Tue Nov 9 22:59:24 UTC 2021
From: Michal Wajdeczko <michal.wajdeczko at intel.com>
Most of the changes to the 62.0.0 firmware revolved around CTB
communication channel. Conform to the new (stable) CTB protocol.
v2:
(Michal)
Add values back to kernel DOC for actions
(Docs)
Add 'CT buffer' back in to fix warning

*
- * The MMIO based communication between Host and GuC uses software scratch
- * registers, where first register holds data treated as message header,
- * and other registers are used to hold message payload.
+ * The MMIO based communication between Host and GuC relies on special
+ * hardware registers which format could be defined by the software
+ * (so called scratch registers).
*
- * For Gen9+, GuC uses software scratch registers 0xC180-0xC1B8,
- * but no H2G command takes more than 8 parameters and the GuC FW
- * itself uses an 8-element array to store the H2G message.
+ * Each MMIO based message, both Host to GuC (H2G) and GuC to Host (G2H)
+ * messages, which maximum length depends on number of available scratch
+ * registers, is directly written into those scratch registers.

+ * For Gen9+, there are 16 software scratch registers 0xC180-0xC1B8,
+ * but no H2G command takes more than 4 parameters and the GuC firmware
+ * itself uses an 4-element array to store the H2G message.
*
- * The message header consists of:
+ * For Gen11+, there are additional 4 registers 0x190240-0x19024C, which
+ * are, regardless on lower count, preferred over legacy ones.
*
- * - **type**, indicates message type
- * - **code**, indicates message code, is specific for **type**
- * - **data**, indicates message data, optional, depends on **code**
- *
- * The following message **types** are supported:
- *
- * - **REQUEST**, indicates Host-to-GuC request, requested GuC action code
- * must be priovided in **code** field. Optional action specific parameters
- * can be provided in remaining payload registers or **data** field.
- *
- * - **RESPONSE**, indicates GuC-to-Host response from earlier GuC request,
- * action response status will be provided in **code** field. Optional
- * response data can be returned in remaining payload registers or **data**
- * field.
+ * The MMIO based communication is mainly used during driver initialization
+ * phase to setup the `CTB based communication`_ that will be used afterwards.
