disable intel_lmce which not supported by virtual machines unsupported lmce/mce causing crash-dump during virtual machine boot as well reboot and shutdown scenarios. since lmce is not exposed to guest-os. hence disabled using kernel command line option. Updated kernel command line to disable local machine check exception and WAITPKG feature to address civ boot issue. applicable to all civ kernels crashdump: ========= [ 0.205755] ------------[ cut here ]------------ [ 0.206454] WARNING: CPU: 0 PID: 0 at arch/x86/kernel/cpu/mce/intel.c:124 intel_init_lmce+0xe9/0xf0 [ 0.207454] Modules linked in: [ 0.208454] CPU: 0 PID: 0 Comm: swapper/0 Tainted: G U 5.15.74-ga0db5462ba8a-dirty #1 [ 0.209454] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 [ 0.210454] RIP: 0010:intel_init_lmce+0xe9/0xf0 [ 0.211057] Code: 48 c1 eb 20 b9 d0 04 00 00 89 da 0f 30 83 3d 45 5f 5b 03 00 7e 0f bf d0 04 00 00 48 89 c6 31 d2 b [ 0.211454] RSP: 0000:ffffffff8c403dd0 EFLAGS: 00010246 [ 0.212454] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 000000000000003a [ 0.213454] RDX: 0000000000000000 RSI: ffffffff89122d28 RDI: 0000000000000030 [ 0.214454] RBP: ffffffff8c403de0 R08: ffffffff8c4149a8 R09: ffff9a738044cfff [ 0.215416] R10: ffff8bcf401c4018 R11: ffffffff8a35b480 R12: 000000000000000a [ 0.215454] R13: ffffffff8c6e5210 R14: ffffffff8c6e5198 R15: ffffffff8c6e5198 [ 0.216454] FS: 0000000000000000(0000) GS:ffff8bcfbbc00000(0000) knlGS:0000000000000000 [ 0.217454] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 0.218454] CR2: ffff8bcfa9001000 CR3: 0000000168414001 CR4: 0000000000770ef0 [ 0.219455] PKRU: 55555554 [ 0.220454] Call Trace: [ 0.220787] <TASK> [ 0.221073] mce_intel_feature_init+0x1d/0x190 [ 0.221454] __mcheck_cpu_init_vendor+0x24/0xb0 [ 0.222061] mcheck_cpu_init+0x380/0x4d0 [ 0.222454] ? bsp_init_amd.a37caec6941172bae46ab451b1d4de9c.cfi_jt+0x8/0x8 [ 0.223454] identify_cpu+0x67f/0x740 [ 0.223948] identify_boot_cpu+0x11/0xbc [ 0.224454] check_bugs+0x20/0xfe [ 0.224902] start_kernel+0x454/0x4f9 [ 0.225454] x86_64_start_reservations+0x24/0x26 [ 0.226454] x86_64_start_kernel+0x58/0x5b [ 0.227007] secondary_startup_64_no_verify+0xb1/0xbb [ 0.227454] </TASK> [ 0.227752] ---[ end trace d412e29ab214f46e ]--- Tracked-On: OAM-104891 Mixin-Reviewed-On: projectceladon/device-androidia-mixins#1538 Signed-off-by: rajucm <raju.mallikarjun.chegaraddi@intel.com>
