2014-07-11misc: mic: add a bus driver for virtual MIC devicesSudeep Dutt5-0/+351
This MIC virtual bus driver takes the responsibility of creating all the virtual devices connected to the PCIe device on the host and the platform device on the card. The MIC bus hardware operations provide a way to abstract certain hardware details from the base physical devices. Examples of devices added on the MIC virtual bus include host DMA and card DMA. This abstraction enables using a common DMA driver on host and card.

2014-07-11tools: selftests - create a separate hotplug target for full range testShuah Khan6-6/+105
On some systems, hot-plug tests could hang forever waiting for cpu and memory to be ready to be offlined. A special hot-plug target is created to run full range of hot-plug tests. In default mode, hot-plug tests run in safe mode with a limited scope. In limited mode, cpu-hotplug test is run on a single cpu as opposed to all hotplug capable cpus, and memory hotplug test is run on 2% of hotplug capable memory instead of 10%. In addition to the above change, cpu-hotplug is chnged to change processor affinity to cpu 0 so it doesn't impact itself while the test runs.

2014-07-09ipoctal: request_irq after configurationFederico Vaga1-7/+8

Sometimes, it happens that something is not completely configured, we recieve an interrupt thus we stumble into troubles in the IRQ handler.

2014-07-09ipoctal: protect only the real critical sectionFederico Vaga1-3/+2
In some conditions (echo or particular sequence of special characters), on buffer push, the tty layer calls the write operation while we are holding the spinlock. This means deadlock within the same process on kernels version < 3.12. It seems not a problem on recent kernel, but the patch still valid as locking optimization. The protected variables by the spinlock are: xmit_buf, nb_bytes, pointer_read and pointer_write. So, this patch reduces the locked area in the IRQ handler only to these variables. Most of the code inside the locked area in the IRQ handler is not protected elsewhere; it means that it is not protected at all.

2014-07-09pcmcia: pxa2xx: fix logic for lubbockArnd Bergmann1-1/+1
The lubbock platform uses the sa1111 companion chip with a pxa250 CPU, which means it requires both the PCMCIA_SA1111 and the PCMCIA_PXA2XX code to be built into the kernel. Unfortunately, the Makefile and Kconfig don't agree on how this is accomplished, leading to a situation where you get this link error when building a lubbock kernel with PCMCIA_SA1111 enabled but PCMCIA_PXA2XX disabled: ERROR: "pxa2xx_configure_sockets" [drivers/pcmcia/sa1111_cs.ko] undefined! ERROR: "pxa2xx_drv_pcmcia_ops" [drivers/pcmcia/sa1111_cs.ko] undefined! ERROR: "pxa2xx_drv_pcmcia_add_one" [drivers/pcmcia/sa1111_cs.ko] undefined!

2014-07-09misc/GenWQE: fix pci_enable_msi usageSebastian Ott2-7/+7
GenWQE used to call pci_enable_msi_block to allocate a desired number of MSI's. If that was not possible pci_enable_msi_block returned with a smaller number which might be possible to allocate. GenWQE then called pci_enable_msi_block with that number. Since commit a30d0108b "GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()" pci_enable_msi_exact is used which fails if the desired number of MSI's was not possible to allocate.

2014-07-09GenWQE: Improve hardware error recoveryKleber Sacilotto de Souza1-0/+45
Currently, in the event of a fatal hardware error, the driver tries a recovery procedure that calls pci_reset_function() to reset the card. This is not sufficient in some cases, needing a fundamental reset to bring the card back. This patch implements a call to the platform fundamental reset procedure on the error recovery path if GENWQE_PLATFORM_ERROR_RECOVERY is enabled. This is implemented by default only on PPC64, since this can cause problems on other archs, e.g. zSeries, where the platform has its own recovery procedures, leading to a potencial race conditition. For these cases, the recovery is kept as it was before.

2014-07-09GenWQE: Add support for EEH error recoveryKleber Sacilotto de Souza7-18/+115
This patch implements the callbacks and functions necessary to have EEH recovery support. It adds a config option to enable or disable explicit calls to trigger platform specific mechanisms on error recovery paths. This option is enabled by default only on PPC64 systems and can be overritten via debugfs. If this option is enabled, on the error recovery path the driver will call pci_channel_offline() to check for error condition and issue non-raw MMIO reads to trigger early EEH detection in case of hardware failures. This is necessary since the driver MMIO helper funtions use raw accessors.
