SAI 9.x requires a SYNCD_SHM_SIZE specified otherwise it will default to 64mb which is insufficient for syncd.
E.G. of a few failures seen when insufficient shmem was set
ha_init: The file: warmboot_data_0 is of size=762[MB] and is beyond the directory: /dev/shm available storage of size=64[MB]#015
syncd.sh[26074]: Cannot get SYNCD_SHM_SIZE for chip: [869] in /usr/share/sonic/device/x86_64-broadcom_common/syncd_shm.ini. Skip set SYNCD_SHM_SIZE.
Syncd hangs here:
syncd#syncd: [none] SAI_API_SWITCH:_brcm_sai_shr_ha_section_resize:536 start=0x7f6e641b4000, end=0x7f6e645b4000, len=302276608, free=0x7f6e641b4000
Broadcom recommended using 1gb for DNX devices.
Since currently we don't use SAI9.x on master and 202305 this change won't fix anything until we upgrade the SAI on those branches.
Introduce new sonic-buildimage images for Broadcom DNX ASIC family.
sonic-broadcom-dnx.bin
sonic-aboot-broadcom-dnx.swi
How I did it
NO CHANGE to existing make commands
make init; make configure PLATFORM=broadcom; make target/sonic-aboot-broadcom.swi; make target/sonic-broadcom.bin
The difference now is that it will result in new broadcom images for DNX asic family as well.
sonic-broadcom.bin, sonic-broadcom-dnx.bin
sonic-aboot-broadcom.swi, sonic-aboot-broadcom-dnx.swi
Note: This PR also adds support for Broadcom SAI 5.0 (based on 1.8 SAI ) for DNX based platform + changes in platform x86_64-arista_7280cr3_32p4 bcm config files and platform_env.conf files
