tools/power/x86/intel-speed-select: Fix file descriptor leak in isolate_cpus()2026-01-17T00:03:21ZMalaya Kumar Rout2026-01-15T10:03:33Zurn:sha1:56c17ee151c6e1a73d77e15b82a8e2130cd8dd16
The file descriptor opened in isolate_cpus() when (!level) is true was
not being closed before returning, causing a file descriptor leak in
both the error path and the success path.
When write() fails at line 950, the function returns at line 953 without
closing the file descriptor. Similarly, on success, the function returns
at line 956 without closing the file descriptor.
Add close(fd) calls before both return statements to fix the resource
leak. This follows the same pattern used elsewhere in the same function
where file descriptors are properly closed before returning (see lines
1005 and 1027).

tools/power/x86/intel-speed-select: Use pkg-config for libnl-3.0 detection2026-01-17T00:03:20ZKhem Raj2025-12-29T20:45:06Zurn:sha1:21adcd5ec99f342489a49e9d237a987b1bd9fab5
Replace hardcoded libnl3 include path with pkg-config detection to
improve portability across different distributions and build environments.
The previous implementation used a fixed path constructed from the
compiler's sysroot, which could fail on systems with non-standard
library installations. Now the build system:
- Attempts to detect libnl-3.0 include paths using pkg-config
- Falls back to /usr/include/libnl3 if pkg-config is unavailable
- Maintains backward compatibility with existing build configurations
This ensures the tool builds correctly on a wider range of systems
while preserving existing behavior when pkg-config is not present.

tools/power/x86/intel-speed-select: Allow non root users2026-01-17T00:03:20ZSrinivas Pandruvada2026-01-16T23:30:23Zurn:sha1:6588b8845e7387438d4b91ea86e7cb6d838b3108
When permitted by the file /dev/isst_interface, allow to issue commands
for non root users.
When user id is non root, check if "/dev/isst_interface" can still be
opened. If this file can be opened, allow all read only commands.

With SST-TF version 2 only 3 buckets are present. The information in
others buckets can be junk. So initialize the info structure of type
isst_turbo_freq_info, before issing ioctl to get bucket information.

After change of enable/disable status of SST-CP, SST-TF and SST-BF
check if the hardware status change was successful. If not successful
even after retries, return failure.

On SST PP level switch, skip adjusting the uncore frequency limit and
allow the hardware to handle this on newer platforms.
As newer generations of CPUs have changed the extended family identifier,
use this identifier to exclude the update.
