This RFC series introduces a KVM host "custom" model. Since v6.7 kernel, KVM/arm allows the userspace to overwrite the values of a subset of ID regs. The list of writable fields continues to grow. The feature ID range is defined as the AArch64 System register space with op0==3, op1=={0, 1, 3}, CRn==0, CRm=={0-7}, op2=={0-7}. The custom model uses this capability and allows to tune the host passthrough model by overriding some of the host passthrough ID regs. The end goal is to get more flexibility when migrating guests between different machines. We would like the upper software layer to be able detect how tunable the vpcu is on both source and destination and accordingly define a customized KVM host model that can fit both ends. With the legacy host passthrough model, this migration use case would fail. QEMU queries the host kernel to get the list of writable ID reg fields and expose all the writable fields as uint64 properties. Those are named "SYSREG_<REG>_<FIELD>". REG and FIELD names are those described in ARM ARM Reference manual and linux arch/arm64/tools/sysreg. Some awk scriptsintroduced in the series help parsing the sysreg file and generate some code. those scripts are used in a similar way as scripts/update-linux-headers.sh. In case the ABI gets broken, it is still possible to manually edit the generated code. However it is globally expected the REG and FIELD names are stable. The list of SYSREG_ID properties can be retrieved through the qmp monitor using query-cpu-model-expansion [2]. The first part of the series mostly consists in migrating id reg storage from named fields in ARMISARegisters to anonymous index ordered storage in an IdRegMap struct array. The goal is to have a generic way to store all id registers, also compatible with the way we retrieve their writable capability at kernel level through the KVM_ARM_GET_REG_WRITABLE_MASKS ioctl. Having named fields prevented us from getting this scalability/genericity. Although the change is invasive it is quite straightforward and should be easy to be reviewed. Then the bulk of the job is to retrieve the writable ID fields and match them against a "human readable" description of those fields. We use awk scripts, derived from kernel arch/arm64/tools/gen-sysreg.awk (so all the credit to Mark Rutland) that populates a data structure which describes all the ID regs in sysreg and their fields. We match writable ID reg fields with those latter and dynamically create a uint64 property. Then we need to extend the list of id regs read from the host so that we get a chance to let their value overriden and write them back into KVM . This expectation is that this custom KVM host model can prepare for the advent of named models. Introducing named models with reduced and explicitly defined features is the next step. Obviously this series is not able to cope with non writable ID regs. For instance the problematic of MIDR/REVIDR setting is not handled at the moment. Connie & Eric This series can be found at: https://github.com/eauger/qemu/tree/custom-cpu-model-rfc TESTS: - with few IDREG fields that can be easily examined from guest userspace: -cpu custom,SYSREG_ID_AA64ISAR0_EL1_DP=0x0,SYSREG_ID_AA64ISAR1_EL1_DPB=0x0 - migration between custom models - TCG A57 non regressions. Light testing for TCG though. Deep review may detect some mistakes when migrating between named fields and IDRegMap storage - light testing of introspection. Testing a given writable ID field value with query-cpu-model-expansion is not supported yet. TODO/QUESTIONS: - Some idreg named fields are not yet migrated to an array storage. some of them are not in isar struct either. Maybe we could have handled TCG and KVM separately and it may turn out that this conversion is unneeded. So as it is quite cumbersome I prefered to keep it for a later stage. - the custom model does not come with legacy host properties such as SVE, MTE, expecially those that induce some KVM settings. This needs to be fixed. - The custom model and its exposed properties depend on the host capabilities. More and more IDREG become writable meaning that the custom model gains more properties over the time and it is host linux dependent. At the moment there is no versioning in place. By default the custom model is a host passthrough model (besides the legacy functions). So if the end-user tries to set a field that is not writable from a kernel pov, it will fail. Nevertheless a versionned custom model could constrain the props exposed, independently on the host linux capabilities. - the QEMU layer does not take care of IDREG field value consistency. The kernel neither. I imagine this could be the role of the upper layer to implement a vcpu profile that makes sure settings are consistent. Here we come to "named" models. What should they look like on ARM? - Implementation details: - it seems there are a lot of duplications in the code. ID regs are described in different manners, with different data structs, for TCG, now for KVM. - The IdRegMap->regs is sparsely populated. Maybe a better data struct could be used, although this is the one chosen for the kernel uapi.

In this description we only care about non RES/RAZ fields, ie. named fields. The registers are populated in a 3x8x8 array and their fields are added in a sorted list.

As we want to introduce properties for all writable ID reg fields, we want more genericity and read more default host register values. Introduce a new get_host_cpu_idregs() helper and add a new exhaustive boolean parameter to kvm_arm_get_host_cpu_features() and kvm_arm_set_cpu_features_from_host() to select the right behavior. the host cpu model keeps the legacy behavior while the new custom model will read the legacy regs plus all the writable ones. This definitively brings some redundancy. A writable_map IdRegMap is introduced in the CPU object. A subsequent patch will populate it.

Also available at gitlab.com/cohuck/qemu arm-cpu-model-rfcv2 Find Eric's original cover letter below, so that I do not need to repeat myself on the aspects that have not changed since RFCv1 :) Changes from RFCv1: Rebased on more recent QEMU (some adaptions in the register conversions of the first few patches.) Based on feedback, I have removed the "custom" cpu model; instead, I have added the new SYSREG_<REG>_<FIELD> properties to the "host" model. This works well if you want to tweak anything that does not correspond to the existing properties for the host model; however, if you e.g. wanted to tweak sve, you have two ways to do so -- we'd probably either want to check for conflicts, or just declare precedence. The kvm-specific props remain unchanged, as they are orthogonal to this configuration. The cpu model expansion for the "host" model now dumps the new SYSREG_ properties in addition to the existing host model properties; this is a bit ugly, but I don't see a good way on how to split this up. Some more adaptions due to the removal of the "custom" model. Things *not* changed from RFCv1: SYSREG_ property naming (can be tweaked easily, once we are clear on what the interface should look like.) Sysreg generation scripts, and the generated files (I have not updated anything there.) I think generating the various definitions makes sense, as long as we double-check the generated files on each update (which would be something to trigger manually anyway.) What I would like us to reach some kind of consensus on: How to continue with the patches moving the ID registers from the isar struct into the idregs array. These are a bit of churn to drag along; if they make sense, maybe they can be picked independently of this series? Whether it make sense to continue with the approach of tweaking values in the ID registers in general. If we want to be able to migrate between cpus that do not differ wildly, we'll encounter differences that cannot be expressed via FEAT_xxx -- e.g. when comparing various AmpereAltra Max systems, they only differ in parts of CTR_EL0 -- which is not a feature register, but a writable register. Please take a look, and looking forward to your feedback :) *********************************************************************** Title: Introduce a customizable aarch64 KVM host model This RFC series introduces a KVM host "custom" model. Since v6.7 kernel, KVM/arm allows the userspace to overwrite the values of a subset of ID regs. The list of writable fields continues to grow. The feature ID range is defined as the AArch64 System register space with op0==3, op1=={0, 1, 3}, CRn==0, CRm=={0-7}, op2=={0-7}. The custom model uses this capability and allows to tune the host passthrough model by overriding some of the host passthrough ID regs. The end goal is to get more flexibility when migrating guests between different machines. We would like the upper software layer to be able detect how tunable the vpcu is on both source and destination and accordingly define a customized KVM host model that can fit both ends. With the legacy host passthrough model, this migration use case would fail. QEMU queries the host kernel to get the list of writable ID reg fields and expose all the writable fields as uint64 properties. Those are named "SYSREG_<REG>_<FIELD>". REG and FIELD names are those described in ARM ARM Reference manual and linux arch/arm64/tools/sysreg. Some awk scriptsintroduced in the series help parsing the sysreg file and generate some code. those scripts are used in a similar way as scripts/update-linux-headers.sh. In case the ABI gets broken, it is still possible to manually edit the generated code. However it is globally expected the REG and FIELD names are stable. The list of SYSREG_ID properties can be retrieved through the qmp monitor using query-cpu-model-expansion [2]. The first part of the series mostly consists in migrating id reg storage from named fields in ARMISARegisters to anonymous index ordered storage in an IdRegMap struct array. The goal is to have a generic way to store all id registers, also compatible with the way we retrieve their writable capability at kernel level through the KVM_ARM_GET_REG_WRITABLE_MASKS ioctl. Having named fields prevented us from getting this scalability/genericity. Although the change is invasive it is quite straightforward and should be easy to be reviewed. Then the bulk of the job is to retrieve the writable ID fields and match them against a "human readable" description of those fields. We use awk scripts, derived from kernel arch/arm64/tools/gen-sysreg.awk (so all the credit to Mark Rutland) that populates a data structure which describes all the ID regs in sysreg and their fields. We match writable ID reg fields with those latter and dynamically create a uint64 property. Then we need to extend the list of id regs read from the host so that we get a chance to let their value overriden and write them back into KVM . This expectation is that this custom KVM host model can prepare for the advent of named models. Introducing named models with reduced and explicitly defined features is the next step. Obviously this series is not able to cope with non writable ID regs. For instance the problematic of MIDR/REVIDR setting is not handled at the moment. TESTS: - with few IDREG fields that can be easily examined from guest userspace: -cpu custom,SYSREG_ID_AA64ISAR0_EL1_DP=0x0,SYSREG_ID_AA64ISAR1_EL1_DPB=0x0 - migration between custom models - TCG A57 non regressions. Light testing for TCG though. Deep review may detect some mistakes when migrating between named fields and IDRegMap storage - light testing of introspection. Testing a given writable ID field value with query-cpu-model-expansion is not supported yet. TODO/QUESTIONS: - Some idreg named fields are not yet migrated to an array storage. some of them are not in isar struct either. Maybe we could have handled TCG and KVM separately and it may turn out that this conversion is unneeded. So as it is quite cumbersome I prefered to keep it for a later stage. - the custom model does not come with legacy host properties such as SVE, MTE, expecially those that induce some KVM settings. This needs to be fixed. - The custom model and its exposed properties depend on the host capabilities. More and more IDREG become writable meaning that the custom model gains more properties over the time and it is host linux dependent. At the moment there is no versioning in place. By default the custom model is a host passthrough model (besides the legacy functions). So if the end-user tries to set a field that is not writable from a kernel pov, it will fail. Nevertheless a versionned custom model could constrain the props exposed, independently on the host linux capabilities. - the QEMU layer does not take care of IDREG field value consistency. The kernel neither. I imagine this could be the role of the upper layer to implement a vcpu profile that makes sure settings are consistent. Here we come to "named" models. What should they look like on ARM? - Implementation details: - it seems there are a lot of duplications in the code. ID regs are described in different manners, with different data structs, for TCG, now for KVM. - The IdRegMap->regs is sparsely populated. Maybe a better data struct could be used, although this is the one chosen for the kernel uapi.

That code will be automatically generated from linux arch/arm64/tools/sysreg. For the time being let's just describe a single id reg, CTR_EL0. In this description we only care about non RES/RAZ fields, ie. named fields. The registers are populated in a 3x8x8 array and their fields are added in a sorted list.

Invocation of ./update-aarch64-sysreg-code.sh $PATH_TO_LINUX_SOURCE_TREE in scripts directory do generate 2 qemu files: - target/arm/cpu-sysreg-properties.c - target/arm/cpu-sysregs.h cpu-sysregs.h creates defined for all system registers. However cpu-sysreg-properties.c only cares about feature ID registers. update-aarch64-sysreg-code.sh calls two awk scripts. gen-cpu-sysreg-properties.awk is inherited from kernel arch/arm64/tools/gen-sysreg.awk.

<eric.auger@redhat.com> At the moment kvm_arm_get_host_cpu_features() reads a subset of the ID regs. As we want to introduce properties for all writable ID reg fields, we want more genericity and read more default host register values. Introduce a new get_host_cpu_idregs() helper and add a new exhaustive boolean parameter to kvm_arm_get_host_cpu_features() and kvm_arm_set_cpu_features_from_host() to select the right behavior. The host cpu model will keep the legacy behavior unless the writable id register interface is available. A writable_map IdRegMap is introduced in the CPU object. A subsequent patch will populate it.
