# WARNING/NOTE: whenever you want to add an option here you need to either
|
|
|
|
|
# * mark it as an optional one with `option`,
|
|
|
|
|
# * or make sure it works for all the versions in nixpkgs,
|
|
|
|
|
# * or check for which kernel versions it will work (using kernel
|
|
|
|
|
# changelog, google or whatever) and mark it with `whenOlder` or
|
|
|
|
|
# `whenAtLeast`.
|
|
|
|
|
# Then do test your change by building all the kernels (or at least
|
|
|
|
|
# their configs) in Nixpkgs or else you will guarantee lots and lots
|
|
|
|
|
# of pain to users trying to switch to an older kernel because of some
|
|
|
|
|
# hardware problems with a new one.

linux: Disable DRM_LEGACY, NOUVEAU_LEGACY_CTX_SUPPORT
This currently gets enabled as generate-config.pl will enable all the
drivers below it as modules.
Is “not set” in [Arch][1], [Debian][2], [Fedora][3]. See also [summary
of setting from various distros in April 2020][4].
Recommended disabled by [CLIP OS][5] and per current [Kernel config
description][6]:
> bool "Enable legacy drivers (DANGEROUS)"
> Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
> APIs to user-space, which can be used to circumvent access
> restrictions and other security measures. For backwards compatibility
> those drivers are still available, but their use is highly
> inadvisable and might harm your system.
>
> You are recommended to use the safe modeset-only drivers instead, and
> perform 3D emulation in user-space.
>
> Unless you have strong reasons to go rogue, say "N".
Also disable NOUVEAU_LEGACY_CTX_SUPPORT, as this does `select
DRM_LEGACY`. Per Kernel config docs:
>There was a version of the nouveau DDX that relied on legacy
> ctx ioctls not erroring out. But that was back in time a long
> ways, so offer a way to disable it now. For uapi compat with
> old nouveau ddx this should be on by default, but modern distros
> should consider turning it off.
and the [commit][7]:
> These driver functions contain several bugs and security holes. This
> change makes these functions optional can be turned on by a setting,
> they are turned off by default for modeset driver with the exception of
> the nouvea driver that may require them with an old version of libdrm.
Referenced earlier commit elaborates that
> libdrm_nouveau before 2.4.33 used contexts
Since nixpkgs here has a much newer version (2.4.33 is from March 2012),
should not be a concern.
NOUVEAU_LEGACY_CTX_SUPPORT is also “not set” in the linked Arch, Debian,
& Fedora configs.

linux: enable TASKSTATS, TASK_XACCT, TASK_DELAY_ACCT and TASK_IO_ACCOUNTING
iotop needs TASKSTATS, TASK_DELAY_ACCT, TASK_XACCT and
TASK_IO_ACCOUNTING to work. For x86_64, all these options are enabled
by upstream[1]. For aarch64, however, only TASK_XACCT and
TASK_IO_ACCOUNTING are enabled by upstream[2].
This patch enables all these four options for aarch64, which have been
enabled by many other distributions, e.g. debian[3], fedora[4],
rhel[5] and gentoo[6].
I tried to only enable TASKSTATS and TASK_DELAY_ACCT since the other
two options are enabled by upstream, but it turns out that it's
necessary to explicitly enable all four options. I do not figure out
the reason though.
Additionally, given that debian enables these four options for all
arch[3], I think it's safe for us to do the same thing.
