[This seems likely to not be limited to main [so: 15 as stands].
But I'm using main as the example for the issue.]
In:
# man 5 device.hints
DEVICE.HINTS(5) FreeBSD File Formats Manual =
DEVICE.HINTS(5)
NAME
device.hints =E2=80=93 device resource hints
. . .
FILES
/boot/device.hints Device resource hints =
file.
/sys/ARCH/conf/GENERIC.hints Sample resource hints =
for the
GENERIC kernel.
/sys/ARCH/conf/NOTES Notes on the kernel
configuration file and =
device
resource hints.
. . .
For reference:
# find -s / -name GENERIC.hints -print
/usr/src/sys/amd64/conf/GENERIC.hints
/usr/src/sys/i386/conf/GENERIC.hints
/usr/src/sys/powerpc/conf/GENERIC.hints
Multiple points:
) It seems that aarch64 (arm64?) and armv7 (arm?) have no
such GENERIC.hints file. The same goes for riscv64
(riscv?).
The intent for powerpc64 , powerpc64le , and powerpcspe
may have the same issue.
) At least for how the local systems were installed, there
is no such place predefined as /sys/ , not even as a
symbolic link. "man 7 hier" does not list such.
So it seems /sys -> /usr/src/sys is intended. (But
/usr/src/ need not have been populated, leaving a
lack of any GENERIC.hints in such a case.)
Best to not to depend on /sys in the notation shown?
) The /ARCH/ reference is unclear vs. MACHINE,
MACHINE_CPUARCH, and MACHINE_ARCH. The example paths
existing for GENERIC.hints do not help because they
all allow MACHINE =3D=3D MACHINE_CPUARCH ,
MACHINE =3D=3D MACHINE_ARCH , and
MACHINE_CPUARCH =3D=3D MACHINE_ARCH. However, based on the
NOTE paths:
# find -s /usr/src/ -name NOTES -print | grep /conf/NOTES | more
/usr/src/sys/amd64/conf/NOTES
/usr/src/sys/arm/conf/NOTES
/usr/src/sys/arm64/conf/NOTES
/usr/src/sys/conf/NOTES
/usr/src/sys/i386/conf/NOTES
/usr/src/sys/powerpc/conf/NOTES
/usr/src/sys/riscv/conf/NOTES
/usr/src/sys/x86/conf/NOTES
None of of the MACHINE* are right: x86 is not one of
any of the 3. Otherwise /arm64/conf/NOTES would suggest
MACHINE as the only possibility if /ARCH/ was uniform
for relative to the 3 MACHINE* possibilities. So?:
/usr/src/sys/arm64/conf/GENERIC.hints
/usr/src/sys/arm/conf/GENERIC.hints
/usr/src/sys/riscv/conf/GENERIC.hints
with no aarch64 , armv7 , powerpc64* , powerpcspe , or
riscv64 examples?
=3D=3D=3D
