* Remove unused function parameters from gen_pc_load and rename the functionStefan Weil2011-04-201-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Function gen_pc_load was introduced in commit d2856f1ad4c259e5766847c49acbb4e390731bd4. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10402f1644128b66414ca8f86bdea9ae7c. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error). Cc: Aurelien Jarno <[email protected]> Reviewed-by: Peter Maydell <[email protected]> Signed-off-by: Stefan Weil <[email protected]>
* Fix conversions from pointer to tcg_target_longStefan Weil2011-04-091-1/+1
| | | | | | | | | | | | tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long (suggested by Blue Swirl). These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64.

* Large page TLB flushPaul Brook2010-03-171-2/+3
| | | | | | | | | | | | | | | | | | 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 <[email protected]>
