2023-05-05target/riscv: introduce riscv_cpu_add_misa_properties()Daniel Henrique Barboza1-0/+65
Ever since RISCVCPUConfig got introduced users are able to set CPU extensions in the command line. User settings are reflected in the cpu->cfg object for later use. These properties are used in the target/riscv/cpu.c code, most notably in riscv_cpu_validate_set_extensions(), where most of our realize time validations are made. And then there's env->misa_ext, the field where the MISA extensions are set, that is read everywhere else. We need to keep env->misa_ext updated with cpu->cfg settings, since our validations rely on it, forcing us to make register_cpu_props() write cpu->cfg.ext_N flags to cover for named CPUs that aren't used named properties but also needs to go through the same validation steps. Failing to so will make those name CPUs fail validation (see c66ffcd5358b for more info). Not only that, but we also need to sync env->misa_ext with cpu->cfg again during realize() time to catch any change the user might have done, since the rest of the code relies on that. Making cpu->cfg.ext_N and env->misa_ext reflect each other is not needed. What we want is a way for users to enable/disable MISA extensions, and there's nothing stopping us from letting the user write env->misa_ext directly. Here are the artifacts that will enable us to do that: - RISCVCPUMisaExtConfig will declare each MISA property; - cpu_set_misa_ext_cfg() is the setter for each property. We'll write env->misa_ext and env->misa_ext_mask with the appropriate misa_bit; cutting off cpu->cfg.ext_N from the logic; - cpu_get_misa_ext_cfg() is a getter that will retrieve the current val of the property based on env->misa_ext; - riscv_cpu_add_misa_properties() will be called in register_cpu_props() to init all MISA properties from the misa_ext_cfgs[] array. With this infrastructure we'll start to get rid of each cpu->cfg.ext_N attribute in the next patches.

2023-05-05target/riscv: remove MISA properties from isa_edata_arr[]Daniel Henrique Barboza1-2/+17
The code that disables extensions if there's a priv version mismatch uses cpu->cfg.ext_N properties to do its job. We're aiming to not rely on cpu->cfg.ext_N props for MISA bits. Split the MISA related verifications in a new function, removing it from isa_edata_arr[]. We're also erroring it out instead of disabling, making the cpu_init() function responsible for running an adequate priv spec for the MISA extensions it wants to use. Note that the RVV verification is being ignored since we're always have at least PRIV_VERSION_1_10_0.

2023-05-05target/riscv: sync env->misa_ext* with cpu->cfg in realize()Daniel Henrique Barboza1-38/+56
When riscv_cpu_realize() starts we're guaranteed to have cpu->cfg.ext_N properties updated. The same can't be said about env->misa_ext*, since the user might enable/disable MISA extensions in the command line, and env->misa_ext* won't caught these changes. The current solution is to sync everything at the end of validate_set_extensions(), checking every cpu->cfg.ext_N value to do a set_misa() in the end. The last change we're making in the MISA cfg flags are in the G extension logic, enabling IMAFG if cpu->cfg_ext.g is enabled. Otherwise we're not making any changes in MISA bits ever since realize() starts. There's no reason to postpone misa_ext updates until the end of the validation. Let's do it earlier, during realize(), in a new helper called riscv_cpu_sync_misa_cfg(). If cpu->cfg.ext_g is enabled, do it again by updating env->misa_ext* directly. This is a pre-requisite to allow riscv_cpu_validate_set_extensions() to use riscv_has_ext() instead of cpu->cfg.ext_N to validate the MISA extensions, which is our end goal here.

Point XVentanaCondOps to the (newly implemented) Zicond implementation to reduce the future maintenance burden. Also updating MAINTAINERS as trans_xventanacondops.c.inc.

2023-05-05target/riscv: refactor Zicond supportPhilipp Tomsich1-15/+21
After the original Zicond support was stuck/fell through the cracks on the mailing list at v3 (and a different implementation was merged in the meanwhile), we need to refactor Zicond to prepare it to be reused by XVentanaCondOps. This commit lifts the common logic out into gen_czero and uses this via gen_logic and 2 helper functions (effectively partial closures).
