e8deee4f - ARC: [hsdk]: Enable FPU_SAVE_RESTORE

Fri, 08 Jan 2021 21:46:55 +0000

63bcf87c - arc: plat-hsdk: fix kconfig dependency warning when !RESET_CONTROLLER

Mon, 14 Sep 2020 11:46:52 +0000

arc: plat-hsdk: fix kconfig dependency warning when !RESET_CONTROLLERWhen ARC_SOC_HSDK is enabled and RESET_CONTROLLER is disabled, it resultsin the following Kbuild warning:WARNING: unmet direct dependencies detected for RESET_HSDK Depends on [n]: RESET_CONTROLLER [=n] && HAS_IOMEM [=y] && (ARC_SOC_HSDK [=y] || COMPILE_TEST [=n]) Selected by [y]: - ARC_SOC_HSDK [=y] && ISA_ARCV2 [=y]The reason is that ARC_SOC_HSDK selects RESET_HSDK without depending on orselecting RESET_CONTROLLER while RESET_HSDK is subordinate toRESET_CONTROLLER.Honor the kconfig menu hierarchy to remove kconfig dependency warnings.Fixes: a528629dfd3b ("ARC: [plat-hsdk] select CONFIG_RESET_HSDK from Kconfig")Signed-off-by: Necip Fazil Yildiran Signed-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/plat-hsdk/Kconfig

e494239a - ARCv2: support manual regfile save on interrupts

Wed, 06 Jun 2018 17:20:37 +0000

ARCv2: support manual regfile save on interruptsThere's a hardware bug which affects the HSDK platform, triggered bymicro-ops for auto-saving regfile on taken interrupt. The workaround isto inhibit autosave.Signed-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/plat-hsdk/Kconfig

eb01d42a - PCI: consolidate PCI config entry in drivers/pci

Thu, 15 Nov 2018 19:05:32 +0000

PCI: consolidate PCI config entry in drivers/pciThere is no good reason to duplicate the PCI menu in every architecture.Instead provide a selectable HAVE_PCI symbol that indicates availabilityof PCI support, and a FORCE_PCI symbol to for PCI on and the handle therest in drivers/pci.Signed-off-by: Christoph Hellwig Reviewed-by: Palmer Dabbelt Acked-by: Max Filippov Acked-by: Thomas Gleixner Acked-by: Bjorn Helgaas Acked-by: Geert Uytterhoeven Acked-by: Paul Burton Signed-off-by: Masahiro Yamada List of files: /linux-6.15/arch/arc/plat-hsdk/Kconfig

ARCv2: [plat-hsdk]: Save accl reg pair by defaultThis manifsted as strace segfaulting on HSDK because gcc was targettingthe accumulator registers as GPRs, which kernek was not saving/restoringby default.Cc: stable@vger.kernel.org #4.14+Signed-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/plat-hsdk/Kconfig

a518d637 - ARC: [plat-hsdk] initial port for HSDK board

Tue, 15 Aug 2017 18:13:55 +0000

ARC: [plat-hsdk] initial port for HSDK boardThis initial port adds support of ARC HS Development Kit board with somebasic features such serial port, USB, SD/MMC and Ethernet.Essentially we run Linux kernel on all 4 cores (i.e. utilize SMP) andheavily use IO Coherency for speeding-up DMA-aware peripherals.Note as opposed to other ARC boards we link Linux kernel to0x9000_0000 intentionally because cores 1 and 3 configured with DCCMsituated at our more usual link base 0x8000_0000. We still can usememory region starting at 0x8000_0000 as we reallocate DCCM in ourplatform code.Note that PAE remapping for DMA clients does not work due to an RTL bug,so CREG_PAE register must be programmed to all zeroes, otherwise it willcause problems with DMA to/from peripherals even if PAE40 is not used.Acked-by: Rob Herring Signed-off-by: Alexey Brodkin Signed-off-by: Eugeniy Paltsev Signed-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/plat-hsdk/Kconfig
