Dear Maintainers,
I have a Tyan TN71-BP012 power8 server, and its graphic is Aspeed AST2400. http://tyan.com/Barebones_TN71-BP012_BSP012T71V14HR-4T-3 Recently I test Ubuntu 15.10 ppc64el on it, the kernel ast driver works OK, but when test X, I found that the ast_drv.so build from the xf86-video-ast can not work, here is the error message from X: [ 7498.243] (II) LoadModule: "ast" [ 7498.244] (II) Loading /usr/lib/xorg/modules/drivers/ast_drv.so [ 7498.244] (EE) Failed to load /usr/lib/xorg/modules/drivers/ast_drv.so: /usr/lib/xorg/modules/drivers/ast_drv.so: undefined symbol: ioBase [ 7498.244] (II) UnloadModule: "ast" [ 7498.244] (II) Unloading ast [ 7498.244] (EE) Failed to load module "ast" (loader failed, 7) I searched the "ioBase", it is defined in the compiler.h under the MACRO "__powerpc__", so I just change the MACRO to let the driver can be load, then error again: [ 26963.956] (WW) Falling back to old probe method for ast [ 26963.956] (--) Assigning device section with no busID to primary device [ 26963.956] (--) Assigning device section with no busID to primary device [ 26963.956] (WW) AST: More than one matching Device section found: Autoconfigured Video Device ast [ 26963.956] (--) Chipset ASPEED Graphics Family found [ 26963.956] (EE) ast: The PCI device 0x2000 at 07@01:00:0 has a kernel module claiming it. [ 26963.956] (EE) ast: This driver cannot operate until it has been unloaded. So I just comment the "pci_device_has_kernel_driver" in ast_driver.c to let the probe continue, then error again: [ 22795.892] (II) AST(0): Creating default Display subsection in Screen section "Default Screen Section" for depth/fbbpp 24/32 [ 22795.892] (==) AST(0): Depth 24, (--) framebuffer bpp 32 [ 22795.892] (==) AST(0): Using gamma correction (1.0, 1.0, 1.0) [ 22795.892] (==) AST(0): RGB weight 888 [ 22795.892] (==) AST(0): Default visual is TrueColor [ 22795.892] (--) AST(0): Chipset: "ASPEED Graphics Family" [ 22795.892] (II) AST(0): Linear framebuffer at 0x82000000 [ 22795.893] (II) AST(0): IO registers at addr 0x81800000 [ 22795.893] (EE) AST(0): Map Memory Map IO Failed It seems that the xf86-video-ast driver is for a 32bit system? is there other X driver for the power8 machine using AST chips? BTW: The xf86-video-vesa can't work on the machine either, the error message is also "undefined symbol: ioBase". cheers Yu _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
