Subject: [PATCH v2 0/9] iOS and Apple Silicon host support
Date: Sun, 18 Oct 2020 18:39:19 -0700 [thread overview]
Message-ID: <20201019013928.72770-1-j@getutm.app> (raw)
These set of changes brings QEMU TCG to iOS devices and future Apple Silicon
devices. They were originally developed last year and have been working in the
UTM app. Recently, we ported the changes to master, re-wrote a lot of the build
script changes for meson, and broke up the patches into more distinct units.
A summary of the changes:
* `CONFIG_IOS` and `CONFIG_IOS_JIT` defined when building for iOS and
iOS specific changes (as well as unsupported code) are gated behind it.
* A new dependency, libucontext is added since iOS does not have native ucontext
and broken support for sigaltstack. libucontext is available as a new option
for coroutine backend.
* On stock iOS devices, there is a workaround for running JIT code without
any special entitlement. It requires the JIT region to be mirror mapped with
one region RW and another one RX. To support this style of JIT, TCG is changed
to support writing to a different code_ptr. These changes are gated by the
`CONFIG_IOS_JIT`.
* For (recent) jailbroken iOS devices as well as upcoming Apple Silicon devices,
there are new rules for applications supporting JIT (with the proper
entitlement). These rules are implemented as well.
Since v2:
* Changed getting mirror pointer from a macro to inline functions
* Split constification of TCG code pointers to separate patch
* Removed slirp updates (will send future patch once slirp changes are in)
* Removed shared library patch (will send future patch)
