2023-07-10hw/riscv/virt: Restrict ACLINT to TCGPhilippe Mathieu-Daudé
The Advanced Core Local Interruptor (ACLINT) device can only be used with TCG. Check for TCG enabled instead of KVM being not. Only add the property when TCG is used.

2022-04-29hw/riscv: Enable TPM backendsAlistair Francis
Imply the TPM sysbus devices. This allows users to add TPM devices to the RISC-V virt board. This was tested by first creating an emulated TPM device: swtpm socket --tpm2 -t -d --tpmstate dir=/tmp/tpm \ --ctrl type=unixio,path=swtpm-sock Then launching QEMU with: -chardev socket,id=chrtpm,path=swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis-device,tpmdev=tpm0 The TPM device can be seen in the memory tree and the generated device tree.

2021-08-02docs: Format literals correctlyPeter Maydell
In rST markup, single backticks `like this` represent "interpreted text", which can be handled as a bunch of different things if tagged with a specific "role": https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#interpreted-text (the most common one for us is "reference to a URL, which gets hyperlinked"). The default "role" if none is specified is "title_reference", intended for references to book or article titles, and it renders into the HTML as <cite>...</cite> (usually comes out as italics). This commit fixes various places in the manual which were using single backticks when double backticks (for literal text) were intended, and covers those files where only one or two instances of these errors were made.
