Google Coral M.2 and Rocky Linux 9

To use Google Coral AI accelerator chip with Rocky Linux 9 you need a tweak or two. Here is how to do it.

dnf copr enable kylegospo/google-coral-dkms
dnf in gasket-dkms

Change directory according to the version.

vim /usr/src/gasket-0.0.git.256.b6a7c6d8/gasket_core.c

• look at line 1846 where kernel higher than 6.4.0 gets class create with 2 parameters and
• update it similar to one parameter else version: internal→class = classcreate(driverdesc→name);

Example snipplet

#if LINUX_VERSION_CODE < KERNEL_VERSION(6, 4, 0)
    //internal->class = class_create(driver_desc->module, driver_desc->name);
    internal->class = class_create(driver_desc->name);
#else
    internal->class = class_create(driver_desc->name);
#endif  

/usr/src/gasket-0.0.git.256.b6a7c6d8/gasket_interrupt.c

• look at line 161 with kernel version check (other way) and update if part similar to else
• part: eventfd_signal(ctx);

if (ctx)
       #if LINUX_VERSION_CODE >= KERNEL_VERSION(6,8,0)
                eventfd_signal(ctx);
       #else   
                //eventfd_signal(ctx, 1);
                eventfd_signal(ctx);
       #endif

dkms autoinstall

Reboot and check if /dev/apex_0 is visible. That should be it.
