* ARM: 6358/1: hw-breakpoint: add HAVE_HW_BREAKPOINT to KconfigWill Deacon2010-09-082-0/+2
| | | | | | | | | | If we're targetting a v6 or v7 core and have at least software perf events available, then automatically add support for hardware breakpoints.

* ARM: 6357/1: hw-breakpoint: add new ptrace requests for hw-breakpoint ↵Will Deacon2010-09-085-1/+261
| | | | | | | | | | | | | | | | | interaction For debuggers to take advantage of the hw-breakpoint framework in the kernel, it is necessary to expose the API calls via a ptrace interface. This patch exposes the hardware breakpoints framework as a collection of virtual registers, accesible using PTRACE_SETHBPREGS and PTRACE_GETHBPREGS requests. The breakpoints are stored in the debug_info struct of the running thread. Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: S.

* ARM: 6356/1: hw-breakpoint: add ARM backend for the hw-breakpoint frameworkWill Deacon2010-09-082-0/+972
| | | | | | | | | | | | | | | | | | | | | | | | The hw-breakpoint framework in the kernel requires architecture-specific support in order to install, remove, validate and manage hardware breakpoints. This patch adds initial support for this framework to the ARM architecture, but restricts the number of watchpoints to a single resource to get around the fact that the Data Fault Address Register is unknown when a watchpoint debug exception is taken. On cores with v7 debug, the Kernel can handle breakpoint and watchpoint exceptions occuring from userspace. Older cores require clients to handle the exception themselves by registering an appropriate overflow handler or, in the case of ptrace, handling the raised SIGTRAP. The memory-mapped extended debug interface is unsupported due to its unreliability in real implementations. Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: S.

* ARM: 6355/1: hw-breakpoint: add mechanism for hooking into prefetch abortsWill Deacon2010-09-082-0/+17
| | | | | | | | | | | | | | | On ARM processors with hardware breakpoint and watchpoint support, triggering these events results in a debug exception. These manifest as prefetch and data aborts respectively. arch/arm/mm/fault.c already provides hook_fault_code for hooking into data aborts dependent on the DFSR. This patch adds a new function, hook_ifault_code for hooking into prefetch aborts in the same manner. Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: S.

This occurs because we make kmalloc calls, which can block, while parsing the rtas_data_buf and holding the rtas_data_buf_lock. This an cause issues if someone else attempts to grab the rtas_data_bug_lock. This patch alleviates this issue by copying the contents of the rtas_data_buf to a local buffer before parsing. This allows us to only hold the rtas_data_buf_lock around the RTAS configure-connector calls.

Unfortunately, this stack pointer can't be used when translation is off on PHYP as this stack pointer might be outside the RMO. This results in the following on all non zero cpus: cpu 0x1: Vector: 300 (Data Access) at [c00000001639fd10] pc: 000000000001c50c lr: 000000000000821c sp: c00000001639ff90 msr: 8000000000001000 dar: c00000001639ffa0 dsisr: 42000000 current = 0xc000000016393540 paca = 0xc000000006e00200 pid = 0, comm = swapper The original patch was only tested on bare metal system, so it never caught this problem. This changes __secondary_start so that we calculate the new stack pointer but only start using it after we've called early_setup_secondary. With this patch, the above problem goes away.

Unfortunately this moved it after the code that checks whether it is time for the next decrementer clock event. The result is that the call to perf_event_do_pending() won't happen until the next decrementer clock event is due. This was pointed out by Milton Miller. This fixes it by moving the check for whether it's time for the next decrementer clock event down to the point where we're about to call the event handler, after we've called perf_event_do_pending. This has the side effect that on old pre-Core99 Powermacs where we use the ppc_n_lost_interrupts mechanism to replay interrupts, a replayed interrupt will incur a little more latency since it will now do the code from the irq_enter down to the irq_exit, that it used to skip. However, these machines are now old and rare enough that this doesn't matter. To make it clear that ppc_n_lost_interrupts is only used on Powermacs, and to speed up the code slightly on non-Powermac ppc32 machines, the code that tests ppc_n_lost_interrupts is now conditional on CONFIG_PMAC as well as CONFIG_PPC32.

During idle, if the PER powerdomain transitions into a lower state and CORE does not, the IO pad wakeups are not being disabled in the idle path after they are enabled. This can happen with the lower C-states when using CPUidle for example. This patch ensures that the check for disabling IO wakeups also checks for PER transitions, matching the check done to enable IO wakeups. Found when debugging PM/CPUidle related problems reported by Ameya Palande <ameya.palande@nokia.com>. Problems were triggered particularily on boards with UART2 consoles (n900, Overo) since UART2 is in the PER powerdomain. Tested on l-o master (omap3_defonfig + CONFIG_CPU_IDLE=y) as well as with current PM branch. Boards tested: n900, Overo, omap3evm.

However, CONFIG_SMP won't currently work properly on uniprocessor ARMs, or if support for earlier ARM cores is selected in. Fix this by updating omap_4430sdp_defconfig to not select omap2 or 3 at this point. Signed-off-by: Tony Lindgren <tony@atomide.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
