| 01-Sep-2022 |
bouyer | Add PVH support for backend drivers grant operation. Now a domU in a PVH dom0 boots multiuser.

1.17 |
| 21-Feb-2021 |
jdolecek | in xen_shm_map(), make sure to unmap any successfully mapped pages before returning failure if there is partial failure
fix detection of partial failure - GNTTABOP_map_grant_ref can actually return zero for partial failure, so we need to always check all the entries to detect it
previously, DIAGNOSTIC kernel triggered panic() for partial failure, and non-DIAGNOSTIC kernel did not detect it at all, leading to Dom0 page fault later; since the mapping failure can be triggered by malicious DomU via bad grant reference, it's important to expect the calls to fail, and handle it gracefully without crashing Dom0

1.16 |
| 25-Apr-2020 |
bouyer | branches: 1.16.2; Merge the bouyer-xenpvh branch, bringing in Xen PV drivers support under HVM guests in GENERIC. Xen support can be disabled at runtime with boot -c disable hypervisor
|
1.15 |
| 19-Apr-2020 |
jdolecek | change interface for xen_shm_map() so that caller always supplies the VA, it now fails only if the Xen hypercall fails, in which case the failure is final
change xbdback to pre-allocate KVA on xbdback attach (and free on detach), so it has always KVA to map the request pages
remove no longer needed KVA allocation failure handling
|
1.14 |
| 13-Apr-2020 |
chs | slightly change and fix the semantics of pool_set*wat(), pool_sethardlimit() and pool_prime() (and their pool_cache_* counterparts):
- the pool_set*wat() APIs are supposed to specify thresholds for the count of free items in the pool before pool pages are automatically allocated or freed during pool_get() / pool_put(), whereas pool_sethardlimit() and pool_prime() are supposed to specify minimum and maximum numbers of total items in the pool (both free and allocated). these were somewhat conflated in the existing code, so separate them as they were intended.
- change pool_prime() to take an absolute number of items to preallocate rather than an increment over whatever was done before, and wait for any memory allocations to succeed. since pool_prime() can no longer fail after this, change its return value to void and adjust all callers.
- pool_setlowat() is documented as not immediately attempting to allocate any memory, but it was changed some time ago to immediately try to allocate up to the lowat level, so just fix the manpage to describe the current behaviour.
- add a pool_cache_prime() to complete the API set.

jdolecek | branches: 1.11.2; mark with XXXSMP all remaining spl*() and tsleep() calls
|
1.10 |
| 02-Sep-2011 |
dyoung | branches: 1.10.52; Report vmem(9) errors out-of-band so that we can use vmem(9) to manage ranges that include the least and the greatest vmem_addr_t. Update vmem(9) uses throughout the kernel. Slightly expand on the tests in subr_vmem.c, which still pass. I've been running a kernel with this patch without any trouble.

1.1.2.1 |
| 17-Oct-2007 |
bouyer | Prepare for xenamd64: - kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few #ifndef XEN) - move some files that can be shared between i386 and amd64 from xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code) - split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h - use <xen/...> instead of <machine/...> for cpu-independant include files.
more work needed here, i386-specific files should got out of arch/xen to arch/xeni386, and more code shared with arch/i386.
