<pre wrap="">Quoting the README:
...
If you build a custom kernel, note the following configuration items:
* CONFIG_CRC_CCITT must be enabled (y or m). On 2.6 kernels this
can be selected These can be selected from the "Library
Routines" submenu during kernel configuration via "make
menuconfig".

BTW: latest version is 1.4.12.1 .

<pre wrap="">The README says that RTC for ztdummy is supported on X86 kernels,
My ARM kernel does support RTC too so i can modify ztdummy.c to
support RTC
by adding an #ifdef.
Is there any further reasons that precludes usage of RTC on non-x86
platforms
Thanks
Vadim

<pre wrap=""><!---->Setting your kernel clock to 1000Hz will allow you to build it without
rtc getting involved

The question is what is the prefered solution performance-wise?<br>
RTC or HZ=1000<br>
