fsl_upm_start_pattern(9)

💅 fsl_upm_start_pattern(9) — Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, section 9 of the Kernel API Manual, and you need the UPM to actually do something. That's literally this function. Let's go ✨

🌸 NAME

fsl_upm_start_pattern — start UPM patterns execution 🎬

✨ SYNOPSIS

void fsl_upm_start_pattern (struct fsl_upm *upm , u8 pat_offset );

🎀 ARGUMENTS

• upm — pointer to the fsl_upm structure, and you get that bad boy via fsl_upm_find. iykyk 🫶
• pat_offset — the UPM pattern offset for the command that's about to be executed. it's a u8, so keep it cute and small 💅

🦋 DESCRIPTION

This routine programmes UPM so that the next memory access that hits an UPM will trigger pattern execution, starting right at pat_offset. so basically: you set it up, and the very next access is the main character 👑

not me hyping up a memory access but here we are 🔥

🔥 SEE ALSO

• Kernel file ./arch/powerpc/include/asm/fsl_lbc.h
• fsl_upm_end_pattern(9)

(they're a matching set, bestie — start it, then end it 🎀)
