2013-11-20target-openrisc: Remove executable flag for every pageSebastian Macke
Pages should be flagged executable only if the tlb executable flag is set or the mmu is off. Signed-off-by: Sebastian Macke <sebastian@macke.de> Reviewed-by: Jia Liu <proljc@gmail.com> Signed-off-by: Jia Liu <proljc@gmail.com>

memory Where *software* leaves 0x0000 - 0x2000 unmapped, the hardware should still allow for this area to be mapped. Signed-off-by: Sebastian Macke <sebastian@macke.de> Signed-off-by: Stefan Kristiansson <stefan.kristiansson@saunalahti.fi> Reviewed-by: Jia Liu <proljc@gmail.com>
2013-10-03target-openrisc: Correct handling of page faults.Sebastian Macke
The result of (rw & 0) is always zero and therefore a logic false. The whole comparison will therefore never be executed, it is a obvious bug, we should use !(rw & 1) here. Signed-off-by: Sebastian Macke <sebastian@macke.de> Reviewed-by: Jia Liu <proljc@gmail.com>
2013-07-23cpu: Turn cpu_get_phys_page_debug() into a CPUClass hookAndreas Färber
Change breakpoint_invalidate() argument to CPUState alongside. Since all targets now assign a softmmu-only field, we can drop helpers cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd(). Prepares for changing cpu_memory_rw_debug() argument to CPUState. Acked-by: Max Filippov <jcmvbkbc@gmail.com> (for xtensa) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-27target-openrisc: Clean up triple QOM castsAndreas Färber
Instead of calling openrisc_env_get_cpu(), casting to CPU() via the ENV_GET_CPU() compatibility macro and casting back to OPENRISC_CPU(), just call openrisc_env_get_cpu() directly. ENV_GET_CPU() is meant as workaround for target-independent code only. Signed-off-by: Andreas Färber <afaerber@suse.de>

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
