2011-03-15powerpc/85xx: Fix writing to spin table 'cpu-release-addr' on ppc64eKumar Gala1-1/+5
If the spin table is located in the linear mapping (which can happen if we have 4G or more of memory) we need to access the spin table via a cacheable coherent mapping like we do on ppc32 (and do explicit cache flush). See the following commit for the ppc32 version of this issue: commit d1d47ec6e62ab08d2ebb925fd9203abfad3adfbf Author: Peter Tyser <[email protected]> Date: Fri Dec 18 16:50:37 2009 -0600 powerpc/85xx: Fix SMP when "cpu-release-addr" is in lowmem Signed-off-by: Kumar Gala <[email protected]>
2011-03-11powerpc/pseries: Disable MSI using new interface if possibleNishanth Aravamudan1-2/+12
On upcoming hardware, we have a PCI adapter with two functions, one of which uses MSI and the other uses MSI-X. This adapter, when MSI is disabled using the "old" firmware interface (RTAS_CHANGE_FN), still signals an MSI-X interrupt and triggers an EEH. We are working with the vendor to ensure that the hardware is not at fault, but if we use the "new" interface (RTAS_CHANGE_MSI_FN) to disable MSI, we also automatically disable MSI-X and the adapter does not appear to signal any stray MSI-X interrupt.

If firmware allows us to map all of a partition's memory for DMA on a particular bridge, create a 1:1 mapping of that memory. Add hooks for dealing with hotplug events. Dynamic DMA windows can use larger than the default page size, and we use the largest one possible.

A customer of ours, complained that when setting the reset vector back to 0, it trashed other data and hung their box. They noticed when only 4 bytes were set to 0 instead of 8, everything worked correctly. Mathew pointed out: | | We're supposed to be resetting trampoline_phys_low and | trampoline_phys_high here, which are two 16-bit values. | Writing 64 bits is definitely going to overwrite space | that we're not supposed to be touching. | So limit the area modified to u32.

2011-02-25omap4: prcm: Fix the CPUx clockdomain offsetsSantosh Shilimkar1-2/+2
CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base. The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power domain control register Fix the same. The autogen scripts is fixed thanks to Benoit Cousson With the old value, the clockdomain code would access the *_PWRSTCTRL.POWERSTATE field when it thought it was accessing the *_CLKSTCTRL.CLKTRCTRL field. In the worst case, this could cause system power management to behave incorrectly.
