| * | | [POWERPC] typo fix and whitespace cleanup on mpc52xx-uart driverGrant Likely2006-12-041-59/+57Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Single typo fix and whitespace changes. In preparation for heavy changes to this driver when support for arch/powerpc is added. Since the driver will be changing significantly anyway, then may as well take the opportunity to clean it up first.

Add a definition for hard_irq_enable() just for completeness. This allows (KEXEC=y && PPC32=y) to build again. Broken since d04c56f73c30a5e593202ecfcf25ed43d42363a2.

The patch is required to solve kdump boot issue when the kdump kernel is booted with parameter "maxcpus=1". XICS init code tries to match the current boot cpu id with "reg" property in each CPU node in the device tree. But CPU node is created only for primary thread CPU ids and "reg" property only reflects primary CPU ids. So when a kernel is booted on a secondary cpu thread above condition will never meet and the default distribution server is left as zero. This leads to route the interrupts to CPU 0, but which is not online at this time. We use ibm,ppc-interrupt-server#s to check for both primary and secondary CPU ids. Accordingly default distribution server value is initialized from "ibm,ppc-interrupt-gserver#s" property. We loop through ibm,ppc-interrupt-gserver#s property to find the global distribution server from the last entry that matches with boot cpuid.

This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
