2010-03-09Blackfin: add support for the on-chip MAC status interruptsMichael Hennerich4-7/+166
This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in phylib. New Interrupts added: IRQ_MAC_PHYINT /* PHY_INT Interrupt */ IRQ_MAC_MMCINT /* MMC Counter Interrupt */ IRQ_MAC_RXFSINT /* RX Frame-Status Interrupt */ IRQ_MAC_TXFSINT /* TX Frame-Status Interrupt */ IRQ_MAC_WAKEDET /* Wake-Up Interrupt */ IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */ IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */ IRQ_MAC_STMDONE /* Station Mgt. Transfer Done Interrupt */ On BF537/6 the implementation is not straight forward since there are now two chained chained_handlers. A cleaner approach would have been to add latter IRQs to the demux of IRQ_GENERIC_ERROR.

2010-03-09Blackfin: check for bad syscalls after tracing itMike Frysinger1-9/+14
We want to report all system calls (even invalid ones) to the tracing layers, so check the NR only after we've notified. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: fix single stepping over system callsMike Frysinger4-3/+15
On Blackfin systems, the hardware single step exception triggers before the system call exception, so we need to save this info to process it later on. Otherwise, single stepping in userspace misses a few insns right after the system call. This is based a bit on the SuperH code added in commit 4b505db9c4c72dbd.

2010-03-09Blackfin: simplify SYSCFG code a bit and ignore attempts to change itMike Frysinger1-18/+6
We don't want to let user space modify the SYSCFG register arbitrarily as the settings are system wide (SNEN/CNEN) and can cause misbehavior. The only other bit here (SSSTEP) has proper controls via PTRACE_SINGLESTEP. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-03-09Blackfin: use generic ptrace_resume codeChristoph Hellwig1-44/+0
Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in <asm/ptrace.h> and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code.

2010-03-09Blackfin: rewrite resync_core_{i,d}cache() SMP logic to avoid per_cpu dataGraf Yang4-6/+13
This functions are implicitly called by core functions like cpu_relax(), and since those functions may be called early on before common code has initialized the per-cpu data area, we need to tweak the stats gathering. Now the statistics are maintained in common bss which makes these funcs safe to use as soon as the C runtime env is setup.

2010-03-09Blackfin: fix up mm locking in address dumpingGraf Yang1-1/+13
The locking code in the address dumper needs to grab the mm's mmap_sem so that other CPUs do not get an inconsistent view. On UP systems this really wasn't a problem, but it is easy to trigger a race on SMP systems when another CPU removes a mapping.
