[PATCH 4/4] kunit: tool: Disable broken options for --alltests

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There are a number of Kconfig options which break compilation under UML with
allyesconfig.  As kunit_tool's --alltests option is based on allyesconfig and
UML, we need to update the list of broken options to make --alltests build
again.

Note that, while this does build again, it still segfaults on startup,
so more work remains to be done.

They are:
- CONFIG_VFIO_PCI: Needs ioport_map/ioport_unmap.
- CONFIG_INFINIBAND_RDMAVT: Needs cpuinfo_x86 and __copy_user_nocache
- CONFIG_BNXT: Failing under UML with -Werror
ERROR:root:../drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c: In function ‘bnxt_ptp_enable’:
../drivers/net/ethernet/broadcom/bnxt/bnxt_ptp.c:400:43: error: array subscript 255 is above array bounds of ‘struct pps_pin[4]’ [-Werror=array-bounds]
  400 |                         ptp->pps_info.pins[pin_id].event = BNXT_PPS_EVENT_EXTERNAL;
      |                         ~~~~~~~~~~~~~~~~~~^~~~~~~~
- CONFIG_PATA_CS5535: Needs MSR access (__tracepoint_{read,write}_msr)
- CONFIG_VDPA: Enables CONFIG_DMA_OPS, which is unimplemented. ('dma_ops' is not defined)

These are all issues which should be investigated properly and the
corresponding options either fixed or disabled under UML. Having this
list of broken options should act as a good to-do list here, and will
allow these issues to be worked on independently, and other tests to
work in the meantime.
