2015-06-09Documentation: ARM: EXYNOS: Describe boot loaders interfaceKrzysztof Kozlowski1-0/+53
Various boot loaders for Exynos based boards use certain memory addresses during booting for different purposes. Mostly this is one of following : 1. as a CPU boot address, 2. for storing magic cookie related to low power mode (AFTR, sleep). The document, based solely on kernel source code, tries to group the information scattered over different files. This would help in the future when adding support for new SoC or when extending features related to low power modes.

Since 688d4dfcdd624192cbf03c08402e444d1d11f294 "perf tools: Support parsing parameterized events" the perf userspace tools understands "argument=?" syntax in the events file, making sure that required arguments are provided by the user and not defaulting to 0, causing confusion. This patch adds the required arguments lists for CCN events. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
2015-05-01bus: arm-ccn: cpumask attributePawel Moll1-6/+9
This patch adds a "cpumask" attribute to CCN's event_source class sysfs directory. Perf user tool uses it to restrict events to the processor(s) enumerated in this mask. This patch provides a single CPU mask, making it possible to run "-a" perf session (previously it would request the same CCN event, for example cycle counter, on each available core and most likely fail). Initially the mask is set to the CPU that happened to probe the driver, but it will be changed when it is hot-un-plugged (active events are migrated to another CPU then). Example: Performance counter stats for 'system wide': CPU0 2968148 cycles CPU1 2236736 cycles CPU2 1797968 cycles CPU3 1831715 cycles CPU1 1201850868 ccn/cycles/ 1.001241383 seconds time elapsed Signed-off-by: Pawel Moll <pawel.moll@arm.com>

2014-10-20ARM: firmware: Introduce suspend and resume operationsTomasz Figa1-23/+5
This patch extends the firmware_ops structure with two new callbacks: .suspend() and .resume(). The former is intended to ask the firmware to save all its volatile state and suspend the system, without returning back to the kernel in between. The latter is to be called early by very low level platform suspend code after waking up to restore low level hardware state, which can't be restored in non-secure mode. While at it, outdated version of the structure is removed from the documentation and replaced with a reference to the header file.

2014-10-17ARM: expand fixmap region to 3MBRob Herring1-1/+1
With commit a05e54c103b0 ("ARM: 8031/2: change fixmap mapping region to support 32 CPUs"), the fixmap region was expanded to 2MB, but it precluded any other uses of the fixmap region. In order to support other uses the fixmap region needs to be expanded beyond 2MB. Fortunately, the adjacent 1MB range 0xffe00000-0xfff00000 is availabe. Remove fixmap_page_table ptr and lookup the page table via the virtual address so that the fixmap region can span more that one pmd. The 2nd pmd is already created since it is shared with the vector page.

Pull ARM updates from Russell King: - Major clean-up of the L2 cache support code. The existing mess was becoming rather unmaintainable through all the additions that others have done over time. This turns it into a much nicer structure, and implements a few performance improvements as well. - Clean up some of the CP15 control register tweaks for alignment support, moving some code and data into alignment.c - DMA properties for ARM, from Santosh and reviewed by DT people. This adds DT properties to specify bus translations we can't discover automatically, and to indicate whether devices are coherent. - Hibernation support for ARM - Make ftrace work with read-only text in modules - add suspend support for PJ4B CPUs - rework interrupt masking for undefined instruction handling, which allows us to enable interrupts earlier in the handling of these exceptions. - support for big endian page tables - fix stacktrace support to exclude stacktrace functions from the trace, and add save_stack_trace_regs() implementation so that kprobes can record stack traces. - Add support for the Cortex-A17 CPU. - Remove last vestiges of ARM710 support. - Removal of ARM "meminfo" structure, finally converting us solely to memblock to handle the early memory initialisation. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits) ARM: ensure C page table setup code follows assembly code (part II) ARM: ensure C page table setup code follows assembly code ARM: consolidate last remaining open-coded alignment trap enable ARM: remove global cr_no_alignment ARM: remove CPU_CP15 conditional from alignment.c ARM: remove unused adjust_cr() function ARM: move "noalign" command line option to alignment.c ARM: provide common method to clear bits in CPU control register ARM: 8025/1: Get rid of meminfo ARM: 8060/1: mm: allow sub-architectures to override PCI I/O memory type ARM: 8066/1: correction for ARM patch 8031/2 ARM: 8049/1: ftrace/add save_stack_trace_regs() implementation ARM: 8065/1: remove last use of CONFIG_CPU_ARM710 ARM: 8062/1: Modify ldrt fixup handler to re-execute the userspace instruction ARM: 8047/1: rwsem: use asm-generic rwsem implementation ARM: l2c: trial at enabling some Cortex-A9 optimisations ARM: l2c: add warnings for stuff modifying aux_ctrl register values ARM: l2c: print a warning with L2C-310 caches if the cache size is modified ARM: l2c: remove old .set_debug method ARM: l2c: kill L2X0_AUX_CTRL_MASK before anyone else makes use of this ...
