Disable more stuff for Ubuntu/Debian Currently, the kernel emits a notice at boot, warning about the usage of trace_printk(). Disabling samples in efaa3edaaa3b ("Do not build samples for Debian/Ubuntu") apparently wasn't enough to get rid of that. So disable more sample and testing stuff that might call this function. 2021-05-31 22:29:38 +00:00			`## Do not build samples and tests`

pkg/debian: Disable CONFIG_DEBUG_MISC in kernel config This should only be used for debugging. 2021-10-09 11:15:33 +00:00			`# CONFIG_DEBUG_MISC is not set`
pkg/debian: Disable CONFIG_UBSAN in kernel config Recent Ubuntu mainline versions have enabled UBSAN. UBSAN has a runtime cost and should only be enabled for debugging and testing. Furthermore, UBSAN actively causes problems on the Surface Pro 4 and Surface Book 1, preventing them from waking from suspend in some instances. Disabling UBSAN should work around issue #585. 2021-10-09 11:16:24 +00:00			`# CONFIG_UBSAN is not set`

pkg/ubuntu: Disable atomisp While the atomisp driver might be used for Surface 3 and Surface Pro 3 cameras in the future, it currently resides in staging and doesn't seem to work (at least according to its TODO file). It furthermore causes a notice to be printed, warning about the use of trace_printk(). So disable it for now to shut up that warning. 2021-06-13 19:28:50 +00:00			`##`
