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.
Semiconductor Au1x00 series on-chip UARTs. Will be merged with
the original com.c driver once a few issues are tidied up. Main
differences from a standard 16550 UART are:
- separate rxdata and txdata registers
- single 16-bit register for the clock divisor
- "enable uart" register
devices. Currently the serial ports and ethernet MAC have working
drivers, and this has only been physically tested on the Au1000 CPU,
but these devices should work on the Au1100 and Au1500 CPUs too.
processor ID field to donote the CPU core revision and the company
options field do donate the SOC chip type, so we need to add an extra
field to the "pridtab" structure to identify these CPUs.
- accumulating all emulation code (including floating-point) in one place
- steal MachFPInterrupt() back from SOFTFLOAT for use only with interrupts
and traps from *real* FPUs
- introducing MachEmulateInst() as a common dispatch point for all
emulated instructions
- cleaning up emulation dispatch in trap()
Also, while we're here, implement MIPS2 LL/SC/SYNC emulation for MIPS1.
Tested on r3k with and without SOFTFLOAT enabled.
* struct sigacts gets a new sigact_sigdesc structure, which has the
sigaction and the trampoline/version. Version 0 means "legacy kernel
provided trampoline". Other versions are coordinated with machine-
dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions. Instead,
sendsig() looks up the handler by peeking in the sigacts for the
process getting the signal (since it has to look in there for the
trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
its arguments based on the trampoline version in the sigacts.
Changes to libc to use the new facility will be checked in later. Kernel
version not bumped; we will ride the 1.6C bump made recently.
performing the accesses, regardless of the size of the data type
requested. Useful for chips which require fixed-width accesses to all
registers.
Cast arguments printed using %lx to u_long all the time, not just
sometimes.
Include a few extra files here so they don't need to be included by the
files that include this one.
and rename TLB_SHUTDOWN and SOFT_RESET to TS and SR (the abbreviations
in the MIPS documentation).
XXX: this file really needs to be cleaned up one day...
