πŸ’… ipa_cmd_table_init_add(9) πŸ’…

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 🫢


✨ NAME ✨

ipa_cmd_table_init_add β€” adds a table init command to a transaction, literally what it says on the tin πŸ’–


🌸 SYNOPSIS 🌸

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 πŸ”₯


πŸŽ€ ARGUMENTS πŸŽ€

  • trans β€” GSI transaction. the whole vibe container for the operation, iykyk
  • opcode β€” IPA immediate command opcode. tells it which command we're doing (it's an enum ipa_cmd_opcode, keep up πŸ’…)
  • size β€” size of non-hashed routing table memory
  • offset β€” offset in IPA shared memory of non-hashed routing table memory
  • addr β€” DMA address of non-hashed table data to write
  • hash_size β€” size of hashed routing table memory
  • hash_offset β€” offset in IPA shared memory of hashed routing table memory
  • hash_addr β€” DMA address of hashed table data to write

see? not scary, just long. you got this 😀


πŸ¦‹ DESCRIPTION πŸ¦‹

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 πŸ’€

bestie the whole friend group is in the kernel file ./drivers/net/ipa/ipa_cmd.h, please go say hi πŸ‘‘

like literally the entire crew, go read them all, i'll wait πŸ“
