| * MIPS: Malta: CPS SMP by defaultPaul Burton2014-05-282-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The CONFIG_MIPS_CPS SMP implementation should be able to handle all cases the CONFIG_MIPS_CMP implementation does, but without requiring bootloader assistance. It is also required in order to make use of features such as hotplug & cpuidle core power gating. Enable it by default for Malta configs that previously enabled the now deprecated CONFIG_MIPS_CMP, and disable the latter. The local version suffix "cmp" is removed rather than replaced with "cps" since there are other ways to tell that the CPS SMP implementation is in use (the "VPE topology" line in the boot log being one).

| * cpuidle: cpuidle-cps: add MIPS CPS cpuidle driverPaul Burton2014-05-285-0/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a cpuidle driver for systems based around the MIPS Coherent Processing System (CPS) architecture. It supports four idle states: - The standard MIPS wait instruction. - The non-coherent wait, clock gated & power gated states exposed by the recently added pm-cps layer. The pm-cps layer is used to enter all the deep idle states. Since cores in the clock or power gated states cannot service interrupts, the gic_send_ipi_single function is modified to send a power up command for the appropriate core to the CPC in cases where the target CPU has marked itself potentially incoherent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for offlining CPUs via hotplug when using the CONFIG_MIPS_CPS SMP implementation. When a CPU is offlined one of 2 things will happen: - If the CPU is part of a core which implements the MT ASE and there is at least one other VPE online within that core then the VPE will be halted by settings its TCHalt bit. - Otherwise if supported the core will be powered down via the CPC. - Otherwise the CPU will hang by executing an infinite loop. Bringing CPUs back online is then a process of either clearing the appropriate VPEs TCHalt bit or powering up the appropriate core via the CPC. Throughout the process the struct core_boot_config vpe_mask field must be maintained such that mips_cps_boot_vpes will start & stop the correct VPEs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds code to generate entry & exit code for various low power states available on systems based around the MIPS Coherent Processing System architecture (ie. those with a Coherence Manager, Global Interrupt Controller & for >=CM2 a Cluster Power Controller). States supported are: - Non-coherent wait. This state first leaves the coherent domain and then executes a regular MIPS wait instruction. Power savings are found from the elimination of coherency interventions between the core and any other coherent requestors in the system. - Clock gated. This state leaves the coherent domain and then gates the clock input to the core. This removes all dynamic power from the core but leaves the core at the mercy of another to restart its clock. Register state is preserved, but the core can not service interrupts whilst its clock is gated. - Power gated. This deepest state removes all power input to the core. All register state is lost and the core will restart execution from its BEV when another core powers it back up. Because register state is lost this state requires cooperation with the CONFIG_MIPS_CPS SMP implementation in order for the core to exit the state successfully. The code will detect which states are available on the current system during boot & generate the entry/exit code for those states. This will be used by cpuidle & hotplug implementations.

| * MIPS: smp-cps: use CPC core-other lockingPaul Burton2014-05-281-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The core which the CPC core-other region relates to is based upon the core-local core-other addressing register. As its name suggests this register is shared between all VPEs within a core, and if there is a possibility that multiple VPEs within a core will attempt to access another core simultaneously then locking is required. This wasn't previously a problem with the only user being cpu0 during boot, but will be an issue once hotplug is implemented & may race with other users such as cpuidle.

| | | | | | | | | | | | | | | | | | | | | | | | | | The start of mips_cps_core_entry is patched in order to provide the code with the address of the CM register region at a point where it will be running non-coherent with the rest of the system. However the cache wasn't being flushed after that patching which could in principle lead to secondary cores using an invalid CM base address. The patching is moved to cps_prepare_cpus since local_flush_icache_range has not been initialised at the point cps_smp_setup is called. Signed-off-by: Paul Burton <paul.burton@imgtec.com>

| | | | | | | | | | | | | | | | | | The core power down state for cpuidle will require that the CPS SMP implementation is in use. This patch provides a mips_cps_smp_in_use function which determines whether or not the CPS SMP implementation is currently in use. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
| * MIPS: smp-cps: rework core/VPE initialisationPaul Burton2014-05-285-161/+374
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hotplug and/or a powered down idle state are supported cases will arise where a non-zero VPE must be brought online without VPE 0, and it where multiple VPEs must be onlined simultaneously. This patch prepares for that by: - Splitting struct boot_config into core & VPE boot config structures, allocated one per core or VPE respectively. This allows for multiple VPEs to be onlined simultaneously without clobbering each others configuration. - Indicating which VPEs should be online within a core at any given time using a bitmap. This allows multiple VPEs to be brought online simultaneously and also indicates to VPE 0 whether it should halt after starting any non-zero VPEs that should be online within the core. For example if all VPEs within a core are offlined via hotplug and the user onlines the second VPE within that core: 1) The core will be powered up. 2) VPE 0 will run from the BEV (ie. mips_cps_core_entry) to initialise the core. 3) VPE 0 will start VPE 1 because its bit is set in the cores bitmap. 4) VPE 0 will halt itself because its bit is clear in the cores bitmap. - Moving the core & VPE initialisation to assembly code which does not make any use of the stack. This is because if a non-zero VPE is to be brought online in a powered down core then when VPE 0 of that core runs it may not have a valid stack, and even if it did then it's messy to run through parts of generic kernel code on VPE 0 before starting the correct VPE.
