similar to: PXE, Grub, MEMDISK, Bochs and a 10Meg image.

Is there a method to reboot a memdisk (floppy) image? I'm working on a DOS-based installation floppy that needs to repartition the hard disk prior to proceeding. DOS will only recognize the updated partition table after a reboot, but I'd like to be able to save information to the currently loaded memdisk floppy disk and simply reboot the image. Possible? I haven't had any luck with

I just discovered the wonderful world of ISOLINUX/MEMDISK while investigating how to make a boot CD that doesnt have floppy disk size limitations on its boot images. One thing has struck me as very odd about MEMDISK though - its support for hard disk images is restricted to physical disk images (ie. containing MBR/partition table). It doesnt support individual partition images, despite the fact

Hello ALL, I've got a diskless server working (under Gentoo), booting on it works. (a linux session start with no problem.) My Big problem, is to get Memdisk to boot with PXE. In fact memdisk is loaded, but it cannot find the img file. I've tried a lot of thing, but nothing works... tftp use : /diskless the config file for PXE in then in : /diskless/pxelinux.cfg/ the root for the

I have just pushed out SYSLINUX 3.10-pre21; this fixes ISOLINUX, and adds a fix for MEMDISK -- it so happens that running ISOLINUX under Bochs triggers a bug with similar behaviour as I've seen reported on here, so I'm *hoping* this might fix the "doesn't work without harddisk" problem and perhaps the IBM/USB problem some people have been reporting. Again, I really want

HPA, now that syslinux release madness has calmed down, could you provide some info on how we syslinux-minions/wannabes can use bochs and/or qemu to run (sys|pxe|iso|ext)linux in an emulated environment thats more conducive to debugging, single-stepping, and ultimately understanding how the magic happens ? tia jimc

The data structure |struct drm_vram_mm| and its helpers replace bochs' TTM-based memory manager. It's the same implementation; except for the type names. v4: * don't select DRM_TTM or DRM_VRAM_MM_HELPER v3: * use drm_gem_vram_mm_funcs * convert driver to drm_device-based instance v2: * implement bochs_mmap() with drm_vram_mm_mmap() Signed-off-by: Thomas Zimmermann <tzimmermann

Instead rely on the automatic clean, for which we just need to check that drm_mode_config_init succeeded. To avoid an inversion in the cleanup we also have to move the dev_private allocation over to drmm_kzalloc.

No need to store that, struct drm_framebuffer has all we need.

Not needed, writing to VBE_DISPI_INDEX_VIRT_HEIGHT has no effect anyway.

Call it from bochs_hw_setfb(). This also allows to make bochs_hw_setformat static.

It's always NULL, so just remove it.

The bochs driver (and virtual hardware) requires buffer objects to reside in video ram to display them to the screen. So it can not display the framebuffer console because the respective buffer object is permanently pinned in system memory. Using a shadow buffer for the console solves this problem. The console emulation will pin the buffer object only during updates from the shadow buffer.

Add bochs_hw_set_*_endian() helper functions, to set the framebuffer byteorder at mode set time. Support both DRM_FORMAT_XRGB8888 and DRM_FORMAT_BGRX8888 framebuffer formats, no matter what the native machine byte order is.
