2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>

2011-09-10Gdbstub: Fix back-trace on SPARC32Fabien Chouteau
Gdb expects all registers windows to be flushed in ram, which is not the case in Qemu. Therefore the back-trace generation doesn't work. This patch adds a function to handle reads (and only read) in stack frames as if windows were flushed.

2011-07-21SPARC64: implement addtional MMU faults related to nonfaulting loadTsuneo Saito
This patch implements MMU faults caused by TTE.NFO and TTE.E: - access other than nonfaulting load to a page marked NFO should raise data_access_exception - nonfaulting load to a page marked with E bit should raise data_access_exception To distinguish nonfaulting loads, this patch extends (abuses?) the rw argument of get_physical_address_data(). rw is set to 4 on nonfaulting loads.

2011-07-21SPARC64: fix fault status overwritten on nonfaulting loadTsuneo Saito
cpu_get_phys_page_nofault() calls get_physical_address() twice, that results in overwriting the fault status in the SFSR. We need this change in order for nonfaulting loads to raising MMU faults as normal loads do. Also removed the call to cpu_get_physical_page_desc() since we are going to modify nonfaulting loads raising MMU faults.

2011-07-21SPARC64: split cpu_get_phys_page_debug() from cpu_get_phys_page_nofault()Tsuneo Saito
This patch makes cpu_get_phys_page_debug() independent from cpu_get_phys_page_nofault() in advance of implementing nonfaulting load. This also modifies cpu_get_phys_page_nofault() to be compiled only on TARGET_SPARC64 because it is not required on SPARC32.

2010-03-17Large page TLB flushPaul Brook
QEMU uses a fixed page size for the CPU TLB. If the guest uses large pages then we effectively split these into multiple smaller pages, and populate the corresponding TLB entries on demand. When the guest invalidates the TLB by virtual address we must invalidate all entries covered by the large page. However the address used to invalidate the entry may not be present in the QEMU TLB, so we do not know which regions to clear. Implementing a full vaiable size TLB is hard and slow, so just keep a simple address/mask pair to record which addresses may have been mapped by large pages. If the guest invalidates this region then flush the whole TLB. Signed-off-by: Paul Brook <paul@codesourcery.com>
