* | MIPS: Lantiq: add SoC specific code for XWAY familyJohn Crispin2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Lantiq XWAY family of Mips24KEc SoCs. * Danube (PSB50702) * Twinpass (PSB4000) * AR9 (PSB50802) * Amazon SE (PSB5061) The Amazon SE is a lightweight SoC and has no PCI as well as a different clock. We split the code out into seperate files to handle this. The GPIO pins on the SoCs are multi function and there are several bits we can use to configure the pins. To be as compatible as possible to GPIOLIB we add a function int lq_gpio_request(unsigned int pin, unsigned int alt0, unsigned int alt1, unsigned int dir, const char *name); which lets you configure the 2 "alternate function" bits. This way drivers like PCI can make use of GPIOLIB without a cubersome wrapper. The PLL code inside arch/mips/lantiq/xway/clk-xway.c is voodoo to me. It was taken from a 2.4.20 source tree and was never really changed by me since then.

* MIPS, Perf-events: Work with irq_workDeng-Cheng Zhu2011-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the MIPS part of the following commit by Peter Zijlstra: - e360adbe29241a0194e10e20595360dd7b98a2b3 irq_work: Add generic hardirq context callbacks Provide a mechanism that allows running code in IRQ context. It is most useful for NMI code that needs to interact with the rest of the system -- like wakeup a task to drain buffers. Perf currently has such a mechanism, so extract that and provide it as a generic feature, independent of perf so that others may also benefit. The IRQ context callback is generated through self-IPIs where possible, or on architectures like powerpc the decrementer (the built-in timer facility) is set to generate an interrupt immediately. Architectures that don't have anything like this get to do with a callback from the timer tick. These architectures can call irq_work_run() at the tail of any IRQ handlers that might enqueue such work (like the perf IRQ handler) to avoid undue latencies in processing the work. For MIPSXX, we need to call irq_work_run() at the tail of the perf IRQ handler as described above.

This patch segregates the early code so that only those architectures which care about it need compile it.

* MIPS: add support for hardware performance events (skeleton)Deng-Cheng Zhu2010-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides the skeleton of the HW perf event support. To enable this feature, we can not choose the SMTC kernel; Oprofile should be disabled; kernel performance events be selected. Then we can enable it in Kernel type menu. Oprofile for MIPS platforms initializes irq at arch init time. Currently we do not change this logic to allow PMU reservation. If a platform has EIC, we can use the irq base and perf counter irq offset defines for the interrupt controller in specific init_hw_perf_events(). Based on this skeleton patch, the 3 different kinds of MIPS PMU, namely, mipsxx/loongson2/rm9000, can be supported by adding corresponding lower level C files at the bottom. The suggested names of these files are perf_event_mipsxx.c/perf_event_loongson2.c/perf_event_rm9000.c. So, for example, we can do this by adding "#include perf_event_mipsxx.c" at the bottom of perf_event.c. In addition, PMUs with 64bit counters are also considered in this patch.
