devm_rproc_alloc(9)
π devm_rproc_alloc(9) β like, the whole glow-up β¨
okay so this is a page from the Kernel API Manual (yes, the Kernel API Manual, the one that lives in your terminal and judges you), and today we're talking about devm_rproc_alloc. it's giving "resource-managed bestie" energy and honestly? obsessed. π«Ά
β¨ NAME β¨
devm_rproc_alloc β the resource-managed version of rproc_alloc(). literally the same thing but it cleans up after itself. main character behavior, no cap. π
πΈ SYNOPSIS πΈ
struct rproc * devm_rproc_alloc (struct device *dev , const char *name ,
const struct rproc_ops *ops , const char *firmware , int len );
look at that signature. five whole arguments. she's thriving. π
π¦ ARGUMENTS π¦
devβ the underlying device. the whole thing hangs off this one, so don't be weird about it.nameβ the name of this remote processor. give her a cute name, she deserves it πopsβ the platform-specific handlers (mainlystart/stop). this is where you tell her how to do the thing.firmwareβ the name of the firmware file to load. can beNULL, no pressure, she's flexible like that.lenβ the length of private data needed by the rproc driver, in bytes. bring a measuring tape bestie π
π DESCRIPTION π
so here's the tea: this function performs exactly like rproc_alloc, okay? like, same energy, same behavior. but β and this is the iconic part β the acquired rproc device will automatically be released on driver detach. β¨
you don't have to manually free it. the devm machinery handles it for you. it's giving "I got you, bestie" and honestly we should all aspire. π§
fr fr, this is the managed one. that's the whole point. don't come for her with manual cleanup, she doesn't need it.
π RETURN π
- a new rproc instance β slay, you got one π
- or
NULLon failure β π it happens, check your args

mwah π that's the page. source: ./drivers/remoteproc, dated October 2026, and it's devm_rproc_alloc(9) all the way down. go forth and let the devm handle it, bestie π
