tsutsui cb383cb5db Define MSGBUFSIZE here only if it's not specified by options(4). 2002-06-28 17:40:20 +00:00
briggs 1b3d605b4e Remove complaint: bus_dmamap_destroy() called for map with valid 
mappings bus_dma(9) states: "In the event that the DMA handle contains
a valid mapping, the mapping will be unloaded via the same mechanism
used by bus_dmamap_unload()."  And some drivers do mean to skip the
unload step.

matt 3043c05326 Add common routines to do BAT initialization, trap vector setup, 
interrupt vector installation, VM initialization, core-dumps (stubbed),
and network soft interrupts.  Also kvtop and mapiodev.

matt f7a6553147 Add common syscall dispatcher. Also put child_return in here. 2002-06-28 02:30:06 +00:00
matt 511223b674 If ALTIVEC is not defined, treat EXC_VEC|EXC_USER exceptions as PGM 
exceptions.  [Note that we still can't trap these due to issues in
trap_subr.S which are (yet) fixed]

matt cd85109523 Make traps even smaller by noticing the checking of privilege mode and 
use of curpcb/USPACE is common and move that into the common trap processing.

matt 1a5c0cf685 When not using the OLD pmap, bump kernel KVA space to 512MB (OLD pmap stays 
at 256MB).

matt 7a12a9737c Revamp how SR(s) are loaded on the user/kernel boundary. We now load all 
16 SR registers when transitioning between kernel and user.  Also, don't
reload the kernel SR(s) on every trap but only on traps from user space.
Instead of loading magic SRs for the kernel, load the kernel SRs from the
kernel_pmap_.  This makes trap_subr.S completely ignorant of SR uses and
so they can change with having to change trap_subr.S.  Also note that
since the user and kernel get complete SR sets, user VA space can now be
increased to 4GB if desired.
 2002-06-26 01:14:45 +00:00
matt 7c77963b01 Set SR_PRKEY for user pmaps. For the kernel SR(s) set SR_SUKEY|SR_PRKEY. 
Note that we never use a PTE PP of 0 or 1 (supervisor protection) so the
"key" is basically unused.  However, use SR_PRKEY for user space is
conceptionally the right thing to do.  Currently the kernel_pmap SR(s) are
ignored but that is going to be fixed shortly.

thorpej f89b062ae7 During native signal delivery (and iBCS2, since it uses the native 
sigcode), arrange to have the signal handler invoked directly, using
the trampoline only for the return path, saving a call insn.  Play
some other stack trickery in the trampoline to turn 2 pushl's into
one movl.

thorpej 4c0113def4 Swap the order of the sigcontext and hardware state in the sigframe. 2002-06-23 21:31:12 +00:00

thorpej 9cb2f482f0 When delivering a signal, arrange to have the handler invoked directly, 
using the trampoline only for the return.  This saves two instructions
in the trampoline, one of them being a branch.
 2002-06-23 19:16:43 +00:00
thorpej 7f7f0f86bd When delivering a signal, arrange for the handler to be invoked 
directly.  The trampoline is now used only for the return, and
makes it another 2 instructions shorter.
 2002-06-23 18:49:33 +00:00
thorpej 508e2dcf41 When delivering a signal, don't push the signum, code, and context pointer, 
or handler onto the stack.  Instead, just stuff them into the correct
argument registers (handler is a "4th arg").

perry 90062e3f5d Remove (completely unused) definition of CLK_TCK. Nothing in the 
kernel uses it, it is protected by _KERNEL, and it conflicts with the
definition in userland.
 2002-06-23 17:07:58 +00:00
perry fc9464af40 remove definition of CLOCKS_PER_SEC protected by #ifdef KERNEL. It is 
used nowhere, and KERNEL is defined nowhere (vs. _KERNEL).

mrg 9dcb300af2 finish previous; it would be nice if people were to use the lovely 
cross compiling mechanisms we have when making sweeping changes...
