* ioemu: Fix bug in map cacheKeir Fraser2008-09-091-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | This small patch fixes an issue leading to a crash (segfault, although with earlier changesets I was seeing sigbus - not sure what changed) in qemu-dm when the following conditions occur: 1. A valid mapping for a bucket on a low address exists 2. Immediately after accessing memory mapped in this bucket, an access occurs to a high (beyond assigned ram) address beyond the 1GB limit for 32bit map cache wrapping around to the previous bucket's entry number. 3. The next call to map cache again accesses the low address. In this scenario, the guest mem for the low bucket has been unmapped by the remap_bucket caused by 2., but because the valid_mapping bit-test fails, map_cache returns before last_address_index has been updated. The subsequent call to map_cache therefore never remaps the low, valid bucket and instead returns a vaddr pointing to memory that has failed to get mapped.

* ioemu: various fixes to 18394:dade7f0bdc8dKeir Fraser2008-09-092-1/+10
| | | | | | | | | | | | | - fix ioemu segv with old firmware Without notifying ioemu of address, ioemu will segv. - fix qemu-dm segv with malicous firmware If notifying ioemu more than once, ioemu will segv. Usually such cases don't happen, but malicious guest can do it intentionally. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
* ioemu: fix offset of MSI-X memory-mapped table.Keir Fraser2008-09-051-1/+1
| | | | | | | | | Current code does not set dev->msix->table_off variable. The offset of MSI-X memory mapped table is treated as 0. The wrong region is unmapped from guest physical memory space. As a result, guest device driver can't access memory mapped resource. Signed-off-by: Yuji Shimada <shimada-yxb@necst.nec.co.jp>

| | | | | | | | For HVM guest, we can't do pci-attach/pci-detach for >64 times due to the meaningless checking in pci_register_device(). I made a test of 300 times of attach/detach and everything now works well. Signed-off-by: Dexuan Cui <dexuan.cui@intel.com>

* hvm: Use main memory for video memory.Keir Fraser2008-08-276-198/+223
| | | | | | | | | | | | | | | | | | | | | | | | | | When creating an HVM domain, if e.g. another domain is created before qemu allocates video memory, the extra 8MB memory ballooning is not available any more, because it got consumed by the other domain. This fixes it by taking video memory from the main memory: - make hvmloader use e820_malloc to reserve some of the main memory and notify ioemu of its address through the Xen platform PCI card. - add XENMAPSPACE_mfn to the xen_add_to_physmap memory op, to allow ioemu to move the MFNs between the original position and the PCI mapping, when LFB acceleration is disabled/enabled - add a remove_from_physmap memory op, to allow ioemu to unmap it completely for the case of old guests with acceleration disabled. - add xc_domain_memory_translate_gpfn_list to libxc to allow ioemu to get the MFNs of the video memory. - have xend save the PCI memory space instead of ioemu: if a memory page is there, the guest can access it like usual memory, so xend can safely be responsible to save it. The extra benefit is that live migration will apply the logdirty optimization there too. - handle old saved images, populating the video memory from ioemu if really needed.

* ioemu, passthrough: fix flag for expansion rom base address register.Keir Fraser2008-08-011-0/+7
| | | | | | | | | | | | | | | pt_bar_reg_parse() is called for expansion rom base address register. Currently it returns PT_BAR_FLAG_MEM if bit 0 is 0. It returns PT_BAR_FLAG_IO if bit 0 is 1. But bit 0 in expansion rom base address register is enable bit. If bit 0 is 1 for some reason, it returns PT_BAR_FLAG_IO. Expansion rom is mapped to memory space. It should return PT_BAR_FLAG_MEM. After applying this patch, it returns PT_BAR_FLAG_MEM regardless of bit 0, when it is called for expansion rom base address register. Signed-off-by: Yuji Shimada <shimada-yxb@necst.nec.co.jp>

* ioemu: fix libpci error handling.Keir Fraser2008-08-011-6/+4
| | | | | | | | | | | libpci returns ALL F when error occurs. Currently, if libpci returns ALL F, emulation stops. But it is possible that the field of real register which is read by guest software is ALL F.

| | | | | | | | | | | | | | | | This patch fixes writing handlers for base address registers (include expansion rom base address register) as follows. It can be applied to both ioemu-remote and ioemu. - Current implementation can not work fine when base address registers are accessed via 1 byte write access and 2 byte write access. This patch enables them. - Currently guest software can set address which is not aligned with resource size and page size. The patch does not allow guest software to set unaligned address.

I implemented following Capability Structures and Device Specific Registers. * Configuration Header Type 0 -> emulation. "emulation" does not mean no accessing real I/O device. Access real I/O device, but guest value and real value might be different. * MSI Capability Structure -> emulation. Behavior is not changed from existed implementation in pt-msi.c, although code is changed. * MSI-X Capability Structure -> emulation. Behavior is not changed from existed implementation in pt-msi.c, although code is changed. * PCI Express Capability Structure -> emulation. * PCI Power Management Capability Structure -> emulation. * Vital Product Data Capability Structure -> emulation. Emulated register is only Next Capability Pointer Register. All other registers are passthrough. * Vendor Specific Capability Structure -> emulation Emulated register is only Next Capability Pointer Register. All other registers are passthrough. * Device Specific Register (exclude capability structures) -> passthrough. The device drivers in guest domain are allowed to access Device Specific Register. So various I/O device will work. I assigned following device to guest domain, and they worked fine. - PCIe NIC (MSI) - PCI NIC (MSI) - UHCI (INTx interrupt) - IDE Controller (INTx interrupt) Signed-off-by: Yuji Shimada <shimada-yxb@necst.nec.co.jp>
