+ * This means we don't know if the SRM is good until the last call. And because of this limitation we
+ * cannot throw errors early as it will stop the kernel from writing to sysfs
+ *
+ * Example 1:

+ * 	Second call to write 1000 -> PSP Pass -> SRM is set

+ * Solution?:

+ *
+ * For example,

+ * 	needs to use HDCP, the version in PSP should be SRM(ver 2). So SRM should be persistent
+ * 	across boot/reboots/suspend/resume/shutdown
+ *
+ * Currently when the system goes down (suspend/shutdown) the SRM is cleared from PSP. For HDCP we need
+ * to make the SRM persistent.
+ *
+ * -PSP owns the checking of SRM but doesn't have the ability to store it in a non-volatile memory.
+ * -The kernel cannot write to the file systems.
+ * -So we need usermode to do this for us, which is why an interface for usermode is needed
+ *
+ *
+ *
+ * Usermode can read/write to/from PSP using the sysfs interface
+ * For example:
+ * 	to save SRM from PSP to storage : cat /sys/class/drm/card0/device/hdcp_srm > srmfile
+ * 	to load from storage to PSP: cat srmfile > /sys/class/drm/card0/device/hdcp_srm

+ * We need to know as early as possible if we're going to use GuC or not to
+ * take the correct setup paths. Additionally, once we've started loading the
+ * GuC, it is unsafe to keep executing without it because some parts of the HW,
+ * a subset of which is not cleaned on GT reset, will start expecting the GuC FW
+ * to be running.
+ * To solve both these requirements, we commit to using the microcontrollers if
+ * the relevant modparam is set and the blobs are found on the system. At this
+ * stage, the only thing that can stop us from attempting to load the blobs on
+ * the HW and use them is a fundamental issue (e.g. no memory for our
+ * structures); if we hit such a problem during driver load we're broken even
+ * without GuC, so there is no point in trying to fall back.
+ *
+ * Given the above, we can be in one of 4 states, with the last one implying
+ * we're committed to using the microcontroller:
+ * - Not supported: not available in HW and/or firmware not defined.
+ * - Supported: available in HW and firmware defined.
+ * - Wanted: supported + enabled in modparam.
+ * - In use: wanted + firmware found on the system and successfully fetched.

- * - Driver: saved/restored by the driver
- * - Punit : saved/restored by the Punit firmware
- * - No, w/o marking: no need to save/restore, since the register is R/O or
- *                    used internally by the HW in a way that doesn't depend
- *                    keeping the content across a suspend/resume.
- * - Debug : used for debugging
- *
- * We save/restore all registers marked with 'Driver', with the following
- * exceptions:
- * - Registers out of use, including also registers marked with 'Debug'.
- *   These have no effect on the driver's operation, so we don't save/restore
- *   them to reduce the overhead.
- * - Registers that are fully setup by an initialization function called from
- *   the resume path. For example many clock gating and RPS/RC6 registers.
- * - Registers that provide the right functionality with their reset defaults.
- *
- * TODO: Except for registers that based on the above 3 criteria can be safely
- * ignored, we save/restore all others, practically treating the HW context as
- * a black-box for the driver. Further investigation is needed to reduce the
- * saved/restored registers even further, by following the same 3 criteria.

+ * registers in the following way:
+ * - Driver: saved/restored by the driver
+ * - Punit : saved/restored by the Punit firmware
+ * - No, w/o marking: no need to save/restore, since the register is R/O or
+ *                    used internally by the HW in a way that doesn't depend
+ *                    keeping the content across a suspend/resume.
+ * - Debug : used for debugging
+ *
+ * We save/restore all registers marked with 'Driver', with the following
+ * exceptions:
+ * - Registers out of use, including also registers marked with 'Debug'.
+ *   These have no effect on the driver's operation, so we don't save/restore
+ *   them to reduce the overhead.
+ * - Registers that are fully setup by an initialization function called from
+ *   the resume path. For example many clock gating and RPS/RC6 registers.
+ * - Registers that provide the right functionality with their reset defaults.
+ *
+ * TODO: Except for registers that based on the above 3 criteria can be safely
+ * ignored, we save/restore all others, practically treating the HW context as
+ * a black-box for the driver. Further investigation is needed to reduce the
+ * saved/restored registers even further, by following the same 3 criteria.
