asd_verify_lseq(9)
β¨ asd_verify_lseq β it's giving microcode verification π
okay so real talk, bestie: this is page asd_verify_lseq(9) from the Kernel API Manual, and it's literally here to make sure a link sequencer's microcode is actually the real deal. no cap. π¦
πΈ NAME πΈ
asd_verify_lseq β verify the microcode of a link sequencer β¨
π SYNOPSIS π
int asd_verify_lseq (struct asd_ha_struct *asd_ha , const u8 *_prog ,
u32 size , int lseq );
that's the whole vibe check right there, periodt. π
π«Ά ARGUMENTS π«Ά
asd_haβ pointer to host adapter structure. the main character of this whole situation π_progβ pointer to the microcode. like, the actual bytes we're lowkey checking πsizeβ size of the microcode in bytes. gotta know how much we're working with, iykyklseqβ link sequencer of interest. yes bestie, of interest π
π₯ DESCRIPTION π₯
okay so here's the lore. the link sequencer code gets accessed in 4 KB pages, and those pages are selected by setting LmRAMPAGE (that's bits 8 and 9 of the LmBISTCTL1 register). iconic register behaviour tbh. β¨
then the 10 KB LSEQm instruction code is mapped, page at a time, at the LmSEQRAM address. one page at a time, no cutting corners, no skipping. fr fr. π§
so like, if you're wondering why 4 KB pages for 10 KB of codeβ¦ yeah, math is math and the hardware said what it said π
π SEE ALSO π
the whole friend group, honestly β no one's getting left out π«Ά

aaaand that's the page, bestie π this whole thing lives under ./drivers/scsi/aic94xx, it's dated October 2026, and the man page name is asd_verify_lseq(9) β go verify some sequencer microcode, slay, and hydrate while you're at it π β¨
