skalk commented Feb 8, 2022

The re-newed lx_emul and lx_kit layers to support porting of Linux kernel drivers was written for ARM 64-bit initially. Now, that we want to use this new approach for all driver ports, we have to support other architectures as well.

lx_kit: move setjmp/longjmp away from legacy
e90e00b 
We use the architecture-specific setjmp/longjmp implementation without
modification in the newer lx_kit implementation as well. There is no
need for a duplication.

lx_emul: update to linux kernel 5.14 as default
7f7f3e1 
Until now, the lx_emul layer addressed a 5.11 Linux Kernel port,
now that we add new architectures it is better to update the default version
first. There are especially changes in the task_struct code,
and the signature of some functions in the paging subsystem changed.

lx_kit: add Platform session wrapper for x86
18a078f 
The x86 platform driver uses a different API than the one for ARM for
which the lx_kit glue code was designed. Since the x86 platform driver
will eventually adopt a similar interface we implement a wrapper that
encapsulates the old interface.

* The upstream Linux Kernel version is now 5.14, no need for task_struct quirk
* _alloc_pages_bulk, wake_q_add, wake_up_q are provided by common lx_emul
* Some pathes and compilation units in the common lx_emul have changed,
