Implement a ligth weight device driver test framework, KDDV(Kernel
Device Driver Verification). Which using eBPF based bus controllers
to mockup device chipsets.

The kddv already discover the following issues:
  fc92d9e3de0b iio: health: afe4404: Fix oob read in afe4404_[read|write]_raw
  58143c1ed588 iio: health: afe4403: Fix oob read in afe4403_read_raw
  3f4033a811bc iio: filter: admv8818: close potential out-of-bounds read in __admv8818_read_[h|l]pf_freq()
  8c9a59939deb Input: raydium_ts_i2c - fix memory leak in raydium_i2c_send()
  7485edb2b6ca media: i2c: ov772x: Fix memleak in ov772x_probe()
  bab76514aca3 regulator: da9121: Fix uninit-value in da9121_assign_chip_model()
  9d47e01b9d80 power: supply: adp5061: fix out-of-bounds read in adp5061_get_chg_type()
  ...

Zhang Xiaoxu (14):
  kddv/core: Implement a ligth weight device driver test framework
  kddv/core: Allow test case config bpf program
  kddv/core: Add io fault support to bpf program
  kddv/core: Check kmsg before return from test case
  kddv/core: Support kernel memory leak detector
  kddv/core: Add page and slab fault inject support
  kddv/cmd: Add command to create/remove mockup device
  kddv/cmd: Add command to run testcases
  kddv/core: Add test support for SPI driver
  kddv/tests: Add support for testing hwmon driver
  kddv/tests/hwmon: Add test cases for max31722 driver
  kddv/tests: Add support for testing mtd driver
  kddv/tests/mtd: Add test cases for mchp23k256 driver
  kddv: Add document for kddv
