2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-880/+0
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-10-31target-sparc: Add MMU_PHYS_IDXRichard Henderson1-18/+29
It's handy to have a mmu idx for physical addresses, so that mmu disabled and physical access asis can use the same path as normal accesses. Tested-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: Richard Henderson <rth@twiddle.net>
2016-05-19cpu: move exec-all.h inclusion out of cpu.hPaolo Bonzini1-0/+1
exec-all.h contains TCG-specific definitions. It is not needed outside TCG-specific files such as translate.c, exec.c or *helper.c. One generic function had snuck into include/exec/exec-all.h; move it to include/qom/cpu.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1453832250-766-7-git-send-email-peter.maydell@linaro.org
2015-09-11tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt1-1/+1
This is set to true when the index is for an instruction fetch translation. The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS acessors. All targets ignore it for now, and all other callers pass "false". This will allow targets who wish to split the mmu index between instruction and data accesses to do so. A subsequent patch will do just that for PowerPC.

2014-12-16qemu-log: add log category for MMU infoAntony Pavlov1-4/+3
Running barebox on qemu-system-mips* with '-d unimp' overloads stderr by very very many mips_cpu_handle_mmu_fault() messages: mips_cpu_handle_mmu_fault address=b80003fd ret 0 physical 00000000180003fd prot 3 mips_cpu_handle_mmu_fault address=a0800884 ret 0 physical 0000000000800884 prot 3 mips_cpu_handle_mmu_fault pc a080cd80 ad b80003fd rw 0 mmu_idx 0 So it's very difficult to find LOG_UNIMP message. The mips_cpu_handle_mmu_fault() messages appear on enabling ANY logging! It's not very handy. Adding separate log category for *_cpu_handle_mmu_fault() logging fixes the problem.

2013-07-23cpu: Introduce CPUClass::memory_rw_debug() for target_memory_rw_debug()Andreas Färber1-3/+5
Make inline target_memory_rw_debug() always available and change its argument to CPUState. Let it check if CPUClass::memory_rw_debug provides a specialized callback and fall back to cpu_memory_rw_debug() otherwise. The only overriding implementation is for 32-bit sparc. This prepares for changing GDBState::g_cpu to CPUState. Signed-off-by: Andreas Färber <afaerber@suse.de>

Change breakpoint_invalidate() argument to CPUState alongside.

2013-07-04memory: add ref/unref callsPaolo Bonzini1-0/+1
Add ref/unref calls at the following places: - places where memory regions are stashed by a listener and used outside the BQL (including in Xen or KVM). - memory_region_find callsites - creation of aliases and containers (only the aliased/contained region gets a reference to avoid loops) - around calls to del_subregion/add_subregion, where the region could disappear after the first call Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-06-20memory: make section size a 128-bit integerPaolo Bonzini1-1/+1
So far, the size of all regions passed to listeners could fit in 64 bits, because artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes An IOMMU however cannot be eliminated by the memory core, and may have an artificial size, hence we may need 65 bits to represent its size.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-19/+19
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.
