jpeg_v5_0_2_sw_fini(9)
π jpeg_v5_0_2_sw_fini β a kernel API manual page, bestie edition π
ok so real quick, this is a page from the Kernel API Manual (yes, the (9) section, we're in kernel-land now β¨) and it's about one tiny but iconic function: jpeg_v5_0_2_sw_fini. she's the cleanup queen of the JPEG block and honestly? she ate. let's get into it π«Ά
β¨ NAME β¨
jpeg_v5_0_2_sw_fini β the sw fini for the JPEG block, no cap π
πΈ SYNOPSIS πΈ
int jpeg_v5_0_2_sw_fini (struct amdgpu_ip_block *ip_block );
like, that's the whole signature. returns an int, takes one pointer. lowkey elegant.
π¦ ARGUMENTS π¦
ip_blockβ a pointer to theamdgpu_ip_blockfor this hw instance. that's it, that's the vibe. she just needs to know which hw instance's ip block we're talking about, and then she does her thing π
π₯ DESCRIPTION π₯
ok so what does she actually do? two things, and they're both important:
- JPEG suspend π΄
- free up sw allocation π§Ήβ¨
that's the whole description in the source but like, think about the energy of it: this is the teardown. the goodbye. the "ok bestie we're done here, let's put the software allocations back where we found them" moment. she's not dramatic about it, she just does the job.
fr fr, this is the counterpart to jpeg_v5_0_2_sw_init β one sets things up, this one takes them down. that's literally the whole personality π
