| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Popular glibc based distributions[1] require minimum 2.6.32 as kernel version. For some targets 2.6.18 would be enough, but dropping so low would mean some suboptimal system calls could get used. Set the minimum kernel advertized to 2.6.32 for all architectures but aarch64 to ensure working qemu linux-user in case host kernel is older.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Glibc when built for newer kernels assumes that the sendmmsg syscall is available. Without it, dns resolution simply fails to work. Wrap the syscall with existing infrastructure so that we don't have a host dependency on sendmmsg. To avoid locking the same area of guest memory twice (which will break if DEBUG_REMAP is defined) we pull the lock/unlock part of do_sendrecvmsg() out into its own function so the actual implementation can be shared.

The exclusive load remembers the address and loaded value. The exclusive store throws an an exception which uses those values to check for equality in a proper exclusive region. This is not actually the architecture mandated semantics (for either AArch32 or AArch64) but it is close enough for typical guest code sequences to work correctly, and saves us from having to monitor all guest stores. It's fairly easy to come up with test cases where we don't behave like hardware - we don't for example model cache line behaviour. However in the common patterns this works, and the existing 32 bit ARM exclusive access implementation has the same limitations. AArch64 also implements new acquire/release loads/stores (which may be either exclusive or non-exclusive). These imposes extra ordering constraints on memory operations (ie they act as if they have an implicit barrier built into them). As TCG is single-threaded all our barriers are no-ops, so these just behave like normal loads and stores.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for adding support for A64 load/store exclusive instructions, widen the fields in the CPU state struct that deal with address and data values for exclusives from 32 to 64 bits. Although in practice AArch64 and AArch32 exclusive accesses will be generally separate there are some odd theoretical corner cases (eg you should be able to do the exclusive load in AArch32, take an exception to AArch64 and successfully do the store exclusive there), and it's also easier to reason about. The changes in semantics for the variables are: exclusive_addr -> extended to 64 bits; -1ULL for "monitor lost", otherwise always < 2^32 for AArch32 exclusive_val -> extended to 64 bits. 64 bit exclusives in AArch32 now use the high half of exclusive_val instead of a separate exclusive_high exclusive_high -> is no longer used in AArch32; extended to 64 bits as it will be needed for AArch64's pair-of-64-bit-values exclusives. exclusive_test -> extended to 64 bits, as it is an address. Since this is a linux-user-only field, in arm-linux-user it will always have the top 32 bits zero. exclusive_info -> stays 32 bits, as it is neither data nor address, but simply holds register indexes etc. AArch64 will be able to fit all its information into 32 bits as well. Note that the refactoring of gen_store_exclusive() coincidentally fixes a minor bug where ldrexd would incorrectly update the first CPU register even if the load for the second register faulted.

|/ | | | | | | | | | | | | | | | | | | | | | | | | The common pattern for system registers in a 64-bit capable ARM CPU is that when in AArch32 the cp15 register is a view of the bottom 32 bits of the 64-bit AArch64 system register; writes in AArch32 leave the top half unchanged. The most natural way to model this is to have the state field in the CPU struct be a 64 bit value, and simply have the AArch32 TCG code operate on a pointer to its lower half. For aarch64-linux-user the only registers we need to share like this are the thread-local-storage ones. Widen their fields to 64 bits and provide the 64 bit reginfo struct to make them visible in AArch64 state. Note that minor cleanup of the AArch64 system register encoding space means We can share the TPIDR_EL1 reginfo but need split encodings for TPIDR_EL0 and TPIDRRO_EL0. Since we're touching almost every line in QEMU that uses the c13_tls* fields in this patch anyway, we take the opportunity to rename them in line with the standard ARM architectural names for these registers.

* linux-user: Fix stat64 syscall for SPARC64Stefan Weil2013-11-072-3/+17
| | | | | | | | | | | | Some targets use a stat64 structure for the stat64 syscall while others use a stat structure. SPARC64 used the wrong kind. Instead of extending the conditional compilation in syscall.c, now a macro TARGET_HAS_STRUCT_STAT64 is defined whenever a target has a target_stat64.
