2008-01-26ARM kprobes: special hook for the kprobes breakpoint handlerNicolas Pitre

Signed-off-by: Nicolas Pitre <nico@marvell.com>
2008-01-26ARM kprobes: core codeAbhishek Sagar
This is a full implementation of Kprobes including Jprobes and Kretprobes support. This ARM implementation does not follow the usual kprobes double- exception model. The traditional model is where the initial kprobes breakpoint calls kprobe_handler(), which returns from exception to execute the instruction in its original context, then immediately re-enters after a second breakpoint (or single-stepping exception) into post_kprobe_handler(), each time the probe is hit.. The ARM implementation only executes one kprobes exception per hit, so no post_kprobe_handler() phase. All side-effects from the kprobe'd instruction are resolved before returning from the initial exception. As a result, all instructions are _always_ effectively boosted regardless of the type of instruction, and even regardless of whether or not there is a post-handler for the probe.

2008-01-26ARM kprobes: instruction single-stepping supportQuentin Barnes
This is the code implementing instruction single-stepping for kprobes on ARM. To get around the limitation of no Next-PC and no hardware single- stepping, all kprobe'd instructions are split into three camps: simulation, emulation, and rejected. "Simulated" instructions are those instructions which behavior is reproduced by straight C code. "Emulated" instructions are ones that are copied, slightly altered and executed directly in the instruction slot to reproduce their behavior. "Rejected" instructions are ones that could be simulated, but work hasn't been put into simulating them. These instructions should be very rare, if not unencountered, in the kernel. If ever needed, code could be added to simulate them. One might wonder why this and the ptrace singlestep facility are not sharing some code. Both approaches are fundamentally different because the ptrace code regains control after the stepped instruction by installing a breakpoint after the instruction itself, and possibly at the location where the instruction might be branching to, instead of simulating or emulating the target instruction. The ptrace approach isn't suitable for kprobes because the breakpoints would have to be moved back, and the icache flushed, everytime the probe is hit to let normal code execution resume, which would have a significant performance impact. It is also racy on SMP since another CPU could, with the right timing, sail through the probe point without being caught. Because ptrace single-stepping always result in a different process to be scheduled, the concern for performance is much less significant. On the other hand, the kprobes approach isn't (currently) suitable for ptrace because it has no provision for proper user space memory protection and translation, and even if that was implemented, the gain wouldn't be worth the added complexity in the ptrace path compared to the current approach. So, until kprobes does support user space, both kprobes and ptrace are best kept independent and separate.

2008-01-26[ARM] Orion: provide GPIO method for enabling hardware assisted blinkingHerbert Valerio Riedel
This is a pre-requisite for implementing proper hardware accelerated GPIO LED flashing, and since we want proper locking, it's sensible to provide the orion specific orion_gpio_set_blink() implementation within mach-orion/gpio.c.

This patch allows the VFP support code to run correctly on CPUs compatible with the common VFP subarchitecture specification (Appendix B in the ARM ARM v7-A and v7-R edition). It implements support for VFP subarchitecture 2 while being backwards compatible with subarchitecture 1. On VFP subarchitecture 1, the arithmetic exceptions are asynchronous (or imprecise as described in the old ARM ARM) unless the FPSCR.IXE bit is 1. The exceptional instructions can be read from FPINST and FPINST2 registers. With VFP subarchitecture 2, the arithmetic exceptions can also be synchronous and marked by the FPEXC.DEX bit (the FPEXC.EX bit is cleared). CPUs implementing the synchronous arithmetic exceptions don't have the FPINST and FPINST2 registers and accessing them would trigger and undefined exception. Note that FPEXC.EX bit has an additional meaning on subarchitecture 1 - if it isn't set, there is no additional information in FPINST and FPINST2 that needs to be saved at context switch or when lazy-loading the VFP state of a different thread. The patch also removes the clearing of the cumulative exception flags in FPSCR when additional exceptions were raised. It is up to the user application to clear these bits.

2008-01-26[ARM] 4671/1: ep93xx: remove obsolete gpio_line_* operationsHerbert Valerio Riedel
With the new GPIO methods in place the old gpio_line_* methods are redundant, so this patch finally removes the old legacy gpio_line_* wrappers.

2008-01-26[ARM] 4669/1: ep93xx: simplify GPIO code and cleanupsHerbert Valerio Riedel
This patch renumbers the (virtual) GPIO line numbering to have all irq-capable gpio lines <= EP93XX_GPIO_LINE_MAX_IRQ by swapping the port f range with the port c range; This simplifies code such as #define IRQ_EP93XX_GPIO(x) (64 + (((x) + (((x) >> 2) & 8)) & 0x1f)) or if (line >= 0 && line < 16) { /* Port A/B */ } else if (line >= 40 && line < 48) { /* Port F */ } considerably; in addition to the renumbering this patch also introduces macro constants EP93XX_GPIO_LINE_MAX_IRQ and EP93XX_GPIO_LINE_MAX, and replaces most magic numbers by those and invocations of gpio_to_irq()/irq_to_gpio().
