2023-04-20tpm: Add support for TPM device over I2C busNinad Palsule4-0/+585
Qemu already supports devices attached to ISA and sysbus. This drop adds support for the I2C bus attached TPM devices. I2C model only supports TPM2 protocol. This commit includes changes for the common code. - Added I2C emulation model. Logic was added in the model to temporarily cache the data as I2C interface works per byte basis. - New tpm type "tpm-tis-i2c" added for I2C support. The user has to provide this string on command line. Testing: TPM I2C device module is tested using SWTPM (software based TPM package). Qemu uses the rainier machine and is connected to swtpm over the socket interface. The command to start swtpm is as follows: $ swtpm socket --tpmstate dir=/tmp/mytpm1 \ --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \ --tpm2 --log level=100 The command to start qemu is as follows: $ qemu-system-arm -M rainier-bmc -nographic \ -kernel ${IMAGEPATH}/fitImage-linux.bin \ -dtb ${IMAGEPATH}/aspeed-bmc-ibm-rainier.dtb \ -initrd ${IMAGEPATH}/obmc-phosphor-initramfs.rootfs.cpio.xz \ -drive file=${IMAGEPATH}/obmc-phosphor-image.rootfs.wic.qcow2,if=sd,index=2 \ -net nic -net user,hostfwd=:127.0.0.1:2222-:22,hostfwd=:127.0.0.1:2443-:443 \ -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis-i2c,tpmdev=tpm0,bus=aspeed.i2c.bus.12,address=0x2e Signed-off-by: Ninad Palsule <ninad@linux.ibm.com> Reviewed-by: Stefan Berger <stefanb@linux.ibm.com> Tested-by: Stefan Berger <stefanb@linux.ibm.com> Reviewed-by: Cédric Le Goater <clg@kaod.org> Reviewed-by: Joel Stanley <joel@jms.id.au> Tested-by: Joel Stanley <joel@jms.id.au> Message-id: 20230414220754.1191476-4-ninadpalsule@us.ibm.com
2023-04-20tpm: Extend common APIs to support TPM TIS I2CNinad Palsule2-8/+31
Qemu already supports devices attached to ISA and sysbus. This drop adds support for the I2C bus attached TPM devices. This commit includes changes for the common code. - Added support for the new checksum registers which are required for the I2C support. The checksum calculation is handled in the qemu common code. - Added wrapper function for read and write data so that I2C code can call it without MMIO interface. The TPM TIS I2C spec describes in the table in section "Interface Locality Usage per Register" that the TPM_INT_ENABLE and TPM_INT_STATUS registers must be writable for any locality even if the locality is not the active locality. Therefore, remove the checks whether the writing locality is the active locality for these registers.

2022-09-09tpm_crb: Avoid backend startup just before shutdown under XenRoss Lagerwall1-1/+6
When running under Xen and the guest reboots, it boots into a new domain with a new QEMU process (and a new swtpm process if using the emulator backend). The existing reset function is triggered just before the old QEMU process exists which causes QEMU to startup the TPM backend and then immediately shut it down. This is probably harmless but when using the emulated backend, it wastes CPU and IO time reloading state, etc. Fix this by calling the reset function directly from realize() when running under Xen. During a reboot, this will be called by the QEMU process for the new domain.

At the moment, there doesn't seems to be any way to know that QEMU made modification to the command buffer. This is potentially an issue on Xen while migrating a guest, as modification to the buffer after the migration as started could be ignored and not transfered to the destination.

2022-06-01hw/tpm/tpm_tis_common.c: Assert that locty is in rangePeter Maydell1-1/+6
In tpm_tis_mmio_read(), tpm_tis_mmio_write() and tpm_tis_dump_state(), we calculate a locality index with tpm_tis_locality_from_addr() and then use it as an index into the s->loc[] array. In all these cases, the array index can't overflow because the MemoryRegion is sized to be TPM_TIS_NUM_LOCALITIES << TPM_TIS_LOCALITY_SHIFT bytes. However, Coverity can't see that, and it complains (CID 1487138, 1487180, 1487188, 1487198, 1487240). Add an assertion to tpm_tis_locality_from_addr() that the calculated locality index is valid, which will help Coverity and also catch any potential future bug where the MemoryRegion isn't sized exactly.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini1-0/+1
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

We are going to make "tpm_util.h" publicly accessible by moving it to the include/ directory in the next commit. The DEFINE_PROP_TPMBE() macro is only meaningful for the TPM hardware files (in hw/tpm/), so keep this macro in a local header.

2020-06-19hw/tpm: Make TRACE_TPM_UTIL_SHOW_BUFFER check local to tpm_util.cPhilippe Mathieu-Daudé2-6/+5
The trace_event_get_state_backends() call is useful to avoid making extensive calls (usually preparing arguments passed to the tracing framework. In this case, the extensive work is done in tpm_util_show_buffer(), and the arguments used to call it don't involve extra processing. Simplify by moving the TRACE_TPM_UTIL_SHOW_BUFFER check to tpm_util_show_buffer.

As we plan to introduce a SysBus TPM TIS device, let's make the TPMState a common struct usable by both the ISADevice and the SysBusDevice. TPMStateISA embeds the struct and inherits from the ISADevice. The prototype of functions bound to be used by both the ISA and SysBus devices is changed to take TPMState handle. A bunch of structs also are renamed to be specialized for the ISA device. Besides those transformations, no functional change is expected.
