This patch provides the name of the architecture in the target.xml if available. This allows the remote gdb to detect the target architecture on its own - so there is no need to specify it manually (e.g. if gdb is started without a binary) using "set arch *arch_name*". The name of the architecture is provided by a callback that can be implemented by all architectures. The arm implementation has special handling for iwmmxt and returns arm otherwise.

2016-01-26xen: make it possible to build without the Xen PV domain builderIan Campbell4-5/+31
Until the previous patch this relied on xc_fd(), which was only implemented for Xen 4.0 and earlier. Given this wasn't working since Xen 4.0 I have marked this as disabled by default. Removing this support drops the use of a bunch of symbols from libxenctrl, specifically: - xc_domain_create - xc_domain_destroy - xc_domain_getinfo - xc_domain_max_vcpus - xc_domain_setmaxmem - xc_domain_unpause - xc_evtchn_alloc_unbound - xc_linux_build This is another step towards only using Xen libraries which provide a stable inteface.

2016-01-26xen: Use stable library interfaces when they are available.Ian Campbell2-2/+88
In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. Specifically libxenevtchn, libxengnttab and libxenforeignmemory. Previous patches have already laid the groundwork for using these by switching the existing compatibility shims to reflect the intefaces to these libraries. So all which remains is to update configure to detect the libraries and enable their use. Although they are notionally independent we take an all or nothing approach to the three libraries since they were added at the same time. The only non-obvious bit is that we now open a proper xenforeignmemory handle for xen_fmem instead of reusing the xen_xc handle. Build tested with 4.0 .. 4.6 (inclusive) and the patches targetting 4.7 which adds these libraries. This uses CONFIG_XEN_CTRL_INTERFACE_VERSION == 471 to cover the introduction of these new interfaces.

2016-01-26xen: Switch uses of xc_map_foreign_{pages,bulk} to use libxenforeignmemory API.Ian Campbell8-22/+56
In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxenforeignmemory which provides access to privileged foreign mappings and which will provide an interface equivalent to xc_map_foreign_{pages,bulk}. The new xenforeignmemory_map() function behaves like xc_map_foreign_pages() when the err argument is NULL and like xc_map_foreign_bulk() when err is non-NULL, which maps into the shim here onto checking err == NULL and calling the appropriate old function. Note that xenforeignmemory_map() takes the number of pages before the arrays themselves, in order to support potentially future use of variable-length-arrays in the prototype (in the future, when Xen's baseline toolchain requirements are new enough to ensure VLAs are supported). In preparation for adding support for libxenforeignmemory add support to the <=4.0 and <=4.6 compat code in xen_common.h to allow us to switch to using the new API. These shims will disappear for versions of Xen which include libxenforeignmemory. Since libxenforeignmemory will have its own handle type but for <= 4.6 the functionality is provided by using a libxenctrl handle we introduce a new global xen_fmem alongside the existing xen_xc. In fact we make xen_fmem a pointer to the existing xen_xc, which then works correctly with both <=4.0 (xc handle is an int) and <=4.6 (xc handle is a pointer). In the latter case xen_fmem is actually a double indirect pointer, but it all falls out in the wash. Unlike libxenctrl libxenforeignmemory has an explicit unmap function, rather than just specifying that munmap should be used, so the unmap paths are updated to use xenforeignmemory_unmap, which is a shim for munmap on these versions of xen. The mappings in xen-hvm.c do not appear to be unmapped (which makes sense for a qemu-dm process) In fb_disconnect this results in a change from simply mmap over the existing mapping (with an implicit munmap) to expliclty unmapping with xenforeignmemory_unmap and then mapping the required anonymous memory in the same hole. I don't think this is a problem since any other thread which was racily touching this region would already be running the risk of hitting the mapping halfway through the call. If this is thought to be a problem then we could consider adding an extra API to the libxenforeignmemory interface to replace a foreign mapping with anonymous shared memory, but I'd prefer not to.

2016-01-26xen: Switch uses of xc_map_foreign_range into xc_map_foreign_pagesIan Campbell3-18/+19
In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxenforeignmemory which provides access to privileged foreign mappings and which will provide an interface equivalent to xc_map_foreign_{pages,bulk}. In preparation for this switch all uses of xc_map_foreign_range to xc_map_foreign_pages. This is trivial because size was always XC_PAGE_SIZE so the necessary adjustments are trivial: * Pass &mfn (an array of length 1) instead of mfn. The function takes a pointer to const, so there is no possibily of mfn changing due to this change. * Pass nr_pages=1 instead of size=XC_PAGE_SIZE There is one wrinkle in xen_console.c:con_initialise() where con->ring_ref is an int but can in some code paths (when !xendev->dev) be treated as an mfn. I think this is an existing latent truncation hazard on platforms where xen_pfn_t is 64-bit and int is 32-bit (e.g. amd64, both arm* variants). I'm unsure under what circumstances xendev->dev can be NULL or if anything elsewhere ensures the value fits into an int. For now I just use a temporary xen_pfn_t to in effect upcast the pointer from int* to xen_pfn_t*. In xenfb.c:common_bind we now explicitly launder the mfn into a xen_pfn_t, so it has the correct type to be passed to xc_map_foreign_pages and doesn't provoke warnings on 32-bit x86.

In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxengnttab which provides access to grant tables. In preparation for this switch the compatibility layer in xen_common.h (which support building with older versions of Xen) to use what will be the new library API. This means that the gnttab shim will disappear for versions of Xen which include libxengnttab. To simplify things for the <= 4.0.0 support we wrap the int fd in a malloc(sizeof int) such that the handle is always a pointer. This leads to less typedef headaches and the need for XC_HANDLER_INITIAL_VALUE etc for these interfaces.

2016-01-26xen_console: correctly cleanup primary console on teardown.Ian Campbell1-5/+2
All of the work in con_disconnect applies to the primary console case (when xendev->dev is NULL). Therefore remove the early check and bail and allow it to fall through. All of the existing code is correctly conditional already. The ->dev and ->gnttabdev handles are either both set or neither. For consistency with con_initialise() with to the former here too. With this con_initialise and con_disconnect now mirror each other. Fix up a hard tab in the function while editing.

2016-01-26scripts/dump-guest-memory.py: Fix module docstringJanosch Frank1-17/+18
The module docstring is changed into a multi-line comment to comply with pep 257. The comment about the docstring that gets used by gdb to print the help is moved to the location of the docstring.

By modelling the ELF with ctypes we not only gain full python 3 support but can also create dumps for different architectures more easily.

2016-01-26scripts/dump-guest-memory.py: Improve python 3 compatibilityJanosch Frank1-11/+15
This commit does not make the script python 3 compatible, it is a preparation that fixes the easy and common incompatibilities. Print is a function in python 3 and therefore needs braces around its arguments. Range does not cast a gdb.Value object to int in python 3, we have to do it ourselves.
