This is clarified in [1]. [2] is a bug tracker asking for the profile spec to be less cryptic about it. As far as QEMU goes we understand extensions as something that the user can enable/disable in the command line. This isn't the case for named features, so we'll have to reach a middle ground. We'll keep our existing nomenclature 'named features' to refer to any extension that the user can't control in the command line. We'll also do the following: - 'svade' and 'zic64b' flags are renamed to 'ext_svade' and 'ext_zic64b'. 'ext_svade' and 'ext_zic64b' now have riscv,isa strings and priv_spec versions; - skip name feature check in cpu_bump_multi_ext_priv_ver(). Now that named features have a riscv,isa and an entry in isa_edata_arr[] we don't need to gate the call to cpu_cfg_ext_get_min_version() anymore.

We can't do this anymore since named features also has a riscv,isa entry. Let's add them to riscv_cpu_named_features[]. They will also need to be explicitly enabled in both profile descriptions. TCG will enable the named features it already implements, other accelerators are free to handle it as they like. After this patch, here's the riscv,isa from a buildroot using the 'rva22s64' CPU: # cat /proc/device-tree/cpus/cpu@0/riscv,isa rv64imafdc_zic64b_zicbom_zicbop_zicboz_ziccamoa_ziccif_zicclsm_ziccrse_ zicntr_zicsr_zifencei_zihintpause_zihpm_za64rs_zfhmin_zca_zcd_zba_zbb_ zbs_zkt_sscounterenw_sstvala_sstvecd_svade_svinval_svpbmt# Signed-off-by: Daniel Henrique Barboza --- target/riscv/cpu.c | 41 +++++++++++++++++++++++++++++--------- target/riscv/cpu_cfg.h | 9 +++++++++ target/riscv/tcg/tcg-cpu.c | 19 +++++++++++++++++- 3 files changed, 59 insertions(+), 10 deletions(-) diff --git a/target/riscv/cpu.c b/target/riscv/cpu.c index 28d3cfa8ce..1ecd8a57ed 100644 --- a/target/riscv/cpu.c +++ b/target/riscv/cpu.c @@ -101,6 +101,10 @@ const RISCVIsaExtData isa_edata_arr[] =3D { ISA_EXT_DATA_ENTRY(zicbom, PRIV_VERSION_1_12_0, ext_zicbom), ISA_EXT_DATA_ENTRY(zicbop, PRIV_VERSION_1_12_0, ext_zicbop), ISA_EXT_DATA_ENTRY(zicboz, PRIV_VERSION_1_12_0, ext_zicboz), + ISA_EXT_DATA_ENTRY(ziccamoa, PRIV_VERSION_1_11_0, ext_ziccamoa), + ISA_EXT_DATA_ENTRY(ziccif, PRIV_VERSION_1_11_0, ext_ziccif), + ISA_EXT_DATA_ENTRY(zicclsm, PRIV_VERSION_1_11_0, ext_zicclsm), + ISA_EXT_DATA_ENTRY(ziccrse, PRIV_VERSION_1_11_0, ext_ziccrse), ISA_EXT_DATA_ENTRY(zicond, PRIV_VERSION_1_12_0, ext_zicond), ISA_EXT_DATA_ENTRY(zicntr, PRIV_VERSION_1_12_0, ext_zicntr), ISA_EXT_DATA_ENTRY(zicsr, PRIV_VERSION_1_10_0, ext_zicsr), @@ -109,6 +113,7 @@ const RISCVIsaExtData isa_edata_arr[] =3D { ISA_EXT_DATA_ENTRY(zihintpause, PRIV_VERSION_1_10_0, ext_zihintpause), ISA_EXT_DATA_ENTRY(zihpm, PRIV_VERSION_1_12_0, ext_zihpm), ISA_EXT_DATA_ENTRY(zmmul, PRIV_VERSION_1_12_0, ext_zmmul), + ISA_EXT_DATA_ENTRY(za64rs, PRIV_VERSION_1_12_0, ext_za64rs), ISA_EXT_DATA_ENTRY(zacas, PRIV_VERSION_1_12_0, ext_zacas), ISA_EXT_DATA_ENTRY(zawrs, PRIV_VERSION_1_12_0, ext_zawrs), ISA_EXT_DATA_ENTRY(zfa, PRIV_VERSION_1_12_0, ext_zfa), @@ -170,8 +175,12 @@ const RISCVIsaExtData isa_edata_arr[] =3D { ISA_EXT_DATA_ENTRY(smepmp, PRIV_VERSION_1_12_0, ext_smepmp), ISA_EXT_DATA_ENTRY(smstateen, PRIV_VERSION_1_12_0, ext_smstateen), ISA_EXT_DATA_ENTRY(ssaia, PRIV_VERSION_1_12_0, ext_ssaia), + ISA_EXT_DATA_ENTRY(ssccptr, PRIV_VERSION_1_11_0, ext_ssccptr), ISA_EXT_DATA_ENTRY(sscofpmf, PRIV_VERSION_1_12_0, ext_sscofpmf), + ISA_EXT_DATA_ENTRY(sscounterenw, PRIV_VERSION_1_12_0, ext_sscounterenw= ), ISA_EXT_DATA_ENTRY(sstc, PRIV_VERSION_1_12_0, ext_sstc), + ISA_EXT_DATA_ENTRY(sstvala, PRIV_VERSION_1_12_0, ext_sstvala), + ISA_EXT_DATA_ENTRY(sstvecd, PRIV_VERSION_1_12_0, ext_sstvecd), ISA_EXT_DATA_ENTRY(svade, PRIV_VERSION_1_11_0, ext_svade), ISA_EXT_DATA_ENTRY(svadu, PRIV_VERSION_1_12_0, ext_svadu), ISA_EXT_DATA_ENTRY(svinval, PRIV_VERSION_1_12_0, ext_svinval), @@ -1523,6 +1532,22 @@ const RISCVCPUMultiExtConfig riscv_cpu_named_feature= s[] =3D { MULTI_EXT_CFG_BOOL("svade", ext_svade, true), MULTI_EXT_CFG_BOOL("zic64b", ext_zic64b, true), =20 + /* + * cache-related extensions that are always enabled + * since QEMU RISC-V does not have a cache model. + */ + MULTI_EXT_CFG_BOOL("za64rs", ext_za64rs, true), + MULTI_EXT_CFG_BOOL("ziccif", ext_ziccif, true), + MULTI_EXT_CFG_BOOL("ziccrse", ext_ziccrse, true), + MULTI_EXT_CFG_BOOL("ziccamoa", ext_ziccamoa, true), + MULTI_EXT_CFG_BOOL("zicclsm", ext_zicclsm, true), + MULTI_EXT_CFG_BOOL("ssccptr", ext_ssccptr, true), + + /* Other named features that QEMU TCG always implements */ + MULTI_EXT_CFG_BOOL("sstvecd", ext_sstvecd, true), + MULTI_EXT_CFG_BOOL("sstvala", ext_sstvala, true), + MULTI_EXT_CFG_BOOL("sscounterenw", ext_sscounterenw, true), + DEFINE_PROP_END_OF_LIST(), }; =20 @@ -2116,13 +2141,8 @@ static const PropertyInfo prop_marchid =3D { }; =20 /* - * RVA22U64 defines some 'named features' or 'synthetic extensions' - * that are cache related: Za64rs, Zic64b, Ziccif, Ziccrse, Ziccamoa - * and Zicclsm.

However, svade is an extension which makes sense for users to control, so treat it like a "normal" extension. The default is false, since QEMU has always implemented hardware A/D PTE bit updating, so users must opt into svade (or get it from a CPU type which enables it by default).
