net: ipa: remove unneeded standard includes

2024-04-18T11:01:05+00:00

Some IPA header files include one or more other standard header files despite not directly needing anything defined in the included files. Remove these unnecessary includes. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: generalize register field functions

2023-02-10T08:06:32+00:00

Rename functions related to register fields so they don't appear to be IPA-specific, and move their definitions into "reg.h": ipa_reg_fmask() -> reg_fmask() ipa_reg_bit() -> reg_bit() ipa_reg_field_max() -> reg_field_max() ipa_reg_encode() -> reg_encode() ipa_reg_decode() -> reg_decode() Signed-off-by: Alex Elder Signed-off-by: David S.

net: ipa: generalize register offset functions

2023-02-10T08:06:32+00:00

Rename ipa_reg_offset() to be reg_offset() and move its definition to "reg.h". Rename ipa_reg_n_offset() to be reg_n_offset() also. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: start generalizing "ipa_reg"

2023-02-10T08:06:32+00:00

IPA register definitions have evolved with each new version. The changes required to support more than 32 endpoints in IPA v5.0 made it best to define a unified mechanism for defining registers and their fields. GSI register definitions, meanwhile, have remained fairly stable. And even as the total number of IPA endpoints goes beyond 32, the number of GSI channels on a given EE that underly endpoints still remains 32 or less. Despite that, GSI v3.0 (which is used with IPA v5.0) extends the number of channels (and events) it supports to be about 256, and as a result, many GSI register definitions must change significantly. To address this, we'll use the same "ipa_reg" mechanism to define the GSI registers. As a first step in generalizing the "ipa_reg" to also support GSI registers, isolate the definitions of the "ipa_reg" and "ipa_regs" structure types (and some supporting macros) into a new header file, and remove the "ipa_" and "IPA_" from symbol names. Separate the IPA register ID validity checking from the generic check that a register ID is in range. Aside from that, this is intended to have no functional effect on the code.

net: ipa: update copyrights

net: ipa: define resource group/type IPA register fields

2022-09-28T01:42:51+00:00

Define the fields for the {SRC,DST}_RSRC_GRP_{01,23,45,67}_RSRC_TYPE IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_STRIDE_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_encode() to build up the values to be written to these registers. Remove the definition of the no-longer-used *_FMASK symbols. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: introduce ipa_reg()

2022-09-28T01:42:50+00:00

Create a new function that returns a register descriptor given its ID. Change ipa_reg_offset() and ipa_reg_n_offset() so they take a register descriptor argument rather than an IPA pointer and register ID. Have them accept null pointers (and return an invalid 0 offset), to avoid the need for excessive error checking. (A warning is issued whenever ipa_reg() returns 0). Call ipa_reg() or ipa_reg_n() to look up information about the register before calls to ipa_reg_offset() and ipa_reg_n_offset(). Delay looking up offsets until they're needed to read or write registers. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: use IPA register IDs to determine offsets

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

Expose two inline functions that return the offset for a register whose ID is provided; one of them takes an additional argument that's used for registers that are parameterized. These both use a common helper function __ipa_reg_offset(), which just uses the offset symbols already defined. Replace all references to the offset macros defined for IPA registers with calls to ipa_reg_offset() or ipa_reg_n_offset(). Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net/ipa: ipa_resource: Fix wrong for loop range

net: ipa: kill the remaining conditional validation code

2021-07-26T21:38:11+00:00

There are only a few remaining spots that validate IPA code conditional on whether a symbol is defined at compile time. The checks are not expensive, so just build them always. This completes the removal of all CONFIG_VALIDATE/CONFIG_VALIDATION IPA code. Signed-off-by: Alex Elder Signed-off-by: David S. Miller
