2023-02-14cxl/pci: Break out range register decoding from cxl_hdm_decode_init()Dave Jiang
There are 2 scenarios that requires additional handling. 1. A device that has active ranges in DVSEC range registers (RR) but no HDM decoder register block. 2. A device that has both RR active and HDM, but the HDM decoders are not programmed. The goal is to create emulated decoder software structs based on the RR. Move the CXL DVSEC range register decoding code block from cxl_hdm_decode_init() to its own function. Refactor code in preparation for the HDM decoder emulation. There is no functionality change to the code. Name the new function to cxl_dvsec_rr_decode(). The only change is to set range->start and range->end to CXL_RESOURCE_NONE and skipping the reading of base registers if the range size is 0, which equates to range not active.

2023-02-14net/mlx5: Lag, Control MultiPort E-Switch single FDB modeRoi Dayan
MultiPort E-Switch builds on newer hardware's capabilities and introduces a mode where a single E-Switch is used and all the vports and physical ports on the NIC are connected to it. The new mode will allow in the future a decrease in the memory used by the driver and advanced features that aren't possible today. This represents a big change in the current E-Switch implantation in mlx5. Currently, by default, each E-Switch manager manages its E-Switch. Steering rules in each E-Switch can only forward traffic to the native physical port associated with that E-Switch. While there are ways to target non-native physical ports, for example using a bond or via special TC rules. None of the ways allows a user to configure the driver to operate by default in such a mode nor can the driver decide to move to this mode by default as it's user configuration-driven right now. While MultiPort E-Switch single FDB mode is the preferred mode, older generations of ConnectX hardware couldn't support this mode so it was never implemented. Now that there is capable hardware present, start the transition to having this mode by default. Introduce a devlink parameter to control MultiPort E-Switch single FDB mode. This will allow users to select this mode on their system right now and in the future will allow the driver to move to this mode by default.

[Why] We only allowed 1 overlay plane. But now some ASICS can support multiple overlay planes. [How] Use max_slave_planes as the number of overlays we can support. Also since we cannot draw cursor over a video plane, we need to make sure that we reject commits where the topmost plane is a video plane (overlay only).

2023-02-14drm/amd/display: move public dc link function implementation to dc_link_exportsWenjing Liu
[why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

2023-02-14drm/amd/display: Disable unbounded request mode during rotationNasir Osman
[why] HUBP_UNBOUNDED_REQ_MODE being enabled while the display is rotated (eg. going from Portrait mode to Landscape mode) appears to be causing a p-state hang, specifically during full screen mode on the Tiktok PC app. Unbounded request mode doesn't appear to be supported with rotation configs, hence disabling it. [how] Within DML, modified unbounded request mode to be configured only when the rotation angle of the plane is 0.

2023-02-14drm/amdgpu: Revert programming GRBM_GFX_* in RLCG interface to support GFX9Yifan Zha
[Why] Regression of commit 72fef4980ddf ("drm/amdgpu: Remove writing GRBM_GFX_CNTL in RLCG interface under SRIOV") on GFX9. According to GFX9 VF using different method to access GC registers including MMIO(direct) and RLCG(indirect), removing GRBM_GFX_* writing would make PIPE/ME/VM/QUEUE selection chaos leading to some OCL benchmark failure. For example, using RLCG interface to program GRBM_GFX_CNTL/INDEX for selecting MEC(actually the value is only in scratch2/3), then using MMIO directly program a MEC register in VF driver. The register programming are invalid due to GC switched to incorrect ME. [How] With checking RLCG accessing flag, keep writing GRBM_GFX_* as a legacy way. But it is still skipped on GFX10+ to avoid violation occurrence.
