As part of enabling GuC submission [1] we need to update to the latest
and greatest firmware. This series does that. All backwards
compatibility breaking changes squashed into a single patch #2. Same
series sent to trybot [2] forcing GuC to be enabled to ensure we haven't
broke something.
v2: Address comments, looking for remaning RBs so patches can be
squashed and sent for CI
v3: Delete a few unused defines, squash patches
v4: Add values back into kernel doc, fix docs warning

New GuC firmware will unify format of MMIO and CTB H2G messages.
Introduce their definitions now to allow gradual transition of
our code to match new changes.

To: intel-gfx, dri-devel
Cc: daniele.ceraolospurio, john.c.harrison, Michal.Wajdeczko
From: Michal Wajdeczko <michal.wajdeczko@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.

*
- * The message header consists of:

+ * are, regardless on lower count, preferred over legacy ones.

- * - **REQUEST**, indicates Host-to-GuC request, requested GuC action code
- * must be priovided in **code** field. Optional action specific parameters

- *
- * - **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**

* [Intel-gfx] [PATCH 2/3] drm/i915/guc: Update firmware to v62.0.0
@ 2021-06-16 0:13 ` Matthew Brost
0 siblings, 0 replies; 20+ messages in thread
From: Matthew Brost @ 2021-06-16 0:13 UTC (permalink / raw)
To: intel-gfx, dri-devel
From: Michal Wajdeczko <michal.wajdeczko@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.

*
- * The message header consists of:

+ * are, regardless on lower count, preferred over legacy ones.

- * - **RESPONSE**, indicates GuC-to-Host response from earlier GuC request,
- * action response status will be provided in **code** field. Optional

KMS pipe state mismatch wouldn't be related to the GuC changes here.

* [PATCH 0/3] Update firmware to v62.0.0

As part of enabling GuC submission [1] we need to update to the latest
and greatest firmware. This series does that. All backwards
compatibility breaking changes squashed into a single patch #2. Same
series sent to trybot [2] forcing GuC to be enabled to ensure we haven't
broke something.
v2: Address comments, looking for remaning RBs so patches can be
squashed and sent for CI
v3: Delete a few unused defines, squash patches
