2015-12-22nvdimm acpi: build ACPI NFIT tableXiao Guangrong
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT) Currently, we only support PMEM mode. Each device has 3 structures: - SPA structure, defines the PMEM region info - MEM DEV structure, it has the @handle which is used to associate specified ACPI NVDIMM device we will introduce in later patch. Also we can happily ignored the memory device's interleave, the real nvdimm hardware access is hidden behind host - DCR structure, it defines vendor ID used to associate specified vendor nvdimm driver. Since we only implement PMEM mode this time, Command window and Data window are not needed The NVDIMM functionality is controlled by the parameter, 'nvdimm', which is introduced for the machine, there is a example to enable it: -machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \ memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \ nvdimm,memdev=mem1,id=nv1 It is disabled on default Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

2015-12-22sdhci: add optional quirk property to disable card insertion/removal interruptsAndrew Baumann
This is needed for a quirk of the Raspberry Pi (bcm2835/6) MMC controller, where the card insert bit is documented as unimplemented (always reads zero, doesn't generate interrupts) but is in fact observed on hardware as set at power on, but is cleared (and remains clear) on subsequent controller resets.

This deletes a block of code that raised a command index error if a command returned response data, but the guest did not set the appropriate bits in the response register to handle such a response. I cannot find any documentation that suggests the controller should behave in this way, the error code doesn't make sense (command index error is defined for the case where the index in a response does not match that of the issued command), and in at least one case (CMD23 issued by UEFI on Raspberry Pi 2), actual hardware does not do this.

2015-12-22sd: sdhci: Delete over-zealous power checkPeter Crosthwaite
This check was conditionalising SD card operation on the card being powered by the SDHCI host controller. It is however possible (particularly in embedded systems) for the power control of the SD card to be managed outside of SDHCI. This can be as trivial as hard-wiring the SD slot VCC to a constant power-rail. This means the guest SDHCI can validly opt-out of the SDHCI power control feature while still using the card. So delete this check to allow operation of the card with SDHCI power control. This is needed for at least Xilinx Zynq and Raspberry Pi, and also makes Freescale i.MX25 work for me. The digilent Zybo board has a public schematic which shows SD VCC hardwiring: http://digilentinc.com/Data/Products/ZYBO/ZYBO_sch_VB.3.pdf bottom of page 3.

2015-12-17kvm: x86: add support for KVM_CAP_SPLIT_IRQCHIPPaolo Bonzini
This patch adds support for split IRQ chip mode. When KVM_CAP_SPLIT_IRQCHIP is enabled: 1.) The PIC, PIT, and IOAPIC are implemented in userspace while the LAPIC is implemented by KVM. 2.) The software IOAPIC delivers interrupts to the KVM LAPIC via kvm_set_irq. Interrupt delivery is configured via the MSI routing table, for which routes are reserved in target-i386/kvm.c then configured in hw/intc/ioapic.c 3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI, which is handled in target-i386/kvm.c and relayed to the software IOAPIC via ioapic_eoi_broadcast.
