This change does not allow us to "run" these targets on + OpenBSD +* Fix linker scripts with TLS (Thread Local Storage) sections + (@palainp, @hannesm, @dinosaure, #542) +* Export TLS symbols (@palainp, @hannesm, @dinosaure, #546) + **breaking change** due to #542 & #546, tenders must be **upgraded**. Indeed, + solo5.0.7.* tenders will not be able to load correctly unikernels compiled + with solo5.0.8.0. + + This version implements Thread Local Storage. The user can initialise a TLS + block with `solo5_tls_init` on a pointer to `solo5_tls_size()` free bytes. + Then, the user is able to set the `tp` (Thread Pointer) pointer via + `solo5_set_tls_base(solo5_tls_tp_offset(tls_block))`. More details are + available into `solo5.h`. + + Note: this change does not allow a Solo5 unikernel to use multiple cores! It + only provides an API required by OCaml 5 / pthread to launch, at most, one + thread. +* Fix tests reported by NixOS (@greydot, @ehmry, #547) +* Split out the `time.c` implementation between Muen and HVT + (@dinosaure, @Kensan, #552) +* User hypercall instead of TSC-based clock when the user asks for the + wall-clock (@dinosaure, @reynir, #549, #550) + + Note: only hvt & virtio are updated to avoid a clock drift on the wall-clock. + Indeed, when the unikernel is suspended, the wall-clock is not updated. Muen + & Xen still use a TSC-based wall-clock. The spt target was already in sync + with the host's wall-clock. +* Improve the muen clock (@Kensan, #553) +* Fix the `.bss` section according to #542 & #546. The `.bss` section is tagged + with `PT_LOAD`. Tenders are available to load this section properly. + (@Kensan, @dinosaure, #551, #554) +* Fix the cross-compilation of Solo5 for `aarch64` + (@dinosaure, @palainp, @hannes, #555) + ## v0.7.5 (2022-12-07) * Since MirageOS moved from PV mode to PVH on Xen, and thus replacing Mini-OS
