[dev][sdmmc] use BTI This is a re-land of I1cb6db88c8a08c88c0de811acdb8123936fc9ffa (git 5a04ac31d589785303c0f41913fd59dbd5ad46ef), which was reverted in 335c3a414e169804eb9050d784af6cebd0f5c77f. Testing on Acer and Paradise showed no issue. The cause of the revert was this change making an existing buffer overrrun in the SDMMC driver become more visible (ZX-1851). The only changes are additional logging in error cases. Change-Id: Ia078bf659793983fc9240b0de1355e1d4d4d5c7c
Zircon is the core platform that powers the Fuchsia OS. Zircon is composed of a microkernel (source in kernel/...) as well as a small set of userspace services, drivers, and libraries (source in system/...) necessary for the system to boot, talk to hardware, load userspace processes and run them, etc. Fuchsia builds a much larger OS on top of this foundation.
The canonical Zircon Git repository is located at: https://fuchsia.googlesource.com/zircon
A read-only mirror of the code is present at: https://github.com/fuchsia-mirror/zircon
The Zircon Kernel provides syscalls to manage processes, threads, virtual memory, inter-process communication, waiting on object state changes, and locking (via futexes).
Currently there are some temporary syscalls that have been used for early bringup work, which will be going away in the future as the long term syscall API/ABI surface is finalized. The expectation is that there will be about 100 syscalls.
Zircon syscalls are generally non-blocking. The wait_one, wait_many port_wait and thread sleep being the notable exceptions.
