          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal

         Component: ethdev
          Assignee: [email protected]

Target Milestone: ---

Doing LTO release build detects errors in irq

../drivers/common/cnxk/roc_platform.c: In function ‘irq_config’:
../drivers/common/cnxk/roc_platform.c:56:14: warning: argument to variable-length array is too large [-Wvla-larger-than=]
56 | char irq_set_buf[MSIX_IRQ_SET_BUF_LEN];
| ^
../drivers/common/cnxk/roc_platform.c:56:14: note: limit is 9223372036854775807 bytes, but argument is 18446744073709551548 ../drivers/common/cnxk/roc_platform.c: In function ‘irq_init’:
../drivers/common/cnxk/roc_platform.c:92:14: warning: argument to variable-length array is too large [-Wvla-larger-than=]

Looks like MSIX_IRQ_SET_BUF_LEN is not a constant??
