Case 1:
file 10-opcache.ini has additional lines:
opcache.jit_buffer_size=256M
opcache.jit=1255
PHP-FPM has additional lines:
php_value[opcache.jit] = 1255
php_value[opcache.jit_buffer_size] = 105M
phpinfo() output:

Looks like opcache.jit_buffer_size is different.
Case 2:
Case 1:
file 10-opcache.ini has no any additional variables.
PHP-FPM has additional lines:
php_value[opcache.jit] = 1255
php_value[opcache.jit_buffer_size] = 105M
var_dump(opcache_get_status()['jit']) output:
array(7) {
["enabled"]=>
bool(false)
["on"]=>
bool(false)
["kind"]=>
int(5)
["opt_level"]=>
int(4)
["opt_flags"]=>
int(6)
["buffer_size"]=>
int(0)
["buffer_free"]=>
int(0)
}
phpinfo() output:

It leads me to confusion.
I've been following https://stitcher.io/blog/php-8-jit-setup guide.
I'm using https://rpms.remirepo.net/ , the latest version:
PHP -v:
PHP 8.0.0 (cli) (built: Nov 24 2020 17:04:03) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies
with Zend OPcache v8.0.0, Copyright (c), by Zend Technologies
Is it possible to enable jit via FPM?
p.s. I'm happy to provide full details/files on this case.

multi-master-multi-version setup. Or in other words, every user can have multi-version php-fpm and own opcache at the same time. However, I'm not able to enable/disable JIT via php-fpm config (only via opcache.ini, globally). question: is there a way to do that via fpm config? CONFIGURATION #1: "opcache.jit_buffer_size=256M" is set in opcache.ini file, "php_value[opcache.jit_buffer_size] = 240M" is set in FPM config. Function call to opcache_get_status() ['jit'] returns 268435440 as "buffer_size". phpinfo() returns "opcache.jit_buffer_size 240M 240M" CONFIGURATION #2: "php_value[opcache.jit_buffer_size] = 240M" is set in FPM config. Function call to opcache_get_status(), ['jit'] returns 0 as "buffer_size", however the opcache part from phpinfo() displays "opcache.jit_buffer_size 240M 240M"
