In orderto ensure that each one of these sets the corresponding Kconfig symbols,change over the PAGE_SHIFT definition to the common one and allowonly the hardware page size to be selected.Acked-by: Guo Ren Acked-by: Heiko Carstens Acked-by: Stafford Horne Acked-by: Johannes Berg Acked-by: Geert Uytterhoeven Reviewed-by: Thomas Gleixner Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/microblaze/Kconfig

fcbfe812 - Kconfig: introduce HAS_IOPORT option and select it as necessary

Thu, 23 Mar 2023 16:33:52 +0000

Kconfig: introduce HAS_IOPORT option and select it as necessaryWe introduce a new HAS_IOPORT Kconfig option to indicate support for I/OPort access. In a future patch HAS_IOPORT=n will disable compilation ofthe I/O accessor functions inb()/outb() and friends on architectureswhich can not meaningfully support legacy I/O spaces such as s390.The following architectures do not select HAS_IOPORT:* ARC* C-SKY* Hexagon* Nios II* OpenRISC* s390* User-Mode Linux* XtensaAll other architectures select HAS_IOPORT at least conditionally.The "depends on" relations on HAS_IOPORT in drivers as well as ifdefsfor HAS_IOPORT specific sections will be added in subsequent patches ona per subsystem basis.Co-developed-by: Arnd Bergmann Signed-off-by: Arnd Bergmann Acked-by: Johannes Berg # for ARCH=umAcked-by: Geert Uytterhoeven Signed-off-by: Niklas Schnelle Signed-off-by: Arnd Bergmann List of files: /linux-6.15/arch/microblaze/Kconfig

a5e3aaa6 - microblaze: Add xmb_manager_register function

Mon, 27 Jun 2022 06:40:22 +0000

microblaze: Add xmb_manager_register functionTriple Modular Redundancy (TMR) Microblaze solution provides soft errorinjection, detection, correction and recovery for Microblaze cores in thesystem. The Xilinx/AMD Triple Modular Redundancy (TMR) solution in Vivadoprovides all the necessary building blocks to implement a redundanttriplicated MicroBlaze subsystem. This processing subsystem isfault-tolerant and continues to operate nominally after encountering anerror. Together with the capability to detect and recover from errors,the implementation ensures the reliability of the entire subsystem.When the break vector gets asserted because of error injection,the break signal must be blocked before exiting from the break handler,This commit adds support for xmb_manager_register api which updates theTMR manager address and control register and error count and reset callbackfunction arguments, which will be used by the break handler to block thebreak and call the error count callback function and reset callbackfunction.Signed-off-by: Appana Durga Kedareswara rao Link: https://lore.kernel.org/r/20220627064024.771037-2-appana.durga.rao@xilinx.comSigned-off-by: Michal Simek List of files: /linux-6.15/arch/microblaze/Kconfig

Mon, 23 May 2022 19:59:02 +0000

arch/*/: remove CONFIG_VIRT_TO_BUSAll architecture-independent users of virt_to_bus() and bus_to_virt()have been fixed to use the dma mapping interfaces or have beenremoved now. This means the definitions on most architectures, and theCONFIG_VIRT_TO_BUS symbol are now obsolete and can be removed.The only exceptions to this are a few network and scsi drivers for m68kAmiga and VME machines and ppc32 Macintosh. These drivers work correctlywith the old interfaces and are probably not worth changing.On alpha and parisc, virt_to_bus() were still used in asm/floppy.h.alpha can use isa_virt_to_bus() like x86 does, and parisc can justopen-code the virt_to_phys() here, as this is architecture specificcode.I tried updating the bus-virt-phys-mapping.rst documentation, whichstarted as an email from Linus to explain some details of the Linux-2.0driver interfaces. The bits about virt_to_bus() were declared obsoletebackin 2000, and the rest is not all that relevant any more, so in theend I just decided to remove the file completely.Reviewed-by: Geert Uytterhoeven Acked-by: Geert Uytterhoeven Acked-by: Michael Ellerman (powerpc)Acked-by: Helge Deller # pariscSigned-off-by: Arnd Bergmann List of files: /linux-6.15/arch/microblaze/Kconfig
