* iommu/vt-d: Use cmpxchg16b to update posted format IRTE atomicallyFeng Wu2015-10-151-3/+30
| | | | | | | | | | If IRTE is in posted format, the 'pda' field goes across the 64-bit boundary, we need use cmpxchg16b to atomically update it. We only expose posted-interrupt when X86_FEATURE_CX16 is supported and use to update it atomically. Signed-off-by: Feng Wu <feng.wu@intel.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
* iommu/vt-d: Switch from ioremap_cache to memremapDan Williams2015-10-142-13/+15
| | | | | | | | | | In preparation for deprecating ioremap_cache() convert its usage in intel-iommu to memremap. This also eliminates the mishandling of the __iomem annotation in the implementation.

* iommu/vt-d: Create RMRR mappings in newly allocated domainsJoerg Roedel2015-10-051-0/+20
| | | | | | | | | | Currently the RMRR entries are created only at boot time. This means they will vanish when the domain allocated at boot time is destroyed. This patch makes sure that also newly allocated domains will get RMRR mappings. Signed-off-by: Joerg Roedel <jroedel@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NMI entry code that switches to the normal kernel stack needs to be very careful not to clobber any extra stack slots on the NMI stack. The code is fine under the assumption that SWAPGS is just a normal instruction, but that assumption isn't really true. Use SWAPGS_UNSAFE_STACK instead. This is part of a fix for some random crashes that Sasha saw.

This is bad news for a CLBR_NONE operation. Of course, if everything works correctly, once paravirt ops are patched, it gets nopped out, but what if we hit this code before paravirt ops are patched in? This can potentially cause breakage that is very difficult to debug. A more subtle failure is possible here, too: if _paravirt_nop uses the stack at all (even just to push RBP), it will overwrite the "NMI executing" variable if it's called in the NMI prologue. The Xen case, perhaps surprisingly, is fine, because it's already written in asm. Fix all of the cases that default to paravirt_nop (including adjust_exception_frame) with a big hammer: replace paravirt_nop with an asm function that is just a ret instruction. The Xen case may have other problems, so document them. This is part of a fix for some random crashes that Sasha saw.

In this case, it happens that if the bootloader used the NAND and set the DFI arbitration bit, the next access to a static memory controller area, such as an ethernet card, the system bus will stall, and the core will be stalled forever. Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit will be enabled the pxa3xx-nand driver on need anyway. The only left requirement is that upon pxa3xx-nand removal, the bit should be cleared before the clock is disabled. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

Some very few 10 something boards have been created and stopped production till the latest modifications were done (PMIC USB interrupt, LDO4 etc) - and all of those boards are now getting scrapped.. If there are any (as per tracking information, there should not be any), TI should be contacted to have them replaced.

This can fail if the system is booting on bootloader configured PLL values until the clock framework driver for the PLL is implemented. Let's just WARN instead, this will provide helpful information for anybody bringing up a new SoC what needs to be fixed. This allows to boot dm814x that's still missing the PLL driver.

This is the valid case, and omap_device_late_init() should not idle such devices. To fix this issue, the value of omap_device->_driver_status field should be checked not only for BUS_NOTIFY_BOUND_DRIVER (driver is present and has been bound to device successfully), but also checked for BUS_NOTIFY_BIND_DRIVER (driver about to be bound) - which means driver is present and there was try to bind it to device.
