* Fix swiotlb_sync_single_range()Keir Fraser2007-07-21
| | | | | | | | | | | | | | | | | | | If the swiotlb maps a multi-slab region, swiotlb_sync_single_range() can be invoked to sync a sub-region which does not include the first slab. Unfortunately io_tlb_orig_addr[] is only initialised for the first slab, and hence the call to sync_single() will read a garbage orig_addr in this case. This patch fixes the issue by initialising all mapped slabs in io_tlb_orig_addr[]. It also correctly adjusts the buffer pointer in sync_single() to handle the case that the given dma_addr is not aligned on a slab boundary.

The output-device setting, for example, must be resolved via an alias or similar to a full path name to the console device. Paths also contain an optional set of 'options', which starts with a colon at the end of the path. The option area is used to specify which of two serial ports ('a' or 'b') the path refers to when a device node drives multiple ports. 'a' is assumed if the option specification is missing. This was caught by the UltraSPARC-T1 simulator. The 'output-device' property was set to 'ttya' and we didn't pick upon the fact that this is an OBP alias set to '/virtual-devices/console'. Instead we saw it as the first serial console device, instead of the hypervisor console. The infrastructure is now there to take advantage of this to resolve the console correctly even in multi-head situations in fbcon too. Thanks to Greg Onufer for the bug report.

So on completion of the VBI DMA the driver no longer knew that that DMA transfer was for VBI data. And this in turn caused havoc with the card's DMA engine.

In detail: - the per-node free_spus and active_list are gone. Instead struct spu gained an alloc_state member telling whether the spu is free or not - the per-node spus array is now locked by a per-node mutex, which takes over from the global spu_lock and the per-node active_mutex - the spu_alloc* and spu_free function are gone as the state change is now done inline in the spufs code. This allows some more sharing of code for the affinity vs normal case and more efficient locking - some little refactoring in the affinity code for this locking scheme Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>

In addition, a 'cell' subdirectory was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code. Exports spu_set_profile_private_kref and spu_get_profile_private_kref which are used by OProfile to store private profile information in spufs data structures. Also incorporated several fixes from other patches (rrn). Check pointer returned from kzalloc. Eliminated unnecessary cast. Better error handling and cleanup in the related area. 64-bit unsigned long parameter was being demoted to 32-bit unsigned int and eventually promoted back to unsigned long.

This property is present in current version of Malta firmware. Example of vicinity properties for a node in Malta: Node: Vicinity property contains phandles of: spe@0 [ spe@100000 , mic-tm@50a000 ] spe@100000 [ spe@0 , spe@200000 ] spe@200000 [ spe@100000 , spe@300000 ] spe@300000 [ spe@200000 , bif0@512000 ] spe@80000 [ spe@180000 , mic-tm@50a000 ] spe@180000 [ spe@80000 , spe@280000 ] spe@280000 [ spe@180000 , spe@380000 ] spe@380000 [ spe@280000 , bif0@512000 ] Only spe@* have a vicinity property (e.g., bif0@512000 and mic-tm@50a000 do not have it).
