| * | | hw/isa/vt82c686: Instantiate USB functions in host deviceBernhard Beschow2022-10-313-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB functions can be enabled/disabled through the ISA function. Also its interrupt routing can be influenced there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IDE function is closely tied to the ISA function (e.g. the IDE interrupt routing happens there), so it makes sense that the IDE function is instantiated within the south bridge itself.

It also has a lot of performance optimizations in the PowerPC emulation done by the researchers of the Eldorado institute. Between using gvec for VMX/VSX instructions, a full rework of the interrupt model and PMU optimizations, they managed to drastically speed up the emulation of powernv8/9/10 machines. Here's an example with avocado tests: - with master: tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8: PASS (38.89 s) tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9: PASS (43.89 s) - with this queue applied: tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8: PASS (21.23 s) tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9: PASS (22.58 s) Other ppc machines, like pseries, also had a noticeable performance boost. # -----BEGIN PGP SIGNATURE----- # # iHUEABYKAB0WIQQX6/+ZI9AYAK8oOBk82cqW3gMxZAUCY10J/gAKCRA82cqW3gMx # ZAbjAPwKNbE1wE2POJbMALBQAM5MewwLMV/UKGjE6jA7HAbb/AEA9e3o11FoUmSJ # rZkmTvMzBQZ81mMGRlS0cnqbrr4ADgc= # =gnKY # -----END PGP SIGNATURE----- # gpg: Signature made Sat 29 Oct 2022 07:09:50 EDT # gpg: using EDDSA key 17EBFF9923D01800AF2838193CD9CA96DE033164 # gpg: Good signature from "Daniel Henrique Barboza <danielhb413@gmail.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 17EB FF99 23D0 1800 AF28 3819 3CD9 CA96 DE03 3164 * tag 'pull-ppc-20221029' of https://gitlab.com/danielhb/qemu: (63 commits) target/ppc: Fix regression in Radix MMU hw/ppc/e500: Implement pflash handling hw/sd/sdhci: Rename ESDHC_* defines to USDHC_* hw/sd/sdhci-internal: Unexport ESDHC defines hw/block/pflash_cfi0{1, 2}: Error out if device length isn't a power of two docs/system/ppc/ppce500: Use qemu-system-ppc64 across the board(s) target/ppc: Increment PMC5 with inline insns target/ppc: Add new PMC HFLAGS ppc4xx_sdram: Add errp parameter to ppc4xx_sdram_banks() ppc4xx_sdram: Convert DDR SDRAM controller to new bank handling ppc4xx_sdram: Generalise bank setup ppc4xx_sdram: Rename local state variable for brevity ppc4xx_sdram: Use hwaddr for memory bank size ppc4xx_sdram: Move ppc4xx_sdram_banks() to ppc4xx_sdram.c ppc4xx_devs.c: Move DDR SDRAM controller model to ppc4xx_sdram.c ppc440_uc.c: Move DDR2 SDRAM controller model to ppc4xx_sdram.c target/ppc: move the p*_interrupt_powersave methods to excp_helper.c target/ppc: unify cpu->has_work based on cs->interrupt_request target/ppc: introduce ppc_maybe_interrupt target/ppc: remove ppc_store_lpcr from CONFIG_USER_ONLY builds ...

When guest_visible is false, it must not raise an exception, even if the radix configuration is not valid. This regression prevented Linux boot in a nested environment with L1 using TCG and emulating KVM (cap-nested-hv=on) and L2 using KVM. L2 would hang on Linux's futex_init(), when it tested how a futex_atomic_cmpxchg_inatomic() handled a fault, because L1 would start a loop of trying to perform partition scoped translations and raising exceptions.
