2019-02-15gdbstub: Send a reply to the vKill packet.Sandra Loosemore
Per the GDB remote protocol documentation https://sourceware.org/gdb/current/onlinedocs/gdb/Packets.html#index-vKill-packet the debug stub is expected to send a reply to the 'vKill' packet. At least some versions of GDB crash if the gdb stub simply exits without sending a reply. This patch fixes QEMU's gdb stub to conform to the expected behavior. Note that QEMU's existing handling of the legacy 'k' packet is correct: in that case GDB does not expect a reply, and QEMU does not send one.

Fix a typo which meant we were wiring every expansion IRQ line to external IRQ 0 on CPU 0 and to external IRQ 1 on CPU 1.

2019-02-15hw/intc/armv7m_nvic: Allow byte accesses to SHPR1Peter Maydell
The code for handling the NVIC SHPR1 register intends to permit byte and halfword accesses (as the architecture requires). However the 'case' line for it only lists the base address of the register, so attempts to access bytes other than the first one end up in the "bad write" default logic. This bug was added accidentally when we split out the SHPR1 logic from SHPR2 and SHPR3 to support v6M.

2019-02-15arm: Allow system registers for KVM guests to be changed by QEMU codePeter Maydell
At the moment the Arm implementations of kvm_arch_{get,put}_registers() don't support having QEMU change the values of system registers (aka coprocessor registers for AArch32). This is because although kvm_arch_get_registers() calls write_list_to_cpustate() to update the CPU state struct fields (so QEMU code can read the values in the usual way), kvm_arch_put_registers() does not call write_cpustate_to_list(), meaning that any changes to the CPU state struct fields will not be passed back to KVM. The rationale for this design is documented in a comment in the AArch32 kvm_arch_put_registers() -- writing the values in the cpregs list into the CPU state struct is "lossy" because the write of a register might not succeed, and so if we blindly copy the CPU state values back again we will incorrectly change register values for the guest. The assumption was that no QEMU code would need to write to the registers. However, when we implemented debug support for KVM guests, we broke that assumption: the code to handle "set the guest up to take a breakpoint exception" does so by updating various guest registers including ESR_EL1. Support this by making kvm_arch_put_registers() synchronize CPU state back into the list. We sync only those registers where the initial write succeeds, which should be sufficient.

2019-02-15target/arm: expose CPUID registers to userspaceAlex Bennée
A number of CPUID registers are exposed to userspace by modern Linux kernels thanks to the "ARM64 CPU Feature Registers" ABI. For QEMU's user-mode emulation we don't need to emulate the kernels trap but just return the value the trap would have done. To avoid too much #ifdef hackery we process ARMCPRegInfo with a new helper (modify_arm_cp_regs) before defining the registers. The modify routine is driven by a simple data structure which describes which bits are exported and which are fixed.

2019-02-14hw/mips_cpc: kick a VP when putting it into Run statewqMiodrag Dinic
While testing mttcg VP0 could get stuck in a loop waiting for other VPs to come up (which never actually happens). To fix this, kick VPs while they are being powered up by Cluster Power Controller in an async task which is triggered once the host thread is being spawned.

2019-02-14target/mips: hold BQL in mips_vpe_wake()Goran Ferenc
Hold BQL whenever mips_vpe_wake() is invoked. Without this patch, MIPS MT with MTTCG enabled triggers an abort in tcg_handle_interrupt() due to an unlocked access to cpu_interrupt(). This patch makes sure that the BQL is held in this case.

Make sure BQL is held for all interrupt requests. For MTTCG-enabled configurations, handling soft and hard interrupts between vCPUs must be properly locked. By acquiring BQL, make sure all paths triggering an IRQ are synchronized.

2019-02-14target/mips: compare virtual addresses in LL/SC sequenceLeon Alrae
Do only virtual addresses comaprisons in LL/SC sequence emulations. Until this patch, physical addresses had been compared in SC part of LL/SC sequence, even though such comparisons could be avoided. Getting rid of them allows throwing away SC helpers and having common SC implementations in user and system mode, avoiding the need for two separate implementations selected by #ifdef CONFIG_USER_ONLY. Correct guest software should not rely on LL/SC if they accesses the same physical address via different virtual addresses or if page mapping gets changed between LL/SC due to manipulating TLB entries. MIPS Instruction Set Manual clearly says that an RMW sequence must use the same address in the LL and SC (virtual address, physical address, cacheability and coherency attributes must be identical). Otherwise, the result of the SC is not predictable. This patch takes advantage of this fact and removes the virtual->physical address translation from SC helper. lladdr served as Coprocessor 0 LLAddr register which captures physical address of the most recent LL instruction, and also lladdr was used for comparison with following SC physical address. This patch changes the meaning of lladdr - now it will only keep the virtual address of the most recent LL. Additionally, CP0_LLAddr field is introduced which is the actual Coperocessor 0 LLAddr register that guest can access.
