Hello WINE Users: I am trying to build WINE on Snow Leopard with 64-bit support enabled (actually for my particular purpose I need to build a version of WINE with both 32-bit and 64-bit libraries supported). I am using the 1.1.29 source version.. I have been following the guide for building on Mac and 64-bit WINE at: http://wiki.winehq.org/MacOSX/Building http://wiki.winehq.org/Wine64 I get

Paravirt-ops guests which move the fixmap also end up moving the syscall = VDSO. This fails if it is prelinked at a fixed address, which is why = COMPAT_VDSO is broken under CONFIG_VMI (and also under CONFIG_XEN). = Several options are available to try to address this. Jan had cooked up = a patch for Xen that used build magic to find the parts of the VDSO that = need relocation. I

I'm implementing a more efficient version of the Xen iret paravirt_op, so that it can use the real iret instruction where possible. I really need to get access to per-cpu variables, so I can set the event mask state in the vcpu_info structure, but unfortunately at the point where INTERRUPT_RETURN is used in entry.S, the usermode %fs has already been restored. How would you feel if we changed

From: David Vrabel <david.vrabel@citrix.com> In 32 bit guests, if a userspace process has %eax == -ERESTARTSYS (-512) or -ERESTARTNOINTR (-513) when it is interrupted by an event /and/ the process has a pending signal then %eip (and %eax) are corrupted when returning to the main process after handling the signal. The application may then crash with SIGSEGV or a SIGILL or it may have subtly

The ALTERNATIVE() and ALTERNATIVE_2() macros are GNU assembler macros, which makes them quite inflexible for future changes. Convert them to preprocessor macros.

Xen Developers, I noticed that my PV ops guests cause the hypervisor to invoke hypercall_page_initialise twice from traps.c (i.e. through wrmsr_hypervisor_regs), for different hypercall_page addresses. Looking at the code, I see hvmloader.c causing one of those, in its main. I read the HVM Loader Xen wiki page, Googled, spelunked the source, etc. but cannot find where / why the other hypercall

I noticed a huge problem with the free space cache that was presenting as an early ENOSPC. Turns out when writing the free space cache out I forgot to take into account pinned extents and more importantly clusters. This would result in us leaking free space everytime we unmounted the filesystem and remounted it. I fix this by making sure to check and see if the current block group has a cluster

However just tweaking the define is not enough - we're not loading address of GOT into ebx before the call (on 32 bit ABIs) thus the call will be to nowhere. -- With best regards, Anton Korobeynikov Faculty of

Unfortunately we managed to not catch in our automatic testing this oversight during the porting of the corresponding pv-ops patch (info->irq now getting set later, which doesn''t matter for pv-ops as that has the event channel at hand).

Zsmalloc stores first free object's position into first_page->freelist in each zspage. If we change it with object index from first_page instead of location, we could squeeze it into page->mapping because the number of bit we need to store offset is at most 11bit.

Hello, Sorry if this has been addressed elsewhere, if so please let me know where! I'd like to compile 64-bit Wine 1.3.0 via GCC 4.5.1 (I use GCC 4.5.1 according to the instructions here: http://wiki.winehq.org/Wine64) on my Mac running Mac OS X 10.6.4 with a goal of taking advantage of the 8.0 GB of RAM I've got. I set CFLAGS="-march=native -m64", CXXFLAGS="-march=native
