# SPDX-License-Identifier: GPL-2.0 config PPC_PS3 bool "Sony PS3" depends on PPC64 && PPC_BOOK3S && CPU_BIG_ENDIAN select PPC_CELL select USB_OHCI_LITTLE_ENDIAN select USB_OHCI_BIG_ENDIAN_MMIO select USB_EHCI_BIG_ENDIAN_MMIO select HAVE_PCI select IRQ_DOMAIN_NOMAP help This option enables support for the Sony PS3 game console and other platforms using the PS3 hypervisor. Enabling this option will allow building otheros.bld, a kernel image suitable for programming into flash memory, and vmlinux, a kernel image suitable for loading via kexec. menu "PS3 Platform Options" depends on PPC_PS3 config PS3_ADVANCED depends on PPC_PS3 bool "PS3 Advanced configuration options" help This gives you access to some advanced options for the PS3. The defaults should be fine for most users, but these options may make it possible to better control the kernel configuration if you know what you are doing. Note that the answer to this question won't directly affect the kernel: saying N will just cause the configurator to skip all the questions about these options. Most users should say N to this question. config PS3_HTAB_SIZE depends on PPC_PS3 int "PS3 Platform pagetable size" if PS3_ADVANCED range 18 20 default 20 help This option is only for experts who may have the desire to fine tune the pagetable size on their system. The value here is expressed as the log2 of the page table size. Valid values are 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively. If unsure, choose the default (20) with the confidence that your system will have optimal runtime performance. config PS3_DYNAMIC_DMA depends on PPC_PS3 bool "PS3 Platform dynamic DMA page table management" help This option will enable kernel support to take advantage of the per device dynamic DMA page table management provided by the Cell processor's IO Controller. This support incurs some runtime overhead and also slightly increases kernel memory usage. The current implementation should be considered experimental. This support is mainly for Linux kernel development. If unsure, say N. config PS3_VUART depends on PPC_PS3 tristate config PS3_PS3AV depends on PPC_PS3 tristate "PS3 AV settings driver" if PS3_ADVANCED select PS3_VUART default y help Include support for the PS3 AV Settings driver. This support is required for PS3 graphics and sound. In general, all users will say Y or M. config PS3_SYS_MANAGER depends on PPC_PS3 tristate "PS3 System Manager driver" if PS3_ADVANCED select PS3_VUART default y help Include support for the PS3 System Manager. This support is required for PS3 system control. In general, all users will say Y or M. config PS3_VERBOSE_RESULT bool "PS3 Verbose LV1 hypercall results" if PS3_ADVANCED depends on PPC_PS3 help Enables more verbose log mesages for LV1 hypercall results. If in doubt, say N here and reduce the size of the kernel by a small amount. config PS3_REPOSITORY_WRITE bool "PS3 Repository write support" if PS3_ADVANCED depends on PPC_PS3 help Enables support for writing to the PS3 System Repository. This support is intended for bootloaders that need to store data in the repository for later boot stages. If in doubt, say N here and reduce the size of the kernel by a small amount. config PS3_STORAGE depends on PPC_PS3 tristate config PS3_DISK tristate "PS3 Disk Storage Driver" depends on PPC_PS3 && BLOCK select PS3_STORAGE help Include support for the PS3 Disk Storage. This support is required to access the PS3 hard disk. In general, all users will say Y or M. config PS3_ROM tristate "PS3 BD/DVD/CD-ROM Storage Driver" depends on PPC_PS3 && SCSI select PS3_STORAGE help Include support for the PS3 ROM Storage. This support is required to access the PS3 BD/DVD/CD-ROM drive. In general, all users will say Y or M. Also make sure to say Y or M to "SCSI CDROM support" later. config PS3_FLASH tristate "PS3 FLASH ROM Storage Driver" depends on PPC_PS3 select PS3_STORAGE help Include support for the PS3 FLASH ROM Storage. This support is required to access the PS3 FLASH ROM, which contains the boot loader and some boot options. In general, PS3 OtherOS users will say Y or M. As this driver needs a fixed buffer of 256 KiB of memory, it can be disabled on the kernel command line using "ps3flash=off", to not allocate this fixed buffer. config PS3_VRAM tristate "PS3 Video RAM Storage Driver" depends on FB_PS3=y && BLOCK && m help This driver allows you to use excess PS3 video RAM as volatile storage or system swap. config PS3_LPM tristate "PS3 Logical Performance Monitor support" depends on PPC_PS3 help Include support for the PS3 Logical Performance Monitor. This support is required to use the logical performance monitor of the PS3's LV1 hypervisor. If you intend to use the advanced performance monitoring and profiling support of the Cell processor with programs like oprofile and perfmon2, then say Y or M, otherwise say N. config PS3GELIC_UDBG bool "PS3 udbg output via UDP broadcasts on Ethernet" depends on PPC_PS3 help Enables udbg early debugging output by sending broadcast UDP via the Ethernet port (UDP port number 18194). This driver uses a trivial implementation and is independent from the main PS3 gelic network driver. If in doubt, say N here. endmenu
