Rather than searching for drivers under a single
hardcoded directory, this change modifies
init_drivers() such that it searches under the
following ones:
System:
- /usr/share/liballocator
- /usr/local/share/liballocator
User:
- $HOME/.liballocator
And also allows users to set extra directories by
setting the following environment variable with a
colon-delimited list of paths:
__LIBALLOCATOR_EXTRA_CONF_DIRS

This changes moves the following functions to a new helpers.h header file and makes them static inline functions so they can be used by others (i.e. drivers and tests) without having to link against the allocator library: * free_capability_sets() * serialize_capability_set() * deserialize_capability_set() Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Drivers will want to stick a copy of the given capability set when creating an allocation. This change adds a dup_capability_set() static inline helper. Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Add a new utils.h header file with miscellaneous macros and static inline utility functions to be used by tests and drivers. Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Adds the infrastructure to build an allocator driver based off nouveau. Current driver implementation is just a bunch of placeholders. The actual logic will be added incrementally with follow-on changes. Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Add nouveau_driver_t and nouveau_device_t structures and the required logic to allocate a nouveau allocator device. Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Add the code to nouveau_device_get_capabilities() to return a capability set to support a pitch linear memory layout. Note this change also implements nouveau_device_get_assertion_hints() so that we can also expose the allocation maximum size supported. ./capability_set_ops test now runs and succeeds when using the nouveau driver.

Add the necessary logic to create an allocator allocation backed by a nouveau buffer object. Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Make the -f|--file option an optional one. If only -d|--drm-file is specified, assume both the drm and the allocator devices are the same (also if both options are specified but both point to the same device node). Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
Add USAGE_BASE_DISPLAY to the list of usages to test in capability_set_ops. Signed-off-by: Miguel A Vico Moya <mvicomoya@nvidia.com>
