2023-10-12kvm: Add stub for kvm_get_max_memslots()David Hildenbrand
We'll need the stub soon from memory device context. While at it, use "unsigned int" as return value and place the declaration next to kvm_get_free_memslots().

2023-10-12kvm: Return number of free memslotsDavid Hildenbrand
Let's return the number of free slots instead of only checking if there is a free slot. While at it, check all address spaces, which will also consider SMM under x86 correctly. This is a preparation for memory devices that consume multiple memslots.

2023-10-11plugins: Set final instruction count in plugin_gen_tb_endMatt Borgerson
Translation logic may partially decode an instruction, then abort and remove the instruction from the TB. This can happen for example when an instruction spans two pages. In this case, plugins may get an incorrect result when calling qemu_plugin_tb_n_insns to query for the number of instructions in the TB. This patch updates plugin_gen_tb_end to set the final instruction count.

The tcg/tcg.h header is a big bucket, containing stuff related to the translators and the JIT backend.

2023-09-29accel/kvm/kvm-all: Handle register access errorsAkihiko Odaki
A register access error typically means something seriously wrong happened so that anything bad can happen after that and recovery is impossible. Even failing one register access is catastorophic as architecture-specific code are not written so that it torelates such failures. Make sure the VM stop and nothing worse happens if such an error occurs.

2023-09-28accel/tcg: Always require can_do_ioRichard Henderson
Require i/o as the last insn of a TranslationBlock always, not only with icount. This is required for i/o that alters the address space, such as a pci config space write.

2023-09-28accel/tcg: Always set CF_LAST_IO with CF_NOIRQRichard Henderson
Without this we can get see loops through cpu_io_recompile, in which the cpu makes no progress. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-09-28accel/tcg: Improve setting of can_do_io at start of TBRichard Henderson
Initialize can_do_io to true if this the TB has CF_LAST_IO and will consist of a single instruction. This avoids a set to 0 followed immediately by a set to 1. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
