STRUCT HL_INFO_DEV_MEMALLOC_PAGE_SIZES(9)

💅 NAME 💅

ok so bestie, gather round — struct hl_info_dev_memalloc_page_sizes is literally the struct that tells you which page sizes are valid in device mem alloc information. that's it, that's the vibe ✨

🎀 SYNOPSIS 🎀

struct hl_info_dev_memalloc_page_sizes {
    __u64 page_order_bitmask;
};

🦋 Members 🦋

• page_order_bitmask — a bitmap, and every set bit is the order of a supported page size. so like, 0x2100000 means the 1MB and 32MB pages are supported. that's the whole flex 🫶

🌈 SEE ALSO 🌈

first up, the kernel file this whole thing lives in: ./include/uapi/drm/habanalabs_accel.h — go say hi 👑

then the rest of the friend group:

• enum hl_goya_dma_direction(9)
• enum hl_device_status(9)
• struct hl_info_hw_ip_info(9)
• struct hl_info_pci_counters(9)
• struct hl_info_clk_throttle(9)
• struct hl_info_energy(9)
• struct hl_open_stats_info(9)

• struct hl_info_engine_err_event(9)
• struct hl_page_fault_info(9)
• struct hl_user_mapping(9)

ngl this one's short and sweet — one member, one bitmask, zero drama. not me being obsessed with a struct that fits in a single field 😭💖

ok bye ily, this page lives in ./include/uapi/drm and the version/date situation is serving October 2026 🗓️✨ slay, periodt 💅🌸
