git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/linux-2.6-kgdb
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/linux-2.6-kgdb:
kgdb,ppc: Individual register get/set for ppc
kgdbts: prevent re-entry to kgdbts before it unregisters
debug_core,x86,blackfin: Clean up hw debug disable API
kdb: Fix early debugging crash regression
kgdb,arm: fix register dump
kdb: fix per_cpu command to remove supress mask
kdb: Add kdb kernel module sample
|
|
The kgdb_disable_hw_debug() was an architecture specific function for
disabling all hardware breakpoints on a per cpu basis when entering
the debug core.
This patch will remove the weak function kdbg_disable_hw_debug() and
change it into a call back which lives with the rest of hw breakpoint
call backs in struct kgdb_arch.

Long ago, PT_TRACESYS_OFF and friends were introduced as hard defines to
avoid straight constants in assembler parts of linux m68k. They are not
used anymore, and were not updated to follow changes in linux kernel.
Remove them. When similar constants are needed, they are now generated
using asm-offsets.c.

If the kernel's init section is merged back into the main memory region
during boot (which it should since that is how we've laid out the kernel
linker map), we want to make sure that these aren't counted as independent
regions. Otherwise, if a large mapping is attempted which starts in the
init region and extends into the main memory region, the access_ok func
will deny it. This leads to weird messages during runtime like "unable
to map xxx library" from the ldso but upon running the application again,
everything works fine.
So if the address of the end of the init region is the same as the start
of the main memory region, simply enlarge the memory region to include
the init region.

Many Blackfin parts group sets of pins into a single functional unit.
This means you cannot use different pins within a group for different
peripherals. Our resource conflict checking thus far has been limited
to individual pins, so if someone tried to grab a different pin from
the same group, it would be allowed while silently changing the other
pins in the same group.
One common example is the pin set PG12 - PG15 on BF51x parts. They
may either be used with SPI0 (1st function), or they may be used with
PTP/PWM/AMS3 (3rd function). Ideally, we'd like to use PG12 - PG14
for SPI0 while using PG15 with AMS3, but the hardware does not permit
this. In the past, the software would allow the pins to be requested
this way, but ultimately things like the Blackfin SPI driver would
stop working when the hardware rerouted to a different peripheral.

Flushing caches sometimes requires anomaly workarounds which require
supervisor-only insns. Normally we don't need to flush caches from
userspace so this isn't a problem, but when gcc generates trampolines
on the stack, we do.
So add a new syscall for gcc to use modeled after the mips version.

The num_chipselect field for on-chip Blackfin SPI buses is supposed to

Some peripherals might generate an error interrupt shortly after the
data interrupt due to the fact that the peripheral isn't serviced fast
enough. In most cases this isn't a problem and is expected behavior.
This hasn't been a problem on most parts since you simply don't request
the error interrupt (or you leave it disabled while there is an expected
state) and do the peripheral status checking in the data interrupt.
The Blackfin SIC allows people to prioritize data and error interrupts,
and the Blackfin CEC allows interrupts of equal or higher priority to
nest. The current default settings gives error interrupts a higher
priority than data interrupts. So if an error occurs while processing
the data interrupt, it will be serviced immediately.
However, the error interrupt on the BF537 SIC cannot be enabled on a
per-peripheral basis. Once the error interrupt is enabled for one
peripheral, it is automatically enabled for all peripherals.
Therefore lower the default multiplexed error interrupt priority so
most people need not worry themselves with this issue.
