            Bug ID: 1626
           Summary: HPET timers do not work on the Osage customer
                    reference platform
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: eventdev
          Assignee: dev at dpdk.org
          Reporter: nandinipersad361 at gmail.com
  Target Milestone: ---

HPET timers do not work on the Osage customer reference platform which includes
an Intel® Xeon® processor 5500 series processor) using the released BIOS from
Intel.

Implication:
On Osage boards, the implementation of the rte_delay_us() function must be
changed to not use the HPET timer.

Resolution/Workaround:
This can be addressed by building the system with RTE_LIBEAL_USE_HPET unset or
by using the --no-hpet EAL option.

Affected Environment/Platform:
The Osage customer reference platform. Other vendor platforms with Intel® Xeon®
processor 5500 series processors should work correctly, provided the BIOS
supports HPET.

Driver/Module:
lib/eal/include/rte_cycles.h
