net: ipa: add IPA v5.0 configuration data

2023-03-23T05:44:00+00:00

Add the configuration data required for IPA v5.0, which is used in the SDX65 SoC. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: add IPA v5.0 GSI register definitions

2023-03-23T05:44:00+00:00

Add the definitions of GSI register offsets and fields for IPA v5.0. These are used for the SDX65 SoC. Increase the maximum channel and event ring counts supported by the driver, so those implemented by the SDX65 are supported. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: add IPA v5.0 register definitions

2023-03-23T05:44:00+00:00

Add the definitions of IPA register offsets and fields for IPA v5.0. These are used for the SDX65 SoC. In the Makefile, split IPA_VERSIONS to use IPA_REG_VERSIONS and IPA_DATA_VERSIONS instead, to allow IPA register definitions for a new version to be added separate from the IPA data. Rename GSI_IPA_VERSIONS to be GSI_REG_VERSIONS for consistency. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: add "gsi_v4.11.c"

2023-02-15T04:39:39+00:00

The next patch adds a GSI register field that is only valid starting at IPA v4.11. Create "gsi_v4.11.c" from "gsi_v4.9.c", changing only the name of the public regs structure it defines. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: populate more GSI register files

2023-02-15T04:39:38+00:00

Create "gsi_v4.0.c", "gsi_v4.5.c", and "gsi_v4.9.c" as essentially identical copies of "gsi_v3.5.1.c". The only difference is the name of the exported "gsi_regs_vX_Y" structure. The next patch will start differentiating them. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: add "gsi_v3.5.1.c"

2023-02-13T09:56:16+00:00

The next patch adds a GSI register field that is only valid starting at IPA v3.5.1. Create "gsi_v3.5.1.c" from "gsi_v3.1.c", changing only the name of the public regs structure it defines. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: start creating GSI register definitions

2023-02-13T09:56:16+00:00

Create a new register definition file in the "reg" subdirectory, and begin populating it with GSI register definitions based on IPA version. The GSI registers haven't changed much, so several IPA versions can share the same GSI register definitions. As with IPA registers, an array of pointers indexed by GSI register ID refers to these register definitions, and a new "regs" field in the GSI structure is initialized in gsi_reg_init() to refer to register information based on the IPA version (though for now there's only one). The new function gsi_reg() returns register information for a given GSI register, and the result can be used to look up that register's offset. This patch is meant only to put the infrastructure in place, so only eon register (CH_C_QOS) is defined for each version, and only the offset and stride are defined for that register. Use new function gsi_reg() to look up that register's information to get its offset, This makes the GSI_CH_C_QOS_OFFSET() unnecessary, so get rid of it.

net: ipa: introduce gsi_reg_init()

2023-02-13T09:56:16+00:00

Create a new source file "gsi_reg.c", and in it, introduce a new function to encapsulate initializing GSI registers, including looking up and I/O mapping their memory. Create gsi_reg_exit() as the inverse of the init function. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: add IPA v4.7 support

2022-12-12T23:55:06+00:00

Add the necessary register and data definitions needed for IPA v4.7, which is found on the SM6350 SoC. Co-developed-by: Luca Weiss Signed-off-by: Luca Weiss Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: add per-version IPA register definition files

2022-09-28T01:42:49+00:00

Create a new subdirectory "reg", which contains a register definition file for each supported version of IPA. Each register definition contains the register's offset, and for parameterized registers, the stride (distance between consecutive instances of the register). Finally, it includes an all-caps printable register name. In these files, each IPA version defines an array of IPA register definition pointers, with unsupported registers defined with a null pointer. The array is indexed by the ipa_reg_id enumerated type. At initialization time, the appropriate register definition array to use is selected based on the IPA version, and assigned to a new "regs" field in the IPA structure. Extend ipa_reg_valid() so it fails if a valid register is not defined. This patch simply puts this infrastructure in place; the next will use it.
