2014-12-11powerpc/fsl-soc: Disable CPC sole-data mode if KVM enabledScott Wood
Set undocumented bit to disable CPC sole data mode, making it safe to use the LRAT with KVM guests, which could otherwise hang the host (under certain usage patterns) by accessing memory with the M bit unset. The guest still needs to set the M bit to operate properly, but this removes a DoS vector. Only do so if CONFIG_KVM is enabled as supposedly disabling this affects performance, though I wasn't able to detect a difference in the workloads I ran.

When we send pme turnoff message in pci controller suspend, the links will into l2/l3 ready, then, host cannot communicate with ep device, but pci-driver will call back EP device to save them state. So we need to change platform_driver->suspend/resume to syscore->suspend/resume. So the new suspend/resume implementation, send pme turnoff message in suspend, and send pme exit message in resume. And add a PME handler, to response PME & message interrupt.

This piece of code and related TLBs are prefetched in advance. Due to the different initialization code between 32-bit and 64-bit, they have seperate resume entry and precedure.

2014-03-31powerpc/mpic: supply a .disable callbackChenhui Zhao
Currently MPIC provides .mask, but not .disable. This means that effectively disable_irq() soft-disables the interrupt, and you get a .mask call if an interrupt actually occurs. I'm not sure if this was intended as a performance benefit (it seems common to omit .disable on powerpc interrupt controllers, but nowhere else), but it interacts badly with threaded/workqueue interrupts (including KVM reflection). In such cases, where the real interrupt handler does a disable_irq_nosync(), schedules defered handling, and returns, we get two interrupts for every real interrupt. The second interrupt does nothing but see that IRQ_DISABLED is set, and decide that it would be a good idea to actually call .mask. In the sleep case, disable all irqs of IP blocks using .disable() when entering sleep.

2014-03-17fsl_pci_ep: add MSIX supportMinghuan Lian
1. The patch initializes MSIX trap outbound window, the application can map this window and trigger the MSIX interrupt. 2. The patch initializes MSIX inbound window which is used to store MSIX vector and PBA data. 3. Add sysfs node to display MSIX vector setting for example: # cat /sys/class/pci_ep/pci0-pf0/msix MSIX venctor 0: control:0x0 data:0x0000406c addr:0x00000000fee00000 MSIX venctor 1: control:0x0 data:0x0000407c addr:0x00000000fee00000 MSIX venctor 2: control:0x0 data:0x0000408c addr:0x00000000fee00000 MSIX venctor 3: control:0x0 data:0x0000409c addr:0x00000000fee00000 MSIX venctor 4: control:0x0 data:0x000040ac addr:0x00000000fee00000 MSIX venctor 5: control:0x0 data:0x00000000 addr:0x0000000000000000 MSIX venctor 6: control:0x0 data:0x00000000 addr:0x0000000000000000 MSIX venctor 7: control:0x0 data:0x00000000 addr:0x0000000000000000 Signed-off-by: Minghuan Lian <Minghuan.Lian@freescale.com> Change-Id: I18a6f9056b3c630bba91f5f1dfef2eee01995926 Reviewed-on: http://git.am.freescale.net:8181/9605 Tested-by: Review Code-CDREVIEW <CDREVIEW@freescale.com> Reviewed-by: Jose Rivera <German.Rivera@freescale.com>
2014-03-17fsl_pci_ep: add VF ATMU access supportMinghuan Lian
All VFs of a PF share the common inbound/outbound windows except translation registers of outbound windows. A VF can only change translation registers of outbound windows. A PF can change all ATMU of VF. The patch provides VF ATMU register definition and provides interfaces to access inbound/outbound windows. It also adds PCI_EP_REGION_MEM type to return PF's memory resource. The application can get and reassign the memory resource to VF.

2013-11-06powerpc/scom: Improve debugfs interfaceBenjamin Herrenschmidt
The current debugfs interface to scom is essentially unused and racy. It uses two different files "address" and "data" to perform accesses which is at best impractical for anything but manual use by a developer. This replaces it with an "access" file which represent the entire scom address space which can be lseek/read/writen too. This file only supports accesses that are 8 bytes aligned and multiple of 8 bytes in size. The offset is logically the SCOM address multiplied by 8. Since nothing in userspace exploits that file at the moment, the ABI change is a no-brainer. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Now that (1) the unneeded code is marked 'static' and (2) the code is only used under a C 'if (IS_ENABLED(CONFIG_FB_FSL_DIU))', the compiler can automatically remove the unneeded code, and we don't need the #if or the empty stub functions.

2013-10-29powerpc/pci: Change the DECLARE_PCI_FIXUP_{HEADER => EARLY} macro of pci quirkChunhe Lan
Freescale platform has class code = 0x0b2000, when it boots. This makes kernel PCI bus code to setup these devices resulting into the following notice information when trying to enable them: pci 0000:00:00.0: ignoring class 0x0b2000 (doesn't match header type 01) The above information is outputted by judging value of dev->class before pci_setup_device() function, and the DECLARE_PCI_FIXUP_HEADER quirk runs after pci_setup_device() function. But the DECLARE_PCI_FIXUP_EARLY quirk runs before judging value of dev->class and pci_setup_device() function. So we use the DECLARE_PCI_FIXUP_EARLY macro to fix this issue.
