Those have been receiving just drive-by updates and no one really uses them. At least there are no traces of usage on the mailing lists. So, with the advent of AI-generated fixes frenzy, and because no one can really test fixes on those, it is time to sunset them and point them towards the eternal happy hunting-grounds - Add a dummy EDAC driver with which the EDAC core glue can be exercised in a VM for the cases where one does not necessarily have access to the hardware. This glue should be extended with all the necessary functionality that needs and can be tested this way - Add an EDAC driver to reset bitfix filters in Intel hardware. Bitfix filters are a hw mechanism for tracking stuck bits in memory and CPU arrays due to, e.g., silicon aging. Those filters can become clogged by transient errors accumulating over a long system uptime so this intel-bff (LOL :)) driver glue resets those filters on overflow. Work by Qiuxu Zhuo and Tony Luck - Export get_cpu_cacheinfo_id() for use by the new intel-bff driver - i10nm: Handle the case where hw disables memory controllers which leads to reporting the wrong memory controller when reporting an error - The now-usual AI-powered fixes and other misc cleanups and updates all over the place* tag 'edac_updates_for_v7.4_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras: MAINTAINERS: Orphan drivers/edac/i3200_edac.c EDAC/skx_base: Fix ambiguous bitwise and logical operator style EDAC/i10nm: Fix mdev reference leak in i10nm_get_ddr_munits() MAINTAINERS: Orphan drivers/edac/xgene_edac.c MAINTAINERS: Orphan drivers/edac/x38_edac.c MAINTAINERS: Orphan drivers/edac/i82975x_edac.c EDAC/dummy: Add a dummy EDAC driver EDAC/ie31200: Disable PCI device when probing fails EDAC/{bluefield,loongson}: Use named initializers for acpi_device_id MAINTAINERS: Update Qiuxu Zhuo's email address EDAC/intel-bff: Report frequent filter overflows EDAC/intel-bff: Compute unique ID for overflowed filter EDAC/intel-bff: Reset bitfix filter when it overflows EDAC/intel-bff: Add Diamond Rapids support EDAC/intel-bff: Add stub Intel bitfix filter driver x86/mce: Add enumeration for Intel bitfix filter reset cacheinfo: Export get_cpu_cacheinfo_id() for loadable modules EDAC/i10nm: Fix Granite Rapids ADXL MC mapping List of files: /linux/drivers/edac/dummy_edac.c Tue, 20 Oct 2026 20:14:43 +0200 Linus Torvalds <torvalds@linux-foundation.org> http://kernelsources.org:8080/source/history/linux/drivers/edac/dummy_edac.c#558c19e274efb75bd7bfb8cf9fe562c6497c9420 EDAC/dummy: Add a dummy EDAC driverA dummy EDAC driver is useful for testing purposes in a VM when onedoesn't have all the hardware needed to test aspects of the EDACsubsystem code.Fix edac/Makefile alignment while at it.Assisted-by: LLMSigned-off-by: Borislav Petkov (AMD) <bp@alien8.de>Link: https://patch.msgid.link/20260707215307.396571-1-bp@kernel.org List of files: /linux/drivers/edac/dummy_edac.c Tue, 07 Jul 2026 23:53:07 +0200 Borislav Petkov (AMD) <bp@alien8.de>
