2012-06-24booke_206_tlbwe: Discard invalid bits in MAS2Fabien Chouteau
The size of EPN field in MAS2 depends on page size. This patch adds a mask to discard invalid bits in EPN field. Definition of EPN field from e500v2 RM: EPN Effective page number: Depending on page size, only the bits associated with a page boundary are valid. Bits that represent offsets within a page are ignored and should be cleared. There is a similar (but more complicated) definition in PowerISA V2.06.

2012-06-24PPC: mpc8544ds: Span initial TLB entry over as much RAM as we needAlexander Graf
The initial TLB entry is supposed to help us run the guest -kernel payload. This means the guest needs to be able to access its own memory, the initrd memory and the device tree. So far we only statically reserved a TLB entry from [0;256M[. This patch fixes it to span from [0;dt_end[, allowing the guest payload to access everything initially.

Add an explicit CPUPPCState parameter instead of relying on AREG0 and rename op_helper.c (which only contains load and store helpers) to mem_helper.c. Remove AREG0 swapping in tlb_fill().

2012-06-21xilinx_timer: Fixed deadlock issuePeter A. G. Crosthwaite
The timer was deadlocking when the interval was set too low. It would cause a flood of timer events and the CPU would halt indefinately. This is a known issue and theres a generic workaround in place in ptimer on ptimer_set_limit(), however the Xilinx timer uses ptimer_set_count() instead of set_limit. Changed the call to set_count() to an equivalent call of set_limit() instead, which brings the workaround into play. Signed-off-by: Peter A. G.

2012-06-19Allow machines to configure the QEMU_VERSION that's exposed via hardwareCrístian Viana
QEMU exposes its version to the guest's hardware and in some cases that is wrong (e.g. Windows prints messages about driver updates when you switch the QEMU version). There is a new field now on the struct QEmuMachine, hw_version, which may contain the version that the specific machine should report. If that field is set, then that machine will report that version to the guest. Signed-off-by: Crístian Viana <vianac@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-06-19Add PIIX4 properties to control PM system states.Gleb Natapov
This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.
