* xen64: fix calls into hypercall pageJeremy Fitzhardinge2008-07-16
| | | | | | | | | | | | | | | | | | | | | The 64-bit calling convention for hypercalls uses different registers from 32-bit. Annoyingly, gcc's asm syntax doesn't have a way to specify one of the extra numeric reigisters in a constraint, so we must use explicitly placed register variables. Given that we have to do it for some args, may as well do it for all. Also fix syntax gcc generates for the call instruction itself. We need a plain direct call, but the asm expansion which works on 32-bit generates a rip-relative addressing mode in 64-bit, which is treated as an indirect call. The alternative is to pass the hypercall page offset into the asm, and have it add it to the hypercall page start address to generate the call.

* xen: add xen_arch_resume()/xen_timer_resume hook for ia64 supportIsaku Yamahata2008-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | add xen_timer_resume() hook. Timer resume should be done after event channel is resumed. add xen_arch_resume() hook when ipi becomes usable after resume. After resume, some cpu specific resource must be reinitialized on ia64 that can't be set by another cpu. However available hooks is run once on only one cpu so that ipi has to be used. During stop_machine_run() ipi can't be used because interrupt is masked. So add another hook after stop_machine_run(). Another approach might be use resume hook which is run by device_resume(). However device_resume() may be executed on suspend error recovery path. So it is necessary to determine whether it is executed on real resume path or error recovery path.

The main impetus for this compat set is the need to support partition migration, especially from processor P(n) to processor P(n+1), where performance software that's running in the new partition may not be knowledgeable about processor P(n+1). If a performance tool determines it does not support the physical processor, but is told (via the PPC_FEATURE_PSERIES_PERFMON_COMPAT bit) that the processor supports the notion of the PMU compat set, then the performance tool can surface just those events to the user of the tool. PPC_FEATURE_PSERIES_PERFMON_COMPAT indicates that the PMU supports at least this basic subset of events which is compatible across POWER processor lines.

Added nodes include: mbx - opengl coprocessor nfc - nand flash controller cpld-pic - on board cpld rtc clock - clock control pmc - power management control gpio mscan - can module i2c axe - audio coprocessor display - display interface unit mdio ethernet usb ioctl - pin config pata ac97 - PSC configured as AC97 pscfifo - psc fifo configuration dma pci Fix typo in header changing MDS to ADS. Add a compatible property of the form "fsl,mpc5121-..." to nodes missing one. Changed localbus compatible to fsl,mpc5121-localbus, this does not break anything because the only code that uses it finds it via the node name, not compatible.

The 8-Bit write combine timer (Bits 24..31) should be also set to a reasonable value _greater zero_ (0x08 = default) since setting it to 0x00 leads to _very poor_ performance as a PCI target since external burst won't be possible at all. Setting the WCT to 0x08 (cache-line size) leads to good overall perfomance. Signed-off-by: Andre Schwarz <andre.schwarz@matrix-vision.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

This introduce support for non-atomic PTE operations in pgtable-ppc32.h and removes write back to the PTE from the TLB miss handlers. In addition, the DSI interrupt code no longer tries to fixup write permission, this is left to generic code, and _PAGE_HWWRITE is gone.
