The values of all but the RADEON_HPD_NONE members of the radeon_hpd_id enum transform 1:1 into bit positions within the 'enabled' bitset as assembled by evergreen_hpd_init(): enabled |= 1 << radeon_connector->hpd.hpd; However, if ->hpd.hpd happens to equal RADEON_HPD_NONE == 0xff, UBSAN reports UBSAN: Undefined behaviour in drivers/gpu/drm/radeon/evergreen.c:1867:16 shift exponent 255 is too large for 32-bit type 'int' [...] Call Trace: [<ffffffff818c4d35>] dump_stack+0xbc/0x117 [<ffffffff818c4c79>] ? _atomic_dec_and_lock+0x169/0x169 [<ffffffff819411bb>] ubsan_epilogue+0xd/0x4e [<ffffffff81941cbc>] __ubsan_handle_shift_out_of_bounds+0x1fb/0x254 [<ffffffffa0ba7f2e>] ? atom_execute_table+0x3e/0x50 [radeon] [<ffffffff81941ac1>] ? __ubsan_handle_load_invalid_value+0x158/0x158 [<ffffffffa0b87700>] ? radeon_get_pll_use_mask+0x130/0x130 [radeon] [<ffffffff81219930>] ? wake_up_klogd_work_func+0x60/0x60 [<ffffffff8121a35e>] ? vprintk_default+0x3e/0x60 [<ffffffffa0c603c4>] evergreen_hpd_init+0x274/0x2d0 [radeon] [<ffffffffa0c603c4>] ? evergreen_hpd_init+0x274/0x2d0 [radeon] [<ffffffffa0bd196e>] radeon_modeset_init+0x8ce/0x18d0 [radeon] [<ffffffffa0b71d86>] radeon_driver_load_kms+0x186/0x350 [radeon] [<ffffffffa03b6b16>] drm_dev_register+0xc6/0x100 [drm] [<ffffffffa03bc8c4>] drm_get_pci_dev+0xe4/0x490 [drm] [<ffffffff814b83f0>] ? kfree+0x220/0x370 [<ffffffffa0b687c2>] radeon_pci_probe+0x112/0x140 [radeon] [...] ===================================================================== radeon 0000:01:00.0: No connectors reported connected with modes At least on x86, there should be no user-visible impact as there 1 << 0xff == 1 << (0xff & 31) == 1 << 31 holds and 31 > RADEON_MAX_HPD_PINS. Thus, this patch is a cosmetic one. All of the above applies analogously to evergreen_hpd_fini(), r100_hpd_init(), r100_hpd_fini(), r600_hpd_init(), r600_hpd_fini(), rs600_hpd_init() and rs600_hpd_fini() Silence UBSAN by checking ->hpd.hpd for RADEON_HPD_NONE before oring it into the 'enabled' bitset in the *_init()- or the 'disabled' bitset in the *_fini()-functions respectively.
