A TD runs +in a CPU mode that is designed to protect the confidentiality of its memory +contents and its CPU state from any other software, including the hosting +Virtual Machine Monitor (VMM), unless explicitly shared by the TD itself. + +Prerequisites +------------- + +To run TD, the physical machine needs to have TDX module loaded and initialized +while KVM hypervisor has TDX support and has TDX enabled. If those requirements +are met, the ``KVM_CAP_VM_TYPES`` will report the support of ``KVM_X86_TDX_VM``. + +Trust Domain Virtual Firmware (TDVF) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Trust Domain Virtual Firmware (TDVF) is required to provide TD services to boot +TD Guest OS. TDVF needs to be copied to guest private memory and measured before +the TD boots. + +KVM vcpu ioctl ``KVM_TDX_INIT_MEM_REGION`` can be used to populate the TDVF +content into its private memory. + +Since TDX doesn't support readonly memslot, TDVF cannot be mapped as pflash +device and it actually works as RAM. "-bios" option is chosen to load TDVF. + +OVMF is the opensource firmware that implements the TDVF support. Thus the +command line to specify and load TDVF is ``-bios OVMF.fd`` + +Feature Configuration +--------------------- + +Unlike non-TDX VM, the CPU features (enumerated by CPU or MSR) of a TD are not +under full control of VMM. VMM can only configure part of features of a TD on +``KVM_TDX_INIT_VM`` command of VM scope ``MEMORY_ENCRYPT_OP`` ioctl. + +The configurable features have three types: + +- Attributes: + - PKS (bit 30) controls whether Supervisor Protection Keys is exposed to TD, + which determines related CPUID bit and CR4 bit; + - PERFMON (bit 63) controls whether PMU is exposed to TD. + +- XSAVE related features (XFAM): + XFAM is a 64b mask, which has the same format as XCR0 or IA32_XSS MSR. It + determines the set of extended features available for use by the guest TD. + +- CPUID features: + Only some bits of some CPUID leaves are directly configurable by VMM. + +What features can be configured is reported via TDX capabilities. + +TDX capabilities +~~~~~~~~~~~~~~~~ + +The VM scope ``MEMORY_ENCRYPT_OP`` ioctl provides command ``KVM_TDX_CAPABILITIES`` +to get the TDX capabilities from KVM. It returns a data structure of +``struct kvm_tdx_capabilities``, which tells the supported configuration of +attributes, XFAM and CPUIDs. + +TD attributes +~~~~~~~~~~~~~ + +QEMU supports configuring raw 64-bit TD attributes directly via "attributes" +property of "tdx-guest" object. Note, it's users' responsibility to provide a +valid value because some bits may not supported by current QEMU or KVM yet. + +QEMU also supports the configuration of individual attribute bits that are +supported by it, via properties of "tdx-guest" object. +E.g., "sept-ve-disable" (bit 28). + +MSR based features +~~~~~~~~~~~~~~~~~~ + +Current KVM doesn't support MSR based feature (e.g., MSR_IA32_ARCH_CAPABILITIES) +configuration for TDX, and it's a future work to enable it in QEMU when KVM adds +support of it. + +Feature check +~~~~~~~~~~~~~ + +QEMU checks if the final (CPU) features, determined by given cpu model and +explicit feature adjustment of "+featureA/-featureB", can be supported or not. +It can produce feature not supported warning like + + "warning: host doesn't support requested feature: CPUID.07H:EBX.intel-pt [bit 25]" + +It can also produce warning like + + "warning: TDX forcibly sets the feature: CPUID.80000007H:EDX.invtsc [bit 8]" + +if the fixed-1 feature is requested to be disabled explicitly. This is newly +added to QEMU for TDX because TDX has fixed-1 features that are forcibly enabled +by TDX module and VMM cannot disable them. + +Launching a TD (TDX VM) +----------------------- + +To launch a TD, the necessary command line options are tdx-guest object and +split kernel-irqchip, as below: + +.. parsed-literal:: + + |qemu_system_x86| \\ + -accel kvm \\ + -cpu host \\ + -object tdx-guest,id=tdx0 \\ + -machine ...,confidential-guest-support=tdx0 \\ + -bios OVMF.fd \\ + +Restrictions +------------ + + - kernel-irqchip must be split; + + This is set by default for TDX guest if kernel-irqchip is left on its default + 'auto' setting. + + - No readonly support for private memory; + + - No SMM support: SMM support requires manipulating the guest register states + which is not allowed; + +Debugging +--------- + +Bit 0 of TD attributes, is DEBUG bit, which decides if the TD runs in off-TD +debug mode. When in off-TD debug mode, TD's VCPU state and private memory are +accessible via given SEAMCALLs. This requires KVM to expose APIs to invoke those +SEAMCALLs and corresonponding QEMU change. + +It's targeted as future work. + +TD attestation +-------------- + +In TD guest, the attestation process is used to verify the TDX guest +trustworthiness to other entities before provisioning secrets to the guest. + +TD attestation is initiated first by calling TDG.MR.REPORT inside TD to get the +REPORT. Then the REPORT data needs to be converted into a remotely verifiable +Quote by SGX Quoting Enclave (QE). + +It's a future work in QEMU to add support of TD attestation since it lacks +support in current KVM. + +Live Migration +-------------- + +Future work. + +References +---------- + +- `TDX Homepage <https://www.intel.com/content/www/us/en/developer/articles/technical/intel-trust-domain-extensions.html>`__ + +- `SGX QE <https://github.com/intel/SGXDataCenterAttestationPrimitives/tree/master/QuoteGeneration>`__ diff --git a/docs/system/target-i386.rst b/docs/system/target-i386.rst index ab7af1a..43b09c7 100644 --- a/docs/system/target-i386.rst +++ b/docs/system/target-i386.rst @@ -31,6 +31,7 @@ Architectural features i386/kvm-pv i386/sgx i386/amd-memory-encryption + i386/tdx OS requirements ~~~~~~~~~~~~~~~ diff --git a/gdbstub/meson.build b/gdbstub/meson.build index b25db86..15c666f 100644 --- a/gdbstub/meson.build +++ b/gdbstub/meson.build @@ -5,13 +5,13 @@ # # We build two versions of gdbstub, one for each mode -libuser_ss.add(files( +user_ss.add(files( 'gdbstub.c', 'syscalls.c', 'user.c' )) -libsystem_ss.add(files( +system_ss.add(files( 'gdbstub.c', 'syscalls.c', 'system.c' diff --git a/hw/arm/Kconfig b/hw/arm/Kconfig index a55b44d..f543d94 100644 --- a/hw/arm/Kconfig +++ b/hw/arm/Kconfig @@ -147,7 +147,6 @@ config OMAP bool select FRAMEBUFFER select I2C - select NAND select PFLASH_CFI01 select SD select SERIAL_MM diff --git a/hw/arm/boot.c b/hw/arm/boot.c index f94b940..79afb51 100644 --- a/hw/arm/boot.c +++ b/hw/arm/boot.c @@ -19,6 +19,7 @@ #include "system/kvm.h" #include "system/tcg.h" #include "system/system.h" +#include "system/memory.h" #include "system/numa.h" #include "hw/boards.h" #include "system/reset.h" diff --git a/hw/arm/meson.build b/hw/arm/meson.build index 5098795..d90be8f 100644 --- a/hw/arm/meson.build +++ b/hw/arm/meson.build @@ -8,7 +8,7 @@ arm_common_ss.add(when: 'CONFIG_HIGHBANK', if_true: files('highbank.c')) arm_common_ss.add(when: 'CONFIG_INTEGRATOR', if_true: files('integratorcp.c')) arm_common_ss.add(when: 'CONFIG_MICROBIT', if_true: files('microbit.c')) arm_common_ss.add(when: 'CONFIG_MPS3R', if_true: files('mps3r.c')) -arm_common_ss.add(when: 'CONFIG_MUSICPAL', if_true: [pixman, files('musicpal.c')]) +arm_common_ss.add(when: 'CONFIG_MUSICPAL', if_true: [files('musicpal.c')]) arm_common_ss.add(when: 'CONFIG_NETDUINOPLUS2', if_true: files('netduinoplus2.c')) arm_common_ss.add(when: 'CONFIG_OLIMEX_STM32_H405', if_true: files('olimex-stm32-h405.c')) arm_common_ss.add(when: 'CONFIG_NPCM7XX', if_true: files('npcm7xx.c', 'npcm7xx_boards.c')) @@ -79,7 +79,7 @@ arm_common_ss.add(when: 'CONFIG_SX1', if_true: files('omap_sx1.c')) arm_common_ss.add(when: 'CONFIG_VERSATILE', if_true: files('versatilepb.c')) arm_common_ss.add(when: 'CONFIG_VEXPRESS', if_true: files('vexpress.c')) -arm_common_ss.add(fdt, files('boot.c')) +arm_common_ss.add(files('boot.c')) hw_arch += {'arm': arm_ss} hw_common_arch += {'arm': arm_common_ss} diff --git a/hw/arm/npcm8xx.c b/hw/arm/npcm8xx.c index d7ee306..a276fea 100644 --- a/hw/arm/npcm8xx.c +++ b/hw/arm/npcm8xx.c @@ -67,6 +67,9 @@ /* SDHCI Modules */ #define NPCM8XX_MMC_BA 0xf0842000 +/* PCS Module */ +#define NPCM8XX_PCS_BA 0xf0780000 + /* PSPI Modules */ #define NPCM8XX_PSPI_BA 0xf0201000 @@ -85,6 +88,10 @@ enum NPCM8xxInterrupt { NPCM8XX_ADC_IRQ = 0, NPCM8XX_PECI_IRQ = 6, NPCM8XX_KCS_HIB_IRQ = 9, + NPCM8XX_GMAC1_IRQ = 14, + NPCM8XX_GMAC2_IRQ, + NPCM8XX_GMAC3_IRQ, + NPCM8XX_GMAC4_IRQ, NPCM8XX_MMC_IRQ = 26, NPCM8XX_PSPI_IRQ = 28, NPCM8XX_TIMER0_IRQ = 32, /* Timer Module 0 */ @@ -260,6 +267,14 @@ static const hwaddr npcm8xx_smbus_addr[] = { 0xfff0a000, }; +/* Register base address for each GMAC Module */ +static const hwaddr npcm8xx_gmac_addr[] = { + 0xf0802000, + 0xf0804000, + 0xf0806000, + 0xf0808000, +}; + /* Register base address for each USB host EHCI registers */ static const hwaddr npcm8xx_ehci_addr[] = { 0xf0828100, @@ -350,6 +365,7 @@ static struct arm_boot_info npcm8xx_binfo = { .secure_boot = false, .board_id = -1, .board_setup_addr = NPCM8XX_BOARD_SETUP_ADDR, + .psci_conduit = QEMU_PSCI_CONDUIT_SMC, }; void npcm8xx_load_kernel(MachineState *machine, NPCM8xxState *soc) @@ -444,6 +460,11 @@ static void npcm8xx_init(Object *obj) object_initialize_child(obj, "mft[*]", &s->mft[i], TYPE_NPCM7XX_MFT); } + for (i = 0; i < ARRAY_SIZE(s->gmac); i++) { + object_initialize_child(obj, "gmac[*]", &s->gmac[i], TYPE_NPCM_GMAC); + } + object_initialize_child(obj, "pcs", &s->pcs, TYPE_NPCM_PCS); + object_initialize_child(obj, "mmc", &s->mmc, TYPE_NPCM7XX_SDHCI); object_initialize_child(obj, "pspi", &s->pspi, TYPE_NPCM_PSPI); } @@ -669,6 +690,35 @@ static void npcm8xx_realize(DeviceState *dev, Error **errp) } /* + * GMAC Modules.
