skrll | Sprinkle some comments about ENABLE_ALIGNMENT_FAULTS leaving curcpu in r4
and curlwp in r5
|
| 1.25 |

skrll | branches: 1.25.8;
Trailing whitespace

chs | branches: 1.24.6;
split PUSHFRAMEINSVC into two pieces so that we can insert some additional
instructions in the middle in undefinedinstruction_bounce, namely to add
some additional space on the stack before the trapframe for undefineds from
SVC mode. this extra space allows dtrace to emulate a "push" instruction.
the initial version was from me and some improvements were from nick.
|
| 1.23 |
| 21-Jun-2015 |
matt | Remove duplicate ASEND(undefined_entry)
|
| 1.22 |
| 13-Mar-2014 |
matt | branches: 1.22.6;
Add clrex when we get an abort.
Simplify undefined_entry to use the undefined stack to do transfer to the
undefined handler.
|
| 1.21 |
| 05-Mar-2014 |
matt | push/pop unsaved registers before using printf.
|
| 1.20 |
| 02-Dec-2013 |
joerg | Don't use cpsr_all/spsr_all with mrs, it doesn't take a mask.
|
| 1.19 |
| 18-Aug-2013 |
matt | Move parts of cpu.h that are not needed by MI code in <arm/locore.h>
Don't include <machine/cpu.h> or <machine/frame.h>, use <arm/locore.h>
Use <arm/asm.h> instead of <machine/arm.h>
|
| 1.18 |
| 12-Sep-2012 |
matt | branches: 1.18.2;
Make sure the handler addresses are 32-bit aligned.
|
| 1.17 |
| 29-Aug-2012 |
matt | branches: 1.17.2;
Don't use locations in .data to store exception temporaries, use decidicated
space in cpu_info instead. This also moves undefined_handler_address into
cpu_info as well.
Use the new armreg* inlines for getting TPIDRPRW register.
Add MULTIPROCESSOR version of CPU_INFO_FOREACH
|
| 1.16 |
| 27-Apr-2008 |
matt | branches: 1.16.18; 1.16.34; 1.16.42;
Merge kernel changes in matt-armv6 to HEAD.
|
| 1.15 |
| 19-Jan-2008 |
chris | branches: 1.15.6; 1.15.8; 1.15.10;
Remove arm support for IPKDB.
It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.
|
| 1.14 |
| 11-Dec-2005 |
christos | branches: 1.14.46; 1.14.50; 1.14.52; 1.14.58; 1.14.66;
merge ktrace-lwp.
|
| 1.13 |
| 31-Oct-2003 |
scw | branches: 1.13.16;
Overhaul arm32's abort handlers:
- Assume a permission fault is always the result of an attempted
write, so no need to disassemble the opcode.
(as discussed with Richard Earnshaw/Jason Thorpe a week or two ago)
- Split out non-MMU data aborts into separate functions, and deal
correctly with XScale imprecise aborts. Specifically, the old code
made no attempt to handle the double abort faults which can occur
as a result of two consecutive external (imprecise) aborts. This
was easy to provoke by read(2)ing from a /dev/mem offset which caused
an external abort. With the old code, this would bring the system
down instantly, with little clue as to why. (hint: tf_spsr held
PSR_ABT32_MODE...)
- Re-write badaddr_read() to use pcb_onfault instead of adding extra
overhead to data_abort_handler(). A side effect of this is that it
now benefits from the XScale double abort recovery.
- Invoke the cpu-specific prefetch/data abort fixup routines only if
the host cpu actually needs it. On other cpus, the code is optimised
away.
- Sprinkle __predict_{false,true} in all the right places.
- G/C some excess debugging baggage.
|
| 1.12 |
| 30-Oct-2003 |
scw | Move the alignment fault enable/disable code into macroes to avoid
needless duplication.
Additionally, merge AST handling into the same code.
exception.S and the generic irq_dispatch.S routines have been updated
to use the macroes.
XXX: I have patches for the non-generic IRQ dispatch routines, but they
need testing by someone with hardware.
|
| 1.11 |
| 26-Oct-2003 |
scw | Assume that if curpcb is NULL, we're already running with alignment
faults enabled.
|
| 1.10 |
| 25-Oct-2003 |
scw | Skip the alignment fault enabling code if we came from SVC mode. It's
already enabled in this case.
|
| 1.9 |
| 25-Oct-2003 |
scw | Enable alignment faults on arm32 for both kernel and userland.
If COMPAT_15 and EXEC_AOUT are defined, support per-process
alignment checking where AFLTs are always enabled when running
kernel code and userland ELF binaries, and dynamically disabled/
enabled when switching to/from a.out binaries. This is necessary
in order to execute older a.out binaries, where gcc made
deliberate use of misaligned loads under certain circumstances.

wiz | branches: 1.8.2;
interrupt with two rs.
|
| 1.7 |
| 13-Oct-2002 |
bjh21 | Instead of "add rd, pc, #foo - . - 8", use either "adr rd, foo" or (where
appropriate) "mov lr, pc". This makes things slightly less confusing and
ugly.
|
| 1.6 |
| 15-Aug-2002 |
briggs | * Use local label names (.Lfoo vs. (Lfoo or foo))
* When moving from cpsr, use "cpsr" instead of "cpsr_all" (which is
provided, but doesn't make sense since mrs doesn't support fields
like msr does).
|
| 1.5 |
| 17-Jan-2002 |
bjh21 | branches: 1.5.8;
Separate out syscall() out into three parts:
swi_handler() does stuff that all SWIs will need, then calls
curproc->p_emul->e_syscall.
syscall() handles native NetBSD system calls.
linux_syscall() handles Linux system calls.
|
| 1.4 |
| 14-Jan-2002 |
bjh21 | Simplify SWI entry: syscall() now extracts the SWI comment field itself.
|
| 1.3 |
| 20-Dec-2001 |
thorpej | * Share a common vector page between arm26 and arm32.
* Use a common set of exception handlers for all arm32 platforms.
* New FIQ framework based on discussions with Ben Harris, shared
between arm26 and arm32.
|
| 1.2 |
| 28-Nov-2001 |
thorpej | - Garbage-collect some unused cruft.
- When processing ASTs, restore interrupts *after* clearing astpending.
