net: ipa: update comments

2022-10-03T23:49:05+00:00

This patch just updates comments throughout the IPA code. Transaction state is now tracked using indexes into an array rather than linked lists, and a few comments refer to the "old way" of doing things. The description of how transactions are used was changed to refer to "operations" rather than "commands", to (hopefully) remove a possible ambiguity. IPA register offsets and fields are now handled differently as well, and the register documentation is updated to better describe the code. A few minor updates to comments were made (e.g., adding a missing word, fixing a typo or punctuation, etc.). Finally, the local macro atomic_dec_not_zero() is no longer used, so it is deleted.

net: ipa: define remaining IPA register fields

2022-09-28T01:42:52+00:00

Define the fields for the ENDP_INIT_DEAGGR, ENDP_INIT_RSRC_GRP, ENDP_INIT_SEQ, ENDP_STATUS, and ENDP_FILTER_ROUTER_HSH_CFG, and IPA_IRQ_UC IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_FIELDS() and IPA_REG_STRIDE_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_encode() and ipa_reg_bit() to build up the values to be written to these registers, remove an inline function and all the *_FMASK symbols that are now no longer used.

net: ipa: define more IPA endpoint register fields

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

Define the fields for the ENDP_INIT_MODE, ENDP_INIT_AGGR, ENDP_INIT_HOL_BLOCK_EN, and ENDP_INIT_HOL_BLOCK_TIMER 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. Change aggr_time_limit_encode() and hol_block_timer_encode() so they take an ipa_reg pointer, and use those register's fields to compute their encoded results. Have aggr_time_limit_encode() take an IPA pointer rather than version, to match hol_block_timer_encode(). Use ipa_reg_encode(), ipa_reg_bit(), and ipa_reg_field_max() to manipulate values to be written to these registers, remove the definitions of the various inline functions and *_FMASK symbols that are now no longer used.

net: ipa: define some IPA endpoint register fields

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

Define the fields for the ENDP_INIT_CTRL, ENDP_INIT_CFG, ENDP_INIT_NAT, ENDP_INIT_HDR, and ENDP_INIT_HDR_EXT 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. Move ipa_header_size_encoded() and ipa_metadata_offset_encoded() out of "ipa_reg.h" and into "ipa_endpoint.c". Change them so they take an additional ipa_reg structure argument, and use ipa_reg_encode() to encode the parts of the header size and offset prior to writing to the register. Change their names to be verbs rather than nouns. Use ipa_reg_encode(), ipa_reg_bit, and ipa_reg_field_max() to manipulate values to be written to these registers, remove the definition of the no-longer-used *_FMASK symbols.

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: define even more IPA register fields

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

Define the fields for the FLAVOR_0, IDLE_INDICATION_CFG, QTIME_TIMESTAMP_CFG, TIMERS_XO_CLK_DIV_CFG and TIMERS_PULSE_GRAN_CFG IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers. Use ipa_reg_decode() to extract field values from the FLAVOR_0 register.

net: ipa: define more IPA register fields

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

Define the fields for the LOCAL_PKT_PROC_CNTXT, COUNTER_CFG, and IPA_TX_CFG IPA registers for all supported IPA versions. Create enumerated types to identify fields for these IPA registers. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers. Remove the definition of the *_FMASK symbols as well as proc_cntxt_base_addr_encoded(), because they are no longer needed. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

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

Define the fields for the SHARED_MEM_SIZE, QSB_MAX_WRITES, QSB_MAX_READS, FILT_ROUT_HASH_EN, and FILT_ROUT_HASH_FLUSH IPA registers for all supported IPA versions. Create enumerated types to identify fields for these registers. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers rather than using the *_FMASK preprocessor symbols. Remove the definition of the now unused *_FMASK symbols. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: define CLKON_CFG and ROUTE IPA register fields

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

Create the ipa_reg_clkon_cfg_field_id enumerated type, which identifies the fields for the CLKON_CFG IPA register. Add "CLKON_" to a few short names to try to avoid name conflicts. Create the ipa_reg_route_field_id enumerated type, which identifies the fields for the ROUTE IPA register. Use IPA_REG_FIELDS() to specify the field mask values defined for these registers, for each supported version of IPA. Use ipa_reg_bit() and ipa_reg_encode() to build up the values to be written to these registers rather than using the *_FMASK preprocessor symbols.
