2010-07-09powerpc/book3e: Hookup doorbells exceptions on 64-bit Book3EBenjamin Herrenschmidt1-4/+17
Note that critical doorbells are an unimplemented stub just like other critical or machine check handlers, since we haven't done support for "levelled" exceptions yet. Signed-off-by: Benjamin Herrenschmidt <[email protected]>

2009-08-28powerpc/book3e-64: Add support to initial_tlb_book3e for non-HES TLBKumar Gala1-4/+200
We now search through TLBnCFG looking for the first array that has IPROT support (we assume that there is only one). If that TLB has hardware entry select (HES) support we use the existing code and with the proper TLB select (the HES code still needs to clean up bolted entries from firmware). The non-HES code is pretty similiar to the 32-bit FSL Book-E code but does make some new assumtions (like that we have tlbilx) and simplifies things down a bit.

2009-08-28powerpc/book3e-64: Add helper function to setup IVORsKumar Gala1-0/+19
Not all 64-bit Book-3E parts will have fixed IVORs so add a function that cpusetup code can call to setup the base IVORs (0..15) to match the fixed offsets. We need to 'or' part of interrupt_base_book3e into the IVORs since on parts that have them the IVPR doesn't extend as far down.

2009-08-28powerpc/book3e-64: Wait til generic_calibrate_decr to enable decrementerKumar Gala1-2/+4
Match what we do on 32-bit Book-E processors and enable the decrementer in generic_calibrate_decr. We need to make sure we disable the decrementer early in boot since we currently use lazy (soft) interrupt on 64-bit Book-E and possible get a decrementer exception before we are ready for it.

2009-08-20powerpc: Remaining 64-bit Book3E supportBenjamin Herrenschmidt1-0/+784
This contains all the bits that didn't fit in previous patches :-) This includes the actual exception handlers assembly, the changes to the kernel entry, other misc bits and wiring it all up in Kconfig. Signed-off-by: Benjamin Herrenschmidt <[email protected]>
