* powerpc/85xx: Add host-pci(e) bridge only for RCPrabhakar Kushwaha2011-06-271-0/+13
| | | | | | | | | | | FSL PCIe controller can act as agent(EP) or host(RC). Under Agent(EP) mode the controller will be configured by the host system. So its not required to be registered with the PCI(e) sub-system. We only register the controller if its configured in host(RC) mode.

These functions should be assigned to various function pointers of the ppc_md structure during the .probe() function for the board: ppc_md.restart = fsl_hv_restart; ppc_md.power_off = fsl_hv_halt; ppc_md.halt = fsl_hv_halt; Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc: introduce the ePAPR embedded hypervisor vmpic driverAshish Kalra2011-06-274-0/+347
| | | | | | | | | | | | | | | | | | | | | | The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

* powerpc: introduce ePAPR embedded hypervisor hcall interfaceTimur Tabi2011-06-272-0/+1157
| | | | | | | | | | | | | | | | | | ePAPR hypervisors provide operating system services via a "hypercall" interface. The following steps need to be performed to make an hcall: 1. Load r11 with the hcall number 2. Load specific other registers with parameters 3. Issue instrucion "sc 1" 4. The return code is in r3 5. Other returned parameters are in other registers. To provide this service to the kernel, these steps are wrapped in inline assembly functions. Standard ePAPR hcalls are in epapr_hcalls.h, and Freescale extensions are in fsl_hcalls.h.

* powerpc/85xx: Save scratch registers to thread info instead of using SPRGs.Ashish Kalra2011-06-225-40/+63
| | | | | | | | | | | | | | We expect this is actually faster, and we end up needing more space than we can get from the SPRGs in some instances. This is also useful when running as a guest OS - SPRGs4-7 do not have guest versions. 8 slots are allocated in thread_info for this even though we only actually use 4 of them - this allows space for future code to have more scratch space (and we know we'll need it for things like hugetlb).

* powerpc: Avoid extra indirect function call in sending IPIsPaul Mackerras2011-06-206-9/+19
| | | | | | | | | | | | | | | On many platforms (including pSeries), smp_ops->message_pass is always smp_muxed_ipi_message_pass. This changes arch/powerpc/kernel/smp.c so that if smp_ops->message_pass is NULL, it calls smp_muxed_ipi_message_pass directly. This means that a platform doesn't need to set both .message_pass and .cause_ipi, only one of them. It is a slight performance improvement in that it gets rid of an indirect function call at the expense of a predictable conditional branch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCIe cards ship with a PCI-PCIe bridge which is not visible as a PCI device in Linux. But the device-id of the bridge is present in the IOMMU tables which causes a boot crash in the IOMMU driver. This patch fixes by removing these cards from the IOMMU handling.

Instead it should use probe_kernel_read(). This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting the KGDB special breakpoint upon SysRq+g being seen. The problem was that die_if_no_fixup() was failing to read the opcode of the instruction that caused the exception, and thus not fixing up the exception. This caused gdb to get a S04 response to the $? request in its remote protocol rather than S05 - which would then cause it to continue with $C04 rather than $c in an attempt to pass the signal onto the inferior process. The kernel, however, does not support $Cnn, and so objects by returning an E22 response, indicating an error. gdb does not expect this and prints: warning: Remote failure reply: E22 and then returns to the gdb command prompt unable to continue.

If a kvm guest accesses guest real memory that doesnt exist, the page fault handler calls the sie hook, which then rewrites the return psw from sie_inst to either sie_exit or sie_reenter. On return, the page fault handler will then detect the wrong access as a kernel fault causing a kernel oops in sie_reenter or sie_exit. We have to add these two addresses to the exception table to allow graceful exits.

Increase the delay for PBIAS to stabilize. Wait for PBIAS and timeout if not. Resolves MMC/SD failure on OMAP4 "Pbias Voltage is not same as LDO" Signed-off-by: Balaji T K <balajitk@ti.com> Acked-by: Kishore Kadiyala <kishore.kadiyala@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
