The big.LITTLE architecture is composed of two clusters of cpus. One cluster contains less powerful but more energy efficient processors and the other cluster groups the powerful but energy-intensive cpus. The TC2 testchip implements two clusters of CPUs (A7 and A15 clusters in a big.LITTLE configuration) connected through a CCI interconnect that manages coherency of their respective L2 caches and intercluster distributed virtual memory messages (DVM). TC2 testchip integrates a power controller that manages cores resets, wake-up IRQs and cluster low-power states. Power states are managed at cluster level, which means that voltage is removed from a cluster iff all cores in a cluster are in a wfi state. Single cores can enter a reset state which is identical to wfi in terms of power consumption but simplifies the way cluster states are entered. This patch provides a multiple driver CPU idle implementation for TC2 which paves the way for a generic big.LITTLE idle driver for all upcoming big.LITTLE based systems on chip. The driver relies on the MCPM infrastructure to coordinate and manage core power states; in particular MCPM allows to suspend specific cores and hides the CPUs coordination required to shut-down clusters of CPUs. Power down sequences for the respective clusters are implemented in the MCPM TC2 backend, with all code needed to clean caches and exit coherency. The multiple driver CPU idle infrastructure allows to define different C-states for big and little cores, determined at boot by checking the part id of the possible CPUs and initializing the respective logical masks in the big and little drivers. Current big.little systems are composed of A7 and A15 clusters, as implemented in TC2, but in the future that may change and the driver will have evolve to retrieve what is a 'big' cpu and what is a 'little' cpu in order to build the correct topology.

由 Nicolas Pitre 提交于
When processors are about to hit low power states, the assertion of standbywfi signal, triggered by the wfi instruction, is essential to entering low power modes. If an IRQ is pending on the processor at the time wfi is issued, the wfi instruction completes and the processor restarts execution without asserting the standbywfi signal. Depending on the platform power controller HW this behaviour can be acceptable or not; if this behaviour must be prevented software should be provided with a way to disable the routing of interrupts to the core IRQ pins. On systems where raw GIC distributor interrupts are connected to the power controller as wake-up events (hence the power controller still senses IRQs and can wake up cores upon IRQ pending), the GIC CPU interface can be disabled on power down, so that the GIC CPU IF output is gated and wfi cannot complete, thereby preventing the standbywfi issue. This patch adds a simple function to the GIC driver that allows to disable the GIC CPU IF from power down procedures.

In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

Fix a BUG which can trigger when direct-IO is used with AOE. As discussed previously, the fact that some users of the block layer provide bios that point to pages with a zero _count means that it is not OK for the network layer to do a put_page on the skb frags during an skb_linearize, so the aoe driver gets a reference to pages in bios and puts the reference before ending the bio. And because it cannot use get_page on a page with a zero _count, it manipulates the value directly. It is not OK to increment the _count of a compound page tail, though, since the VM layer will VM_BUG_ON a non-zero _count. Block users that do direct I/O can result in the aoe driver seeing compound page tails in bios. In that case, the same logic works as long as the head of the compound page is used instead of the tails. This patch handles compound pages and does not BUG. It relies on the block layer user leaving the relationship between the page tail and its head alone for the duration between the submission of the bio and its completion, whether successful or not.

Some platforms (e.g S390) don't use the generic hardirqs code and therefore do not defined HAVE_GENERIC_HARDIRQS. This prevents using the irq_set_chip_data() and irq_get_chip_data() functions that are used for the default implementations of the MSI operations. So, when CONFIG_GENERIC_HARDIRQS is not enabled, provide another default implementation of the MSI operations, that simply errors out. The architecture is responsible for implementing those operations (which is the case on S390), and cannot use the msi_chip infrastructure.

This patch fixes a kernel panic that can occur when disconnecting a wireless USB->serial device. When the serial device disconnects, the device cleanup procedure ends up calling usb_hcd_disable_endpoint on the serial device's endpoints. The wusbcore uses the ABORT_RPIPE command to abort all transfers on the given endpoint but it does not properly give back the URBs when the transfer results return from the HWA. This patch prevents the transfer result processing code from bailing out when it sees a WA_XFER_STATUS_ABORTED result code so that these urbs are flushed properly by usb_hcd_disable_endpoint. It also updates wa_urb_dequeue to handle the case where the endpoint has already been cleaned up when usb_kill_urb is called which is where the panic originally occurred.

Since commits 4005ad43 (EHCI: implement new semantics for URB_ISO_ASAP) and c75c5ab5 (ALSA: USB: adjust for changed 3.8 USB API) became widely distributed, people have been experiencing problems with audio transfers. The slightest underrun causes complete failure, requiring the audio stream to be restarted. It turns out that the current isochronous API doesn't handle underruns in the best way. The ALSA developers would much rather have transfers that are submitted too late be accepted and complete in the normal fashion, rather than being refused outright. This patch implements the requested approach. When an isochronous URB submission is so late that all its scheduled slots have already expired, a debugging message will be printed in the log and the URB will be accepted as usual. Assuming it was submitted by a completion handler (which is normally the case), it will complete shortly thereafter with all the usb_iso_packet_descriptor status fields marked -EXDEV.

Until now, the MSI architecture-specific functions could be overloaded using a fairly complex set of #define and compile-time conditionals. In order to prepare for the introduction of the msi_chip infrastructure, it is desirable to switch all those functions to use the 'weak' mechanism. This commit converts all the architectures that were overidding those MSI functions to use the new strategy. Note that we keep two separate, non-weak, functions default_teardown_msi_irqs() and default_restore_msi_irqs() for the default behavior of the arch_teardown_msi_irqs() and arch_restore_msi_irqs(), as the default behavior is needed by x86 PCI code.
