Intel accelerates Linux software development with support for Arrow Lake and Lunar Lake

author:IT House

IT Home reported on December 17 that Intel submitted the first drm-xe-next Pull Reques before the Linux 6.8 merger, replacing the traditional i915 DRM kernel driver on Linux with the latest Xe GPU driver.

In fact, Intel has supported Xe experimental features since Tiger Lake, but given that the i915 is still the dominant driver for the Meteor Lake and Alchemist platforms, Intel's goal should be to make this Intel Xe driver the primary driver for Lunar Lake and beyond.

IT Home has summarized all the changes that Intel has added to the Xe2 (Battlemage) GPU as follows:

  • drm/xe: Add performance tuning settings for MTL and Xe2:添加针对 MTL 和 Xe2 的性能调优设置
  • drm / xe / xe2: Add MOCS table:添加 MOCS 表
  • drm / xe / xe2: Respond to TRTT faults as unsuccessful page fault:将 TRTT 故障响应为不成功的页面故障
  • drm / xe / xe2: Add initial workarounds:添加初始的解决方法
  • drm / xe / xe2: Set tile y type in XY_FAST_COPY_BLT to Tile4:在 XY_FAST_COPY_BLT 中设置 tile y 类型为 Tile4
  • drm / xe / xe2: Update MOCS fields in blitter instructions:更新 blitter 指令中的 MOCS 字段
  • drm / xe / xe2: Determine bios enablement for flat ccs on igfx:确定 igfx 上 flat ccs 的 BIOS 启用状态
  • drm / xe / xe2: Modify main memory to ccs memory ratio:修改主内存与 CCS 内存的比例
  • drm / xe / xe2: Allocate extra pages for ccs during bo create:在 bo 创建期间为 CCS 分配额外的页面
  • drm / xe / xe2: Updates on XY_CTRL_SURF_COPY_BLT: Updates on XY_CTRL_SURF_COPY_BLT
  • drm / xe / xe2: Update chunk size for each iteration of ccs copy:更新 CCS 复制的每次迭代的块大小
  • drm / xe / xe2: Update emit_pte to use compression enabled PAT index:更新 emit_pte 以使用启用了压缩的 PAT 索引
  • drm / xe / xe2: Handle flat ccs move for igfx:处理 igfx 上的 flat ccs 移动操作。
  • drm / xe / xe2: Modify xe_bo_test for system memory:修改 xe_bo_test 以适应系统内存。
  • drm / xe / xe2: Support flat ccs:支持 flat ccs。
  • drm / xe / xe2: Extend reserved stolen sizes:扩展保留的占用大小。
  • drm / xe / xe2: Add missing mocs entry:添加缺失的 mocs 条目。
  • drm / xe / xe2: Follow XeHPC for TLB invalidation:遵循 XeHPC 进行 TLB 无效化。
  • drm / xe / xe2: Add one more bit to encode PAT to ppgtt entries:向 PAT 到 ppgtt 条目的编码中添加一个额外的 bit。
  • drm / xe / pat: Add debugfs node to dump PAT:添加 debugfs 节点以转储 PAT。
  • drm / xe / xe2: Update render / compute context image sizes:更新渲染 / 计算上下文图像大小
  • drm / xe / xe2: Add GT topology readout:添加 GT 拓扑读出
  • drm / xe / xe2: Add MCR register steering for primary GT 添加主 GT 的 MCR 寄存器控制

  • drm / xe / xe2: Update context image layouts:更新上下文图像布局
  • drm / xe / xe2: Handle fused-off CCS engines:处理熔断的 CCS 引擎
  • drm / xe / xe2: uxCCS is no longer used:放弃使用 AuxCCS
  • drm/xe/xe2: Define Xe2_LPG IP features:定义 Xe2_LPG IP 功能
  • drm/xe/xe2: Define Xe2_LPM IP features:定义 Xe2_LPM IP 功能
  • drm / xe / xe2: Track VA bits independently of max page table level:独立于最大页表级别跟踪 VA 位
  • drm / xe / xe2: Program GuC's MOCS on Xe2 and beyond:在 Xe2 及更高版本上编程 GuC 的 MOCS
  • drm / xe / xe2: Program correct MOCS registers:为正确的 MOCS 寄存器编程
  • drm / xe / xe2: Update SVG state handling:更新 SVG 状态处理
  • DRM/vehicle/xe2: Program PAT tables:编程 PAT 表

In addition to the Xe graphics driver, Intel has also introduced support for next-generation products for existing software packages, such as Intel VC Intrinsics, which has received support for the Arrow Lake and Lunar Lake graphics architectures. This means that the Xe-LPG+ (Arrow Lake / Alchemist) and Xe2 (Lunar Lake / Battlemage) architectures have received support for the software, demonstrating Intel's commitment to Linux development.
