[igt-dev] [PATCH i-g-t 1/3] i915/gem_ctx_persistence: Use "%u" for -1u conversion

[igt-dev] [PATCH i-g-t 1/3] i915/gem_ctx_persistence: Use "%u" for -1u conversion

[Chris Wilson]

The debugfs modparams are more picky and refuse to do the implicit
unsigned conversion.

[igt-dev] [PATCH i-g-t 2/3] Always pass device to igt_params_set

[Chris Wilson]

Don't second guess, require the user to provide the device that wish to
set the module parameter for.

[igt-dev] [PATCH i-g-t 3/3] lib: Cleanup __igt_params_open()

[Chris Wilson]

The device always exist, so use it to derive the module name required to
lookup either the debugfs params directory or the sysfs module parameters.

Fixes: 2f5cee33ce55 ("igt/params: use igt_params_set_save for igt_set_module_param*")

I was wondering about this until I realized "reset" in i915_params.h has
type unsigned int, while the module param in i915_params.c has type
int. It's not that the debugfs is more picky, it's just that they have
different types!

BR,
Jani.
