I whakaaetia e Linus Torvalds te kernel Linux Ko te putanga 7.1, e tūmanakohia ana kia tukuna i waenganui o Hune, e whakaatu ana i te raupapa tuatahi o ngā huringa hei tango i te tautoko mō ngā tukatuka i486. I tēnei wā, kua tangohia ngā kōwhiringa mō te hanga i te kernel me te tautoko mō ngā tukatuka 486DX, 486SX, me AMD ELAN (CONFIG_M486, CONFIG_M486SX, me CONFIG_MELAN) mai i Kconfig, ā, kua tangohia ngā kōwhiringa whakahiato mō ngā pūnaha i486 i te Makefile (-march=i486). Kei roto tonu te waehere tūturu mō te tautoko i ngā tukatuka i486 i roto i te kernel, engari ko te hanga mō ēnei pūnaha me whai papaki ki ngā makefile.
Ko ngā take mō te tango i te tautoko mō ngā tukatuka i486 e pā ana ki te hiahia ki te pupuri i te waehere kernel uaua e whai ana i ētahi mahi taputapu, pērā i te CX8 (whakatairite me te whakawhiti i te 8 paita) me te TSC (te kaute huringa CPU e whakamahia ana i roto i te kaiwhakarite mahi). I ētahi wā ka puta he raruraru i tēnei waehere, ā, ko te rapu raruraru ka moumou i te wā o ngā kaiwhakawhanake ka taea te whakapau kaha ake. I taua wā, he iti noa te hunga e whakamahi ana i ngā peka kernel hou. Linux i runga i ngā CPU 32-bit tawhito, kāore he tohatoha nui e toe ana hei whakaputa tonu i ngā mōkihi kernel i whakahiatohia me te kōwhiringa "M486=y".
I ngā wā o mua, i whakaarahia te take o te tango i te tautoko mō te PTM i486 e ngā kaiwhakawhanake kernel. Linux Kia rua pea ngā wā. I te marama o Oketopa 2022, i whakaarahia e Linus Torvalds te take mō te tango i te tautoko CPU i486, me te matapaki i tētahi take i puta mai i tētahi hapa i roto i te waehere whakatauira tohutohu CX8. I kite a Linus kua riro ngā tukatuka i486 hei taonga whare taonga, ā, ka taea te whakamahi ngāwari i ngā matua "whare taonga". I te tau 2025, i muri i te kitenga o tētahi atu take e pā ana ki te whakatauira tohutohu CX8, ka tīmata anō te kōrero, ā, i kī a Linus Torvalds kua tae ki te wā ki te tango i te tautoko mō ngā CPU i486, ā, kāore ia i kite i tētahi take hei moumou taima tonu mā ngā kaiwhakawhanake ki te aro atu ki ngā take e puta mai ana i ēnei tukatuka.
I tangohia te tautoko mō ngā tukatuka i386 mai i te kernel i te tau 2012. E kore te tangohanga o te tautoko mō ngā tukatuka i486 tawhito e pā ki ngā tukatuka Intel Quark kua whakauruhia i hangaia i mua i te tau 2019, me ngā SoC Vortex86DX kei te hangaia tonutia, nā te mea ahakoa nō te akomanga i486 ēnei tukatuka, kei roto ko ngā tohutohu tāpiri e hāngai ana ki te whakatupuranga Pentium, tae atu ki te "cmpxchg8b."
