And it sure does, there's no known software workaround. - Don't allow passing PSL_FP from MSR userland bits (userland can cause panic). - Fix ghost interrupt deliveries where asserted line re-entered the exception. - Ensure interrupt level-mask flag is set by default. - Tag mmaped DMA address as cacheable unless memory was explicitly allocated as uncached (only for 440, OEA probably could use it too). - Fix up 440 TLB decoding in ddb. - Fix pmap handling of reserved windows that may be mapped from userland. - Refactor L2 cache handling, make it more maintainable and in style of other ports. - Decode PLL straps and let the user know at what base frequency does the board run (useful if the user wants to apply firmware update, because images are built for different base freqs). - Minor trap stuff: decode and clear MCSR in a single helper, dump TLB on parity checks, user-mode MCHK are now SIGBUS. - Try to sanely handle the fact that 460EX has SERDES PHY that can either serve PCIe port or SATA - detect that and attach drivers accordingly. @ text @# $NetBSD: SAM460EX,v 1.6 2026/06/23 22:07:46 rkujawa Exp $ # # SAM460EX -- ACube Sam460ex (AMCC 460EX) # include "arch/evbppc/conf/std.sam460ex" #ident "SAM460EX-$Revision: 1.6 $" maxusers 32 options SAM460EX_FDT # parse U-Boot supplied device tree options PPC4XX_L2CACHE # on-chip 256KB L2 # # Diagnostic/debugging support options # #options DIAGNOSTIC # cheap kernel consistency checks #options DEBUG # expensive debugging checks/support options DDB # in-kernel debugger options DDB_HISTORY_SIZE=512 # enable history editing in DDB options TRAP_PANICWAIT makeoptions COPY_SYMTAB=1 # size for embedded symbol table options KTRACE # system call tracing makeoptions DEBUG="-g" # compile full symbol table # # File systems # file-system FFS # UFS file-system EXT2FS # Linux ext2fs file-system MSDOSFS # FAT file-system KERNFS # /kern file-system PTYFS # /dev/pts/N support file-system TMPFS # Efficient memory file-system options FFS_EI # Enable Endian Independent options DKWEDGE_AUTODISCOVER # Automatically add dk(4) instances options DKWEDGE_METHOD_MBR # Support MBR partitions as wedges options DKWEDGE_METHOD_RDB # Support RDB partitions as wedges file-system NFS # Network File System client options NFS_BOOT_DHCP # Support DHCP NFS root # # Networking options # options INET options INET6 # # Kernel root file system and dump configuration. # config netbsd root on ? type ? # # Device configuration # plb0 at root # Processor Local Bus cpu0 at plb? # CPU # On-chip Peripheral Bus support opb* at plb? # On-chip Peripheral Bus com* at opb? addr ? irq ? # UARTs wdog* at opb? # On-chip Watchdog ebc0 at plb? # External Bus Controller samfpga0 at ebc0 bank 2 # Lattice XP2 FPGA gpio0 at samfpga0 # GPIOs on J22 connector opbgpio* at opb? addr ? irq ? # On-chip GPIO gpio1 at opbgpio0 # GPIO0-31 gpio2 at opbgpio1 # GPIO32-63 gpiic* at opb? addr ? irq ? # On-chip IIC iic* at gpiic? # I2C bus strtc0 at iic0 addr 0x68 flags 62 # M41T62 RTC (M41T80 under QEMU) spdmem0 at iic0 addr 0x50 # DDR2 SPD EEPROM #seeprom0 at iic0 addr 0x54 flags 8 # U-Boot env EEPROM # only EMAC0 is wired on the Sam460ex emac0 at opb0 addr 0xef600e00 irq 80 # Ethernet Media Access Controller options EMAC_EVENT_COUNTERS options EMAC_RGMII_PHY # both EMACs use the RGMII0 bridge options EMAC_TAH # MII/PHY support makphy* at mii? phy ? # Marvell 88E1121R (dual GbE PHY) ukphy* at mii? phy ? # generic/unknown PHYs # PCI bus support options PCI_NETBSD_CONFIGURE pcix0 at plb? # 460EX PLB-PCIX host bridge pciex0 at plb? # 460EX PCIe root complex 0 pciex1 at plb? # 460EX PCIe root complex 1 pci* at pcix? pci* at pciex? ppb* at pci? dev ? function ? # PCI-PCI bridges pci* at ppb? bus ? # on-board SM502 framebuffer, selected via console=sm502 voyager0 at pci? dev ? function ? # SM502 multimedia processor voyagerfb0 at voyager0 # SM502 framebuffer console options VOYAGERFB_MODE_SETTING # DDC/EDID readout + mode-setting vac0 at voyager0 # SM502 AC97-link (Realtek ALC655) # audio audio* at audiobus? spkr* at audio? # tone interface, synthesized via audio wsbell* at spkr? # bell for the wscons display # selected via console=pci radeonfb* at pci? dev ? function ? # ATI Radeon R100 - R3XX pm2fb* at pci? dev ? function ? # 3Dlabs Permedia 2/2v framebuffer wsdisplay* at wsemuldisplaydev? options WSEMUL_VT100 options WSDISPLAY_SCROLLSUPPORT options FONT_BOLD8x16 # bitmap font satalink* at pci? dev ? function ? # SATALink siisata* at pci? dev ? function ? # SATA shares SERDES PHY with one of PCI root complexes, but we detect # which one was enabled on the firmware level and configure accordingly. dwcsata0 at plb? addr 0xbffd1000 irq 96 # on-chip DWC SATA-II options DWCSATA_PIO_ONLY # force PIO mode atabus* at ata? wd* at atabus? drive ? flags 0x0000 # On-chip USB controllers. # # Due to 460ex CHIP_16 errata, we can not safely operate both EHCI and OHCI # at the same time.
