vmw_resource_unreserve(9)

💖 NAME 💖

okay so bestie, this is vmw_resource_unreserve(9) from the Kernel API Manual — it unreserves a resource that was previously reserved for command submission. literally that's the whole name, no cap. 🫶

✨ SYNOPSIS ✨

void vmw_resource_unreserve (struct vmw_resource *res , bool dirty_set , bool dirty , bool switch_guest_memory , struct vmw_bo *new_guest_memory_bo , unsigned long new_guest_memory_offset );

that signature is giving "long but iconic" 💅

🎀 ARGUMENTS 🎀

• res — pointer to the struct vmw_resource you're gonna unreserve. main character energy.
• dirty_set — change the dirty status of the resource. yes ma'am.
• dirty — when you're changing dirty status, this indicates the new status. noted ✨
• switch_guest_memory — the guest memory buffer has been switched. slay.
• new_guest_memory_bo — pointer to the new guest memory buffer if command submission switched. it may be NULL. 🫶
• new_guest_memory_offset — the new gbo offset if switch_guest_memory is true. periodt.

🦋 DESCRIPTION 🦋

currently, unreserving a resource means putting it back on the device's resource lru list, so that it can be evicted if necessary. lowkey simple, highkey the whole vibe rn. 💖
