2009-06-23Intel-IOMMU, intr-remap: source-id checkingWeidong Han4-3/+136
To support domain-isolation usages, the platform hardware must be capable of uniquely identifying the requestor (source-id) for each interrupt message. Without source-id checking for interrupt remapping , a rouge guest/VM with assigned devices can launch interrupt attacks to bring down anothe guest/VM or the VMM itself. This patch adds source-id checking for interrupt remapping, and then really isolates interrupts for guests/VMs with assigned devices. Because PCI subsystem is not initialized yet when set up IOAPIC entries, use read_pci_config_byte to access PCI config space directly.

2009-06-23Intel-IOMMU, intr-remap: set the whole 128bits of irte when modify/free itWeidong Han1-14/+26
Interrupt remapping table entry is 128bits. Currently, it only sets low 64bits of irte in modify_irte and free_irte. This ignores high 64bits setting of irte, that means source-id setting will be ignored. This patch sets the whole 128bits of irte when modify/free it. Following source-id checking patch depends on this. Signed-off-by: Weidong Han <[email protected]> Signed-off-by: David Woodhouse <[email protected]>
2009-06-23IOMMU Identity Mapping Support (drivers/pci/intel_iommu.c)Fenghua Yu1-60/+254
Identity mapping for IOMMU defines a single domain to 1:1 map all PCI devices to all usable memory. This reduces map/unmap overhead in DMA API's and improve IOMMU performance. On 10Gb network cards, Netperf shows no performance degradation compared to non-IOMMU performance. This method may lose some of DMA remapping benefits like isolation. The patch sets up identity mapping for all PCI devices to all usable memory. In the DMA API, there is no overhead to maintain page tables, invalidate iotlb, flush cache etc. 32 bit DMA devices don't use identity mapping domain, in order to access memory beyond 4GiB. When kernel option iommu=pt, pass through is first tried. If pass through succeeds, IOMMU goes to pass through. If pass through is not supported in hw or fail for whatever reason, IOMMU goes to identity mapping. Signed-off-by: Fenghua Yu <[email protected]> Signed-off-by: David Woodhouse <[email protected]>

2009-06-23mm: fix handling of pagesets for downed cpusDimitri Sivanich1-3/+3
After downing/upping a cpu, an attempt to set /proc/sys/vm/percpu_pagelist_fraction results in an oops in percpu_pagelist_fraction_sysctl_handler(). If a processor is downed then we need to set the pageset pointer back to the boot pageset. Updates of the high water marks should not access pagesets of unpopulated zones (those pointer go to the boot pagesets which would be no longer functional if their size would be increased beyond zero).

2009-06-23rmap: fixup page_referenced() for nommu systemsMike Frysinger1-1/+8
After the recent changes that went into mm/vmscan.c to overhaul stuff, we ended up with these warnings on no-mmu systems: mm/vmscan.c: In function `shrink_page_list': mm/vmscan.c:580: warning: unused variable `vm_flags' mm/vmscan.c: In function `shrink_active_list': mm/vmscan.c:1294: warning: `vm_flags' may be used uninitialized in this function mm/vmscan.c:1242: note: `vm_flags' was declared here This is because the no-mmu function defines page_referenced() to work on the first argument only (the page). It does not clear the vm_flags given to it because for no-mmu systems, they never actually get utilized. Since that is no longer strictly true, we need to set vm_flags to 0 like everyone else so gcc can do proper dead code elimination without annoying us with unused warnings.

2009-06-23mm: pass mm to grab_swap_tokenHugh Dickins3-24/+22
If a kthread happens to use get_user_pages() on an mm (as KSM does), there's a chance that it will end up trying to read in a swap page, then oops in grab_swap_token() because the kthread has no mm: GUP passes down the right mm, so grab_swap_token() ought to be using it. We have not identified a stronger case than KSM's daemon (not yet in mainline), but the issue must have come up before, since RHEL has included a fix for this for years (though a different fix, they just back out of grab_swap_token if current->mm is unset: which is what we first proposed, but using the right mm here seems more correct).

2009-06-23leds: Add options to have GPIO LEDs start on or keep their stateTrent Piepho3-6/+40
There already is a "default-on" trigger but there are problems with it. For one, it's a inefficient way to do it and requires led trigger support to be compiled in. But the real reason is that is produces a glitch on the LED. The GPIO is allocate with the LED *off*, then *later* when the trigger runs it is turned back on. If the LED was already on via the GPIO's reset default or action of the firmware, this produces a glitch where the LED goes from on to off to on. While normally this is fast enough that it wouldn't be noticeable to a human observer, there are still serious problems. One is that there may be something else on the GPIO line, like a hardware alarm or watchdog, that is fast enough to notice the glitch. Another is that the kernel may panic before the LED is turned back on, thus hanging with the LED in the wrong state. This is not just speculation, but actually happened to me with an embedded system that has an LED which should turn off when the kernel finishes booting, which was left in the incorrect state due to a bug in the OF LED binding code. We also let GPIO LEDs get their initial value from whatever the current state of the GPIO line is. On some systems the LEDs are put into some state by the firmware or hardware before Linux boots, and it is desired to have them keep this state which is otherwise unknown to Linux. This requires that the underlying GPIO driver support reading the value of output GPIOs. Some drivers support this and some do not. The platform device binding gains a field in the platform data "default_state" that controls this. There are three constants defined to select from on, off, or keeping the current state. The OpenFirmware binding uses a property named "default-state" that can be set to "on", "off", or "keep". The default if the property isn't present is off.

LEDs driver for National Semiconductor LP3944 Funlight Chip http://www.national.com/pf/LP/LP3944.html This helper chip can drive up to 8 leds, with two programmable DIM modes; it could even be used as a gpio expander but this driver assumes it is used as a led controller. The DIM modes are used to set _blink_ patterns for leds, the pattern is specified supplying two parameters: - period: from 0s to 1.6s - duty cycle: percentage of the period the led is on, from 0 to 100 LP3944 can be found on Motorola A910 smartphone, where it drives the rgb leds, the camera flash light and the displays backlights.

2009-06-23powerpc/85xx: Stop using ppc_md.init on socratesKumar Gala1-3/+3
Match what other 85xx platforms do for of_platform_bus_probe and use machine_device_initcall. This is one small step in killing of ppc_md.init. Signed-off-by: Kumar Gala <[email protected]>

2009-06-23powerpc/qe: add polling timeout to qe_issue_cmd()Timur Tabi1-3/+6
The qe_issue_cmd() function (Freescale PowerPC QUICC Engine library) polls on a register until a status bit changes, but does not include a timeout to handle the situation if the bit never changes. Change the code to use the new spin_event_timeout() macro, which simplifies polling on a register without a timeout.

2009-06-23asm-generic: add dummy pgprot_noncached()Paul Mundt1-0/+4
Most architectures now provide a pgprot_noncached(), the remaining ones can simply use an dummy default implementation, except for cris and xtensa, which should override the default appropriately.
