Hello everybody,
since Kernel 5.6.5 I encounter many syslog lines like
[kernel] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS. - Last output repeated 4 times -
I found some explanation at: https://wiki.archlinux.org/index.php/intel_graphics#Framebuffer_compression_...) But why do I get this with a i7-4790 Haswell, which is not pre-Sandy?
Anyway I followed the hint and set
# cat /etc/modprobe.d/i915.conf options i915 enable_fbc=0
After reboot the setting seems active:
# cat /sys/module/i915/parameters/enable_fbc 0
But I still get the same logs. Which BIOS setting is responsible, how can I fix that? Is there a better place to ask?
# lspci |grep VGA 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
