in question, whereas the ARM code was using it to hold the model
identification. To fix this, rename:
ci_cpuid -> ci_arm_cpuid
ci_cputype -> ci_arm_cputype (for consistency)
ci_cpurev -> ci_arm_cpurev (ditto)
ci_cpunum -> ci_cpuid
This makes top(1) give correct CPU numbers in its "STATE" column (all 0 for
now).
invalidation after every lock to ensure that changes made by other CPUs are
visible. This has nasty performance implications, but it does allow my
Hydrated Risc PC to run printf() on all its CPUs at once without corrupting
the message buffer.
and boot multi-user on a single-processor machine. Many of these changes
are wildly inappropriate for actual multi-processor operation, and correcting
this will be my next task.
based systems. Untested on shark, but is the right thing to do. I suspect
the original arm32 intr.h had the bug, and when the ports split we just took
the bug.
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
counters. These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.
pmc(9) is meant to be a general interface. Initially, the Intel XScale
counters are the only ones supported.
internally). Move arm/iomd/pms* to arm/iomd/opms*. Mechanical change,
tested by cross-compiling a kernel from i386.

XXX: What are arm/arm32/conf.c and arm/include/conf.h good for?
Note that this has been compiled on some systems, cats, IQ80310, IPAQ, netwinder and shark (note that shark's build is currently broken due to other reasons), but only actually run on cats.
Shark doesn't make use of the functionality as I believe there has to be a correlation between OFW and the kernel tables so that calls into OFW work.
MACHINE_ARCH since <arm/param.h> already sets it correctly to "arm".
* For platforms which are not yet ELF, defined MACHINE_ARCH to "arm32"
if __ELF__ is not defined by the C preprocessor.
* In <arm/param.h>, clarify the rules about when MACHINE and
MACHINE_ARCH are defined, and to what. Also, for ELF platforms,
int the non-_KERNEL case, force both MACHINE and MACHINE_ARCH to "arm",
rather than allowing platform-specifc code to define either.
means that kernels from now on are not bootable by !BtRiscBSD but only with
!BtNetBSD.
Big initial commit for a new cleaned up and extended bootblock style. This
patch also allows ELF symbol tables to be read when the patches on the
bootloader are commit but will work fine with the older bootloader.
An extra option `oldkernel' will be provided in the newer bootloader to
pass out old style bootconfig's thus enabling old style kernels to load and
function.
Tested on a.out and ELF (preliminary) kernels with both older and new style
bootconfig blocks.
* 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.
