| 26-May-2012 |
matt | branches: 1.24.2; 1.24.4;
Add __HAVE_RAS support. Do it in userret.
|
| 1.23 |
| 17-May-2012 |
matt | Add an KASSERT to check that PSL_PR is always set.
|
| 1.22 |
| 27-Sep-2011 |
jym | branches: 1.22.2; 1.22.6; 1.22.8;
Modify *ASSERTMSG() so they are now used as variadic macros. The main goal
is to provide routines that do as KASSERT(9) says: append a message
to the panic format string when the assertion triggers, with optional
arguments.
Fix call sites to reflect the new definition.
Discussed on tech-kern@. See
http://mail-index.netbsd.org/tech-kern/2011/09/07/msg011427.html
|
| 1.21 |
| 20-Jun-2011 |
matt | Explicitly include <powerpc/psl.h>
|
| 1.20 |
| 02-May-2011 |
matt | branches: 1.20.2;
Move powerpc to use pcu to manage FPU/AltiVec/SPE.
|
| 1.19 |
| 19-Feb-2011 |
matt | Compare ci_veclwp against &lwp0, not NULL.
|
| 1.18 |
| 17-Feb-2011 |
matt | add begging of single step support. Since BookE doesn't support PSL_SE, if
userret find PSL_SE set in SRR1, it will call booke_sstep to setup the
debug registers.
|
| 1.17 |
| 18-Jan-2011 |
matt | branches: 1.17.2;
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.
|
| 1.16 |
| 21-Nov-2009 |
rmind | branches: 1.16.4; 1.16.6;
Use lwp_getpcb() on mips, powerpc and sh3, clean from struct user usage.
|
| 1.15 |
| 06-Nov-2007 |
simonb | branches: 1.15.18; 1.15.40;
Fix unused variable warning for the non-FPU/altivec case.
|
| 1.14 |
| 05-Nov-2007 |
ad | branches: 1.14.2;
Don't set l_usrpri / spc_curpriority here. mi_userret() does it.
|
| 1.13 |
| 16-Feb-2006 |
perry | branches: 1.13.24; 1.13.42; 1.13.44; 1.13.48;
Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.
As per core@.
|
| 1.12 |
| 24-Dec-2005 |
perry | branches: 1.12.2; 1.12.4; 1.12.6;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
|
| 1.11 |
| 11-Dec-2005 |
christos | merge ktrace-lwp.
|
| 1.10 |
| 16-Apr-2004 |
hannken | branches: 1.10.12;
Make it compile when PPC_HAVE_FPU is not defined.
|
| 1.9 |
| 15-Apr-2004 |
matt | Revamp how user MSR/SRR1 are dealt with.
Add a PSL_USEROK_P(psl) macro which valids the bits (replaces the use of
PSL_USERSTATIC).
Add a PSL_USERSRR1 mask which is used to mask out status bits in the upper
half of SRR1.
Make sure PSL_VEC is set appropriately in userret(). PSL_VEC is in the same
region as SSR1 status bits so it's not preserved on exceptions. Thus we
need to make to set it.
When returning a MSR/SRR1 to userland, always clear the status bits.
Add emulation of the mfpvr, mtmsr, and mfmsr instructions.
|
| 1.8 |
| 06-Apr-2004 |
matt | When seeing if the FP or VEC unit has been stolen by another process, check
PSL_{FP|VEC} instead of PCB_{FP|VEC}. The former will only be set if the
process owned the {FP,VEC} unit when it trapped into the kernel. The latter
would be set if the lwp ever used the {FP,VEC} unit.
|
| 1.7 |
| 04-Apr-2004 |
matt | When returning back to user mode, if the lwp has lost the FPU, not only
clear PSL_FP bit (to force a FPU Unavailable exception) but clear
PSL_FE0 and PSL_FE1 so that the FP execption mode is changes to ignore.
This will prevent spurious FP exceptions being made when the running lwp
doesn't own the FPU.
|
| 1.6 |
| 13-Feb-2004 |
wiz | Uppercase CPU, plural is CPUs.
|
| 1.5 |
| 31-Oct-2003 |
cl | Reduce code duplication by adding mi_userret() in sys/userret.h
containing signal posting, kernel-exit handling and sa_upcall processing.
XXX the pc532, sparc, sparc64 and vax ports should have their
XXX userret() code rearranged to use this.
|
| 1.4 |
| 18-Jan-2003 |
thorpej | branches: 1.4.2;
Merge the nathanw_sa branch.
|
| 1.3 |
| 08-Aug-2002 |
chs | branches: 1.3.2; 1.3.4;
it's PPC_HAVE_FPU, not PPC_HAS_FPU.
also, include the headers that turn on FPU and AltiVec features
in case no one else does.
|
| 1.2 |
| 06-Aug-2002 |
chs | branches: 1.2.2;
actually we shouldn't hold kernel_lock while calling postsig().
|
| 1.1 |
| 02-Aug-2002 |
chs | use a completely separate trap handler for syscall traps.
this reduces syscall overhead by 10% to 20% depending on cpu type.
|
| 1.2.2.6 |
| 26-Sep-2002 |
nathanw | Change "if (l->l_flag & L_SA_UPCALL)" to "while (l->l_flag & L_SA_UPCALL)"
in userret() functions or equivalent, to permit delivery of multiple upcalls
in a single kernel entry.
XXX It's getting crowded in here. Collapsing posting signals, upcalls, and
XXX kernel-exit handling into one mechanism would be nice.
|
| 1.2.2.5 |
| 09-Aug-2002 |
nathanw | Pull up PPC_HAVE_FPU fix.
|
| 1.2.2.4 |

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
