* [POWERPC] Remove dev_dbg redefinition in drivers/ps3/vuart.cPaul Mackerras2007-04-301-8/+0
| | | | | | | | | Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition of dev_dbg in the !DEBUG case from being a #define to being a static inline. There was code in drivers/ps3/vuart.c to do exactly that, which fails to compile now. This fixes it by removing the redefinition, as the redefinition is now superfluous.

* [POWERPC] ps3: always make sure were running on a PS3Geert Uytterhoeven2007-03-103-2/+15
| | | | | | | | | | | Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that we are actually running on a PS3 (pointed out by Arnd). Correct existing checks in other subsystems/drivers to return -ENODEV instead of zero.

| | | | | | | | | | | | Add PS3 system manager support and the ppc_md routines restart() and power_off(). The system manager provides an event notification mechanism for reporting events like thermal alert and button presses. It also provides support to control system shutdown and startup.

* [POWERPC] ps3: bind interrupt to cpuGeoff Levand2007-02-071-2/+2
| | | | | | | | | | | | Change the PS3 irq allocation routines to take an argument indicating which cpu (processor thread) the interrupt should be serviced on. The current system configuration favors device interrupts that are serviced on cpu0, so that is used as the default.

* [POWERPC] ps3: system bus minor mmio fixBenjamin Herrenschmidt2007-02-071-3/+3
| | | | | | | | | | | | | | Fix two minor bugs in the PS3 system bus mmio region code. First, on error or when freeing a region, retain the bus_addr and len fields to allow subsequent calls to create the region. Second, correct the region address argument to the lv1_unmap_device_mmio_region() call. Fixes modprobe/rmmod of some drivers.

* [POWERPC] ps3: Add vuart supportGeoff Levand2006-12-113-0/+1060
| | | | | | | | | | | | | Adds support for the PS3 virtual UART (vuart). The vuart provides a bi-directional byte stream data link between logical partitions. This is needed for the ps3 graphics driver and the ps3 power control support to be able to communicate with the lv1 policy module.

* [POWERPC] ps3: multiplatform build fixesArnd Bergmann2006-12-041-0/+4
| | | | | | | | | | | | | | | | | | | | | A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. 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>
