okay so bestie, you're reading the Kernel API Manual entry for ipa_cmd_table_init_add β yes THAT one, the table init command adder. sit down, hydrate, let's go π«Ά
β¨ NAME β¨
ipa_cmd_table_init_add β adds a table init command to a transaction, literally what it says on the tin π
πΈ SYNOPSIS πΈ
void ipa_cmd_table_init_add (struct gsi_trans *trans , enum
ipa_cmd_opcode opcode , u16 size , u32 offset , dma_addr_t addr , u16
hash_size , u32 hash_offset , dma_addr_t hash_addr );
like, that's a LOT of parameters babe, but we're gonna get through them together, one by one, no cap π₯
π ARGUMENTS π
transβ GSI transaction. the whole vibe container for the operation, iykykopcodeβ IPA immediate command opcode. tells it which command we're doing (it's anenum ipa_cmd_opcode, keep up π )sizeβ size of non-hashed routing table memoryoffsetβ offset in IPA shared memory of non-hashed routing table memoryaddrβ DMA address of non-hashed table data to writehash_sizeβ size of hashed routing table memoryhash_offsetβ offset in IPA shared memory of hashed routing table memoryhash_addrβ DMA address of hashed table data to write
see? not scary, just long. you got this π€
π¦ DESCRIPTION π¦
okay so the one actually important little detail here:
if hash_size is 0, then hash_offset and hash_addr are ignored. like, they're literally not even looked at. so don't stress about filling those in when there's no hash table in play β they're giving background extra energy, not main character energy π
π SEE ALSO π
bestie the whole friend group is in the kernel file ./drivers/net/ipa/ipa_cmd.h, please go say hi π

and that's a wrap bestie!! this page lives in ./drivers/net/ipa and it's dated October 2026 β so it's from the future?? slay, we stan a time-traveling manpage π§π mwah, go write your table init commands, you're gonna ate π
