panthor_fw_conv_timeout(9)

💖 NAME 💖

okay so this is panthor_fw_conv_timeout(9) from the Kernel API Manual, and its whole personality is convert a timeout into a cycle-count. literally that's the job, bestie 💅✨

✨ SYNOPSIS ✨

u32 panthor_fw_conv_timeout (struct panthor_device *ptdev , u32
       timeout_us );

🎀 ARGUMENTS 🎀

• ptdev — Device. the device in question, no cap 🫶
• timeout_us — Timeout expressed in micro-seconds. yes, micro-seconds, keep that unit bestie ⏱️

🦋 DESCRIPTION 🦋

The FW has two timer sources: the GPU counter or arch-timer. that's the vibe check 🕰️

We need to express timeouts in term of number of cycles and specify which timer source should be used. iykyk, it's giving “timeout but make it cycle-count” 🔥

🌸 RETURN 🌸

A value suitable for timeout fields in the global interface. periodt 💅✨
