mark ae0af9300a Fix a bug in irq_release() when searching interrupt list for the handler
to remove. The address of the pointer rather than the address of what
is pointed to was use to track the previous handler resulting in problems
when releasing a chained irq. (from John Ballance)

mark 9065e731d6 arm32 kernel source retructure
- New versions of the drivers for the devices that really are IOMD
    specific. The old arm32/mainbus drivers have either been rewritten
    and are now child devices of the IOMD or they have been restructured
    and split into generic drivers will IOMD specific attachments.

mark 480bd07ef8 arm32 kernel source restructure
- IOMD specific clock support. This used to the the generic ARM clock
    support but is now specific to the IOMD device.
  - Updated to support new IOMD device etc.

mark 06d8713b3d arm32 kernel source restructure.
- IOMD specific interrupt handling. These files are mainly the old
    arch/arm32/irq* files moved here and updated for new iomd device etc.
    (revision history maintained).

mark 59b6709696 arm32 kernel source restructure

    architectures that use an IOMD.
  - Configure all IOMD child devices based on the IOMD type and features.

mark 187f8c7c3d Remove local definitions of macros to push and pull trapframes and instead
include machine/frame.h to get these definitions.
1997-02-10 03:50:53 +00:00
mark e626201c12 Adopt as standard, the instruction sequence for storing the trapframe that
includes the workaround from the SA110 STM^ bug. This allows one piece of
code to be used to store the trapframe on all CPU types.

perry b89a3425b7 Eliminate obsolete TIMEZONE and DST options.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

mark fd643704d1 Minor changes (inline -> __inline)) 1997-01-06 04:47:53 +00:00
mark bc3f67bb21 Use the irqblock array to provide the information about which interrupts
should be blocked for each irq currently asserted.
1997-01-06 02:35:46 +00:00
mark c87f4e3785 Added the functions intr_claim() and intr_release(). These are front
ends for irq_claim() and irq_release() that will allocate and free
memory for the irqhandler structure.
Added an irqblock array that provides a quick reference to all the
interrupts that should be blocked when a particular interrupt is
received. The irq_claim() and irq_release() functions now update the
irqblock array.
1997-01-06 02:30:21 +00:00
mark ad3eed8ce3 Fixed PPP soft interrupts.
Make sure soft interrupts are only every delivered when the interrupt
depth is 1.
1996-12-27 02:01:02 +00:00
mark 9c855e4d1b Provide alternative trapframe push and pull macros from the StrongARM.
These alternative macros have a workaround for the STM^ bug in revision < 3
StrongARM CPU's that causes incorrect register saving if a cache line fill
is in progress during the STM.

mark 5debc61be1 Added IOMD_ID macro to return the 16bit IOMD ID code. 1996-11-23 03:21:43 +00:00
mark 092bb4bd47 Fixed type its NPPP not PPP. 1996-11-06 18:18:41 +00:00
mark 7824cc4e83 Added definitions of the IOMD DMA registers. 1996-10-29 23:14:34 +00:00
mark 81f6df323e *Major* rewrite, long overdue.
The irq delivery code has been rewritten. On entry to the irq vector the
processor is switched to SVC32 mode so all interrupt routines now run
in SVC32 mode rather than IRQ32 mode. This fixes lots of irq re-enabling
problems.
Interrupt latency times are now vastly improved for high priority interrupts.
Cleaned up calling ast() before returning to USR32 mode (don't need to
mess about with trapframe copying.
Cleaned up all the comments and sorted out their indentation.
Rewritten the soft interrupt delivery code.
Added generic ARM7500 support rather than just RC7500 support.
1996-10-15 23:20:40 +00:00
mark c77f36a38a Idented comments correctly.
Fixed bug in microtime() that could result in incorrect microsecond
adjustments.
