| * ARM: 7445/1: mm: update CONTEXTIDR register to contain PID of current processWill Deacon2012-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a new Kconfig option which, when enabled, causes the kernel to write the PID of the current task into the PROCID field of the CONTEXTIDR on context switch. This is useful when analysing hardware trace, since writes to this register can be configured to emit an event into the trace stream. The thread notifier for writing the PID is deliberately kept separate from the ASID-writing code so that we can support newer processors using LPAE, where the ASID is stored in TTBR0. As such, the switch_mm code is updated to perform a read-modify-write sequence to ensure that we don't clobber the PID on CPUs using the classic 2-level page tables.

* | ARM: vexpress: Config option for early printk consolePawel Moll2012-07-13
|/ | | | | | | | | | | | | | | | Versatile Express platform can be used in different configurations, the console UART used by early printk may be located at different addresses in the address space. This patch makes it possible to select the base address of a PL011 UART to be used as a console output in the kernel configuration. The default behaviour is still the heuristic detecting memory map on Cortex-A core tiles. The zImage decompressor will use the same configuration values or print out nothing if DEBUG_LL is not enabled. Signed-off-by: Pawel Moll <pawel.moll@arm.com>

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enabling CONFIG_DEBUG_LL (which is required for earlyprintk) hardwires the debug UART address into the kernel, so that we can print before the platform is initialised. If the user inadvertently selects multiple platforms with DEBUG_LL enabled, the UART address may not be correct and will likely cause the kernel to hang in the very early stages of boot. This patch, based on a skeleton from Russell, uses a Kconfig choice for selecting the DEBUG_LL UART, therefore allowing the user to make a choice about the supported platform when DEBUG_LL is enabled.

| * ARM: Ensure experimental options are so markedRussell King2010-12-05
| | | | | | | | | | | | | | | | | | | | It is kernel-wide policy that options depending on EXPERIMENTAL should also have '(EXPERIMENTAL)' in their option text, and options with '(EXPERIMENTAL)' depend on EXPERIMENTAL. Ensure that all ARM options comply with this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | ARM: ftrace: enable function graph tracerRabin Vincent2010-11-19
|/ | | | | | | | | | | | | Add the options to enable the function graph tracer on ARM. Function graph tracer support requires frame pointers, so exclude Thumb-2 and also make sure FRAME_POINTER gets enabled when FUNCTION_GRAPH_TRACER is used, since FUNCTION_TRACER doesn't "select FRAME_POINTER" when ARM_UNWIND is used. Therefore, with GCC 4.4.0+, you get plain function tracing without frame pointers, but you'll need them if you want function graph tracing.

| * ARM: implement CONFIG_STRICT_DEVMEM by disabling access to RAM via /dev/memNicolas Pitre2010-10-01
| | | | | | | | | | | | | | | | There are very few legitimate use cases, if any, for directly accessing system RAM through /dev/mem. So let's mimic what they do on x86 and forbid it when CONFIG_STRICT_DEVMEM is turned on. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

This is essential for Thumb-2 support, since frame pointers aren't available then.

| | | | | | | | | | | Move the Kconfig entries from plat-s3c to plat-samsung and plat-s3c24xx as necessary. The S3C_BOOT entries and the DMA configuration can go to plat-samsung. The low-level UART configurations are currently S3C2XX specific and can go to plat-s3c24xx. Eliminating plat-s3c from the build process will be submitted seperately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver implements support for on-chip Embedded Tracing Macrocell and Embedded Trace Buffer. It allows to trigger tracing of kernel execution flow and exporting trace output to userspace via character device and a sysrq combo. Trace output can then be decoded by a fairly simple open source tool [1] which is already sufficient to get the idea of what the kernel is doing.
