π DALSMC_MSG_S...pSleepDcfclk(9) β a Kernel API Manual moment π
okay so bestie, welcome to the Kernel API Manual β¨ this one is a whole vibe: it's the page for DALSMC_MSG_S...pSleepDcfclk(9), and yes the title is doing the most with that truncation, we love her anyway π«Ά
πΈ NAME πΈ
DALSMC_MSG_SetMinDeepSleepDcfclk β sets the minimum DCFCLK frequency in deep sleep. that's it, that's the whole job, and honestly? iconic. no cap π
β¨ SYNOPSIS β¨
DALSMC_MSG_SetMinDeepSleepDcfclk
just the one line, she's lowkey mysterious like that π
π¦ DESCRIPTION π¦
okay so here's the tea β β this message is a request, and it carries exactly one thing:
- Request:
MinDcfclkMhzβ the minimum DCFCLK frequency in MHz during deep sleep π₯ like, the floor for how low the clock can go while everything's snoozing π΄ - Response: (none beyond result code) β yeah, she sends back literally nothing except the result code. no extra data, no little gift, just "k, done" energy π
no cap: the only thing coming back is the result code, so don't go looking for a payload, bestie π«Ά
