The Butler public binary depends on libcurl3, which is no longer available for Ubuntu 20.04 and others. It should be re-compiled with libcurl4 support and re-released.

From here:
https://bitbucket.org/MergingTechnologies/ravenna-alsa-lkm/src/master/
I see there are some recent updates

Cannot compile it in kernel 6.2. Tried with gcc 12.2.1-5 and also with clang 15.0.7-4

The following sample rates are currently not working: 192, 384khz
Any attempt to use these results in a kernel hang.
Also, the attempt to use speaker-test application with 96Khz results in kernel hang.

Greetings - in attempting to build the driver on Ubuntu 23.10 I get this error:

According to the PTP_WATCHDOG_ELAPSE comment we assume to receive at least one sync each 2s its supposed to be 2s.

#define PTP_WATCHDOG_ELAPSE		20000000	// we assume to receive at least
#define NS_2_REF_UNIT 100000 // ns is the linux time unit

void get_clock_time(uint64_t* clock_time)
{
    ktime_t kt_now;
    kt_now = ktime_get();
    *clock_time = (uint64_t)ktime_to_ns(kt_now);
}

...
    uint64_t ui64CurrentRTXClockTime;
    get_clock_time(&ui64CurrentRTXClockTime);
    ui64CurrentRTXClockTime /= NS_2_REF_UNIT; // [100us]

...
        uint64_t ui64WatchDogElapse = ui64CurrentRTXClockTime - self->m_ui64LastWatchDogTime;
        if(ui64WatchDogElapse >= PTP_WATCHDOG_ELAPSE)

As I read that and have tested it for is that PTP_WATCHDOG_ELAPSE is in 100us as unit. That means that PTP_WATCHDOG_ELAPSE is 20000000 * 100us = 2000s.

I'd suggest cutting it by 1000, because then the rest of the code behaves as expected when a ptp clock is lost.

I have seen the hint with Kernel >5.2 compilation failure but what should i do if i use this kernel? Cant the __put_user_x calls just be replaced with __put_user / put_user or something like that? Is there a workaround? Even the original repository wont compile and gives me a implicit declaration of function ‘__put_user_x’; did you mean ‘put_user’? compiler error but its nothing stated that it wont work with newer Kernel versions.

Cannot compile driver on kernel 5.11:

I have compiled the Merging driver, and added it to the appropriate modules directory, but when trying to insert it, I get the following errors in dmesg.
I'm using Alpine Linux, kernel 5.10.27-lts.

It seems likely that the issue is a lack of some kind of kernel ALSA support. But I can't find any useful info towards fixing this; as far as I can tell Alpine should work just fine with sound.
