* HGSL
|
||
|
|
|
||
|
|
HGSL(Hypervisor Graphics system layer) is graphics driver under the hypervisor system.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : Must be "qcom,hgsl"
|
||
|
|
|
||
|
|
- reg : physical base address and length of the register set(s).
|
||
|
|
|
||
|
|
- reg-names : names corresponding to each reg property value.
|
||
|
|
reg_hwver: HW version registers
|
||
|
|
reg_doorbell_idx: address of GMUAO_DOORBELL_IDX
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- db-off: Disable Doorbell feature but keep hgsl for ifence service
|
||
|
|
- qcom,glb-db-senders : Point to possible nodes of HGSL TCSR sender. The user will select
|
||
|
|
which sender to use. The driver will use TCSR compute signal to
|
||
|
|
send signal to GPU.
|
||
|
|
- qcom,glb-db-receivers : Point to possible nodes of HGSL TCSR receiver. The user will
|
||
|
|
select which receiver to use. The driver will use TCSR compute
|
||
|
|
signal to receive signal from GPU.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
msm_gpu_hyp {
|
||
|
|
compatible = "qcom,hgsl";
|
||
|
|
reg = <0x2c00000 0x8>, <0x2c8f000 0x4>;
|
||
|
|
reg-names = "hgsl_reg_hwinf", "hgsl_reg_gmucx";
|
||
|
|
|
||
|
|
db-off = <0>;
|
||
|
|
qcom,glb-db-senders = <&hgsl_tcsr_sender0 &hgsl_tcsr_sender1>;
|
||
|
|
qcom,glb-db-receivers = <&hgsl_tcsr_receiver0 &hgsl_tcsr_receiver1>;
|
||
|
|
};
