From: Lionel Landwerlin <lionel.g.landwerlin@intel.com>
Verify that the per-context dynamic SSEU uAPI works as expected.
v2: Add subslice tests (Lionel)
Use MI_SET_PREDICATE for further verification when available (Lionel)
v3: Rename to gem_ctx_rpcs (Lionel)
v4: Update kernel API (Lionel)
Add 0 value test (Lionel)
Exercise invalid values (Lionel)
v5: Add perf tests (Lionel)
v6: Add new sysfs entry tests (Lionel)
v7: Test rsvd fields
Update for kernel series changes
v8: Drop test_no_sseu_support() test (Kelvin)
Drop drm_intel_*() apis (Chris)
v9: by Chris:
Drop all do_ioctl/do_ioctl_err()
Use gem_context_[gs]et_param()
Use gem_read() instead of mapping memory
by Lionel:
Test dynamic sseu on/off more
Tvrtko Ursulin:
v10:
* Various style tweaks and refactorings.
* New test coverage.
v11:
* Change platform support to just Gen11.
* Simplify availability test. (Chris Wilson)
* More invalid pointer tests. (Chris Wilson)
v12:
* Fix MAP_FIXED use (doh!).
* Fix get/set copy&paste errors.
* Drop supported platform test. (Chris Wilson)
* Add mmap__gtt test. (Chris Wilson)
v13:
* Commit message tweaks.
* Added reset/hang/suspend tests. (Chris Wilson)
* Assert spinner is busy. (Chris Wilson)
* Remove some more ABI assumptions. (Chris Wilson)
v14:
* Use default resume time. (Chris Wilson)
* Trigger hang after rpcs read batch has been submitted. (Chris Wilson)
v15:
* Adjust for uAPI restrictions.
v16:
* Build system changes.
v17:
* Remove all subtests which read the RPCS register. (Joonas Lahtinen)
v18:
* Tidy curly braces. (Joonas Lahtinen)
v19:
* Check flags/rsvd MBZ.

3 siblings, 1 reply; 12+ messages in thread
From: Tvrtko Ursulin @ 2019-01-08 15:13 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx
From: Tony Ye <tony.ye@intel.com>
Simple test which exercises the VME fixed function block.
v2: (Tvrtko Ursulin)
* Small cleanups like copyright date, tabs, remove unused bits.
v3: (Tony Ye)
* Added curbe data entry for dst surface.
* Read the dst surface after the VME kernel being executed.
v4: (Tony Ye)
* Added the media_vme.gxa kernel source code and compile instructions.
v5: (Tvrtko Ursulin)
* Added hang detector.
v6: (Tvrtko Ursulin)
* Replace gem_read with gem_sync. (Chris Wilson)

+Step1: Building IGA (Intel Graphics Assembler)
+========================================================================
+
+1. Download or clone IGC (Intel Graphics Compiler)
+
+ https://github.com/intel/intel-graphics-compiler.git
+
+2. Chdir into 'intel-graphics-compiler' (or any other workspace folder of choice)
+
+ It should read the following folder strucutre:
+
+ workspace
+ |- visa
+ |- IGC
+ |- inc
+ |- 3d
+ |- skuwa
+
+3. Chdir into IGA sub-component
+
+ cd visa/iga
+
+4. Create build directory
+
+ mkdir build
+
+5. Change into build directory
+
+ cd build
+
+6. Run cmake
+
+ cmake ../
+
+7. Run make to build IGA project
+
+ make
+
+8. Get the output executable "iga64" in IGAExe folder
+
+ usage: ./iga64 OPTIONS ARGS
+ where OPTIONS:
+ -h --help shows help on an option
+ -d --disassemble disassembles the input file
+ -a --assemble assembles the input file
+ -n --numeric-labels use numeric labels
+ -p --platform DEVICE specifies the platform (e.g. "GEN9")
+ -o --output FILE specifies the output file
+
+ EXAMPLES:
+ ./iga64 file.gxa -p=11 -a -o file.krn
+
+Step2: Building ASM code
+========================================================================
+1. Command line to convert asm code to binary:
+
+ iga64 media_vme.gxa -p=11 -a -o media_vme.krn
+
+2. Pad 128 bytes zeros to the kernel:
+
+ dd if=/dev/zero bs=1 count=128 >> media_vme.krn
+
+3. Generate hexdump:
+
+ hexdump -v -e '4/4 "0x%08x " "\n"' media_vme.krn > media_vme.hex
