jpeg_v4_0_5_sw_fini(9)
π jpeg_v4_0_5_sw_fini(9) β a Kernel API Manual moment
okay bestie, welcome to the Kernel API Manual, specifically the lil page for jpeg_v4_0_5_sw_fini. yes the name is a mouthful, no we're not changing it, it's iconic in a cursed way π
β¨ NAME β¨
jpeg_v4_0_5_sw_fini β literally the sw fini for the JPEG block. that's the whole vibe. software teardown, JPEG edition, slay π
β¨ SYNOPSIS β¨
int jpeg_v4_0_5_sw_fini (struct amdgpu_ip_block *ip_block );
it returns an int, it takes one arg, that's it, that's the whole signature, no cap π«Ά
β¨ ARGUMENTS β¨
ip_blockβ a pointer to theamdgpu_ip_blockfor this hw instance. like, this specific hardware instance's ip block, not some other one. pointer to the actual struct. yes the asterisk matters, bestie π¦
β¨ DESCRIPTION β¨
so what does it actually DO? two things, and honestly they're giving "closing shift at the group chat" energy:
- JPEG suspend
- free up the sw allocation
that's it. that's the function. it suspends JPEG and releases the software allocation. short, sweet, ate and left no crumbs π₯
ngl the description is only one line in the og, so there's nothing more to spill β don't go inventing behavior, bestie, iykyk π
