Failures

Contains the list of all possible failures for functions present on the system.

These are the anticipated possible failures a function can experience in our codebase.

Global device_exists (const char *device_name)

Invalid File - The only way this function can fail is by not having the file in question exist.

Global get_major (const char *device)

Invalid Device - In the case of an invalid device being passed it will return -1.

Device List Not Found - Device list is not found, this can occur on unsupported operating systems.

Global get_param (const char *filename, const char *parameter)

Param File Not Found - Check if the device driver is loaded correctly.

Global nv_open (int32_t major, uint16_t minor, const char *path, const char *proc_path)

Not Created - Normally this is the case if the NVIDIA driver is not loaded.

Global nv_open_dev (uint16_t minor)

Not Created - Normally this is the case if the NVIDIA driver is not loaded.

Global nv_open_mdev (uint16_t minor)

Not Created - Normally this is the case if the NVIDIA driver is not loaded.

Global rm_alloc_res (int fd, struct NvResource *parent, uint32_t object, uint32_t rm_class, void *data)

Invalid File Descriptor - Occurs when fd is -1.

Incorrect File Descriptor - Occurs when fd is an incorrect descriptor.

Global rm_ctrl_res (int fd, uint32_t client, uint32_t device, uint32_t command, void *data, uint32_t size)

Invalid File Descriptor - Occurs when fd is -1.

Incorrect File Descriptor - Occurs when the fd is an incorrect file descriptor.

RM Failure - Occurs when incorrect information is placed.

Global rm_free_res (int fd, struct NvResource *object)

Invalid File Descriptor - Occurs when fd is -1.

Incorrect File Descriptor - Occurs when the fd is an incorrect file descriptor.

Global rm_version_check (int ctl_fd, uint8_t ignore_version, const char *version)

Invalid File Descriptor - This occurs when ctl_fd is -1.

Invalid RM Version - This will occur when there is a mismatch on the driver and the user suite.

Seg Fault - This occurs if version is not pointing to NULL but is pointing to a previously allocated memory address.
