π nvkm_gsp_mem_ctor(9) β bestie edition π
okay so you're reading the Kernel API Manual page for nvkm_gsp_mem_ctor, and honestly? it's giving "small function, big responsibility" energy. let's get into it π«Ά
β¨ NAME β¨
nvkm_gsp_mem_ctor β the constructor for nvkm_gsp_mem objects. literally what it says on the tin, no cap.
πΈ SYNOPSIS πΈ
int nvkm_gsp_mem_ctor (struct nvkm_gsp *gsp , size_t size , struct
nvkm_gsp_mem *mem );
π ARGUMENTS π
gspβ the gsp pointer. yes. that's the whole description. iconic of the kernel docs tbh πsizeβ the number of bytes to allocate. you know. the size. the bigness. the amount of memory we're asking for πmemβ thenvkm_gsp_memobject you want initialized. this is the glow-up recipient β¨
π¦ DESCRIPTION π¦
so what does it actually do? it allocates a block of memory for use with GSP. that's the whole job, and it does it well π
here's the part you actually need to remember tho β this memory block can potentially out-live the driver's remove callback, so we take a device reference to make sure its lifetime is safe and nobody yanks the rug out from under it. that reference gets dropped in the destructor (not here, bestie β the destructor's job, not the constructor's). so like, yes this is a constructor but it's also doing a little lifetime-babysitting. main character energy fr fr π
ngl this is the classic "object survives longer than you'd think" situation β the reference is your seatbelt, don't sleep on it π

like. that is a whole friend group of functions and structs, go say hi to them too π§

this lil page lives over at ./drivers/gpu/drm/nouveau/nvkm... and it's dated October 2026 β yeah, from the future, idk what to tell you π happy nvkm_gsp_mem_ctor-ing, bestie, go allocate responsibly πππ₯
