💅 gaudi2_ack_..._bits_errors(9)

ok so real talk, this is a page from the Kernel API Manual and it's lowkey one of those little functions that does a lot of quiet heavy lifting. bestie, listen: gaudi2_ack_protection_bits_errors is the girl that scans literally every block that has protection bits, and for every single protection error she finds? she shows you the appropriate error message and clears the error. she's not just flagging problems, she's fixing the vibe on the way out. iconic behavior honestly 🎀

✨ SYNOPSIS ✨

void gaudi2_ack_protection_bits_errors (struct hl_device *hdev );

no return value, no drama, just vibes and a void. 🦋

🫶 ARGUMENTS 🫶

• hdev — pointer to hl_device structure. yes, that's the one. that's the whole argument list. she's low maintenance like that 💅

🌸 DESCRIPTION 🌸

okay so here's the lore, and it's important so don't skip it:

All protection bits are 1 by default, which means not protected. that's the starting state, that's the baseline, that's the出厂 default ✨

So what you gotta do is set to 0 each bit that belongs to a protected register. one bit at a time, on purpose, for every register you actually wanna protect. no shortcuts, no "eh close enough" — the specific bit for the specific protected register, set to 0, periodt. 💀

the way that this function walks all the blocks with protection bits and, for every protection error it finds, prints the appropriate error message and then clears the error — that's the whole job and she does it flawlessly.

mwah, that's the page! brought to you with love from ./drivers/accel/habanalabs/gaudi2, dated October 2026, in the Kernel API Manual itself. go protect those registers bestie, and remember: 1 = not protected, 0 = protected. don't mix them up or it's giving unhinged 💖✨
