net: ipa: sort all includes

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

Establish the rule that header files are always included in sorted (POSIX local) order. Standard and private headers are separated by a blank line. Similarly, sort all forward-declarations for structures. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: pass a platform device to ipa_reg_init()

2024-03-04T11:44:40+00:00

Rather than using the platform device pointer field in the IPA pointer, pass a platform device pointer to ipa_reg_init(). Use that pointer throughout that function. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: add IPA v5.5 register definitions

2023-11-24T12:18:55+00:00

GSI register definitions for IPA v5.5 are the same as those used for IPA v5.0. Update ipa_reg_id_valid() to reflect that IPA v5.0+ supports source and destination resource groups 4 through 7. Add the definitions of IPA register offsets and fields for IPA v5.5. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

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: fix some register validity checks

2023-03-17T04:33:18+00:00

A recent commit defined HW_PARAM_4 as a GSI register ID but did not add it to gsi_reg_id_valid() to indicate it's valid (for IPA v5.0+). Add version checks for the HW_PARAM_2 and INTER_EE IRQ GSI registers there as well. IPA v5.0 supports up to 8 source and destination resource groups. Update the validity check (and the comments where the register IDs are defined) to reflect that. Similarly update comments and validity checks for the hash/cache-related registers. Note that this patch fixes an omission and constrains things further, but these don't technically represent bugs.

net: ipa: kill FILT_ROUT_CACHE_CFG IPA register

2023-03-17T04:33:18+00:00

A recent commit defined a few IPA registers used for IPA v5.0+. One of those was a mistake. Although the filter and router caches get *flushed* using a single register, they use distinct registers (ENDP_FILTER_CACHE_CFG and ENDP_ROUTER_CACHE_CFG) for configuration. And although there *exists* a FILT_ROUT_CACHE_CFG register, it is not needed in upstream code. So get rid of definitions related to FILT_ROUT_CACHE_CFG, because they are not needed.

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: tighten up IPA register validity checking

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

When checking the validity of an IPA register ID, compare it against all possible ipa_reg_id values. Rename the function ipa_reg_id_valid() to be specific about what's being checked. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: get rid of ipa->reg_addr

2023-02-10T08:06:31+00:00

The reg_addr field in the IPA structure is set but never used. Get rid of it. 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
