Hi, I was trying to build the Linux UEFI Validation (LUV) image for 32 bit systems. The LUV image incorporates the CHIPSEC test suite as well. I get the following warnings and errors during build time: ------------------------------------------------------------------------------------------------------------ CC [M] /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.o /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c: In function 'patch_apply_ucode': /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c:573:14: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] ucode_start=(unsigned long long) ucode_buf; ^ /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c: In function 'd_ioctl': /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c:946:3: warning: right shift count >= width of type ptr[1] = (uint32_t)(dtr.base >> 32); ^ /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c:1365:17: warning: left shift count >= width of type ptr[0] = first | (second << 32); ^ /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c:1405:17: warning: right shift count >= width of type iowrite32( ( value >> 32 ) & 0xFFFFFFFF, ioaddr ); ^ /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec_km.c:951:10: warning: 'dt_pa.u.high' may be used uninitialized in this function [-Wmaybe-uninitialized] ptr[3] = dt_pa.u.high; ^ LD [M] /home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec.o i586-oe-linux-ld.bfd: i386:x86-64 architecture of input file `/home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/amd64/cpu.o' is incompatible with i386 output make[3]: *** [/home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux/chipsec.o] Error 1 make[2]: *** [_module_/home/megha/luv_new/build/tmp/work/qemux86-oe-linux/chipsec/git-r0/git/source/drivers/linux] Error 2 make[2]: Leaving directory `/home/megha/luv_new/build/tmp/work-shared/qemux86/kernel-build-artifacts' make[1]: *** [sub-make] Error 2 make[1]: Leaving directory `/home/megha/luv_new/build/tmp/work-shared/qemux86/kernel-source' make: *** [chipsec] Error 2 ------------------------------------------------------------------------------------------------------------------------ I wanted to know if the CHIPSEC test suite builds and runs on 32 bit platforms? (in which case there is a problem with the CHIPSEC recipe in LUV). Else, any pointers as to why I see these warnings and errors? Any help would be appreciated!! Thanks, Megha
