Any pointers in this direction will be appreciated. For the moment, Xen 4.5 doesn't support device passthrough. We are working on 2 distinct solutions to allow non-pci device passthrough. Arianna has sent a patch series [1] to use "iomem" in the configuration file for xl. Her solution allows you to passthrough a range of MMIO to a specific guest. There is no device tree support (i.e xl won't create the node for your DT node in the device tree generate for the guest), and it won't work if the device is protected by an IOMMU. I'm actually working to add support for IRQ passthrough in a similar way. In a near future (once the latter item is done), I plan to add support for non-pci passthrough via the device tree. > Thanks & Regards Regards, [1] http://lists.xen.org/archives/html/xen-devel/2014-04/msg02646.html -- Julien Grall ^ permalink raw reply [flat|nested] 12+ messages in thread

People who are using 4.4 have been hardcoding mmio passthrough for specific platforms though, essentially by hacking the hypervisor code to do whatever magic was needed. The method is somewhat similar to the platform specific mappings callback which allows MMIO regions which are undescribed in the DT to be passed to dom0. xgene_storm_specific_mapping() is probably the best example. Essentially you just need to arrange for map_mmio_region() and gic_route_irq_to_guest() to be called for the appropriate regions when constructing the guest domain. Doing this statically for e.g. dom1 is pretty trivial, just hack some calls in somewhere on the domain create path with he appropriate checks. Allowing this to happen for any domain (useful if you want to reboot the guest domain) is a bit trickier, I'd probably be inclined to create a custom domctl and arrange for it to be called during domain build for the appropriate domain. Obviously this is all very hacky and as Julien says there are various things in the pipeline for 4.5 which will allow this to be done properly.

Hello Ian, Julien, Just to try out the passthrough using the hacks you mentioned, I made changes in xen to assign a GPIO controlled LED to domU by calling map_mmio_regions() in the domain creation path. After domU boots, when I try to access the LED using ioremap, ioread and iowrite from kernel space I see that I am not able to control the LED, also when I try to control LED using sysfs from user space it shows 'no such device' error. I am using xen 4.5 unstable and I have made the following changes in xen/common/domctl.c :: do_domctl(), after line 473: int passthrough = map_mmio_regions(d, 0x4805B000, 0x4805B000 + 0x1000, 0x4805B000); if (passthrough) printk("Failed to map passthrough_LED @ 0x4805B000 to dom%d\n", d->domain_id); While booting domU, in the logs I can see there is no error in map_mmio_regions(). Am I missing something here. Thanks and Regards Shubham Khandelwal ^ permalink raw reply [flat|nested] 12+ messages in thread

Am I missing something here. 0x4xxxxxxx is a RAM region on 4.5 (see the end of xen/include/public/arch-arm.h), I suspect your mmio mapping is being clobbered by a RAM mapping (and therefore that your answer above is "silently does nothing". Do you need this to be a 1:1 mapping or could you move it to some free space? Most of the low GB is free (but do check arch-arm.h) to be used for MMIO mappings.

You might also want to add debug to xen/arch/arm/traps.c inject_* to see if this is a trap which is going via Xen and being redirected to the guest or if it is generated directly by the MMU. If it is going via Xen then you could call dump_p2m_lookup on the guest IPA and see if it looks valid. > > 0x4xxxxxxx is a RAM region on 4.5 (see the end of > > xen/include/public/arch-arm.h), I suspect your mmio mapping is being > > clobbered by a RAM mapping (and therefore that your answer above is > > "silently does nothing". > > I just checked xen/include/public/arch-arm.h Line 372 is > > #define GUEST_RAM_BASE 0x80000000ULL > > So as per my understanding 0x4xxxxxxx is not a ram region and thus there should not be any clobbering.

IIRC, there should even be the possibility of setting up non 1:1 mappings, directly from the config file (uless that got dropped in the latest versions, which I could not follow closely). In any case, it look like both less work, and a more tested path (given the amount of attention and review the series is getting).
