2024-06-19accel/tcg: Fix typo causing tb->page_addr[1] to not be recordedAnton Johansson
For TBs crossing page boundaries, the 2nd page will never be recorded/removed, as the index of the 2nd page is computed from the address of the 1st page. This is due to a typo, fix it.

2024-06-04cpu: move Qemu[Thread|Cond] setup into common codeAlex Bennée
Aside from the round robin threads this is all common code. By moving the halt_cond setup we also no longer need hacks to work around the race between QOM object creation and thread creation. It is a little ugly to free stuff up for the round robin thread but better it deal with its own specialises than making the other accelerators jump through hoops.

2024-05-30accel/tcg: Make TCGCPUOps::cpu_exec_halt return bool for whether to haltPeter Maydell
The TCGCPUOps::cpu_exec_halt method is called from cpu_handle_halt() when the CPU is halted, so that a target CPU emulation can do anything target-specific it needs to do. (At the moment we only use this on i386.) The current specification of the method doesn't allow the target specific code to do something different if the CPU is about to come out of the halt state, because cpu_handle_halt() only determines this after the method has returned. (If the method called cpu_has_work() itself this would introduce a potential race if an interrupt arrived between the target's method implementation checking and cpu_handle_halt() repeating the check.) Change the definition of the method so that it returns a bool to tell cpu_handle_halt() whether to stay in halt or not. We will want this for the Arm target, where FEAT_WFxT wants to do some work only for the case where the CPU is in halt but about to leave it.

2024-05-24tcg/cputlb: remove other-cpu capability from TLB flushingNicholas Piggin
Some TLB flush operations can flush other CPUs. The problem with this is they used non-synced variants of flushes (i.e., that return before the destination has completed the flush). Since all TLB flush users need the _synced variants, and that last user (ppc) of the non-synced flush was buggy, this is a footgun waiting to go off. There do not seem to be any callers that flush other CPUs, so remove the capability. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
