STRUCT AMDXDNA_DRM_VA_TBL(9)

💅 struct amdxdna_drm_va_tbl(9)

okay so bestie, welcome to the Kernel API Manual page for struct amdxdna_drm_va_tbl — yes that's a mouthful, yes it's from the kernel, and yes we're gonna get through it together 🫶

The NAME section is literally just the struct name, no fancy subtitle, no blurb, nothing. Iconic minimalism honestly. ✨

✨ SYNOPSIS ✨

Here's the whole struct, copy-paste-exact, don't touch a single character:

struct amdxdna_drm_va_tbl {
    __s32 dmabuf_fd;
    __u32 num_entries;
    struct amdxdna_drm_va_entry va_entries[];
 };

🎀 Members 🎀

• dmabuf_fd — the fd of dmabuf. that's it, that's the field 💅
• num_entries — number of va entries. a count, bestie, a humble little count 🔢
• va_entries — array of va entries. the flexible-array main character of the whole struct 👑

🌸 Description 🌸

Okay so the vibe here is: the input can be either a dmabuf fd or a virtual address entry table. Pick your fighter, not both. 🥊

⚠️ and here's the rule that actually matters: when dmabuf_fd is used, num_entries must be zero. that's a must, not a maybe, not a "if you feel like it" — zero. fr fr 🚨
