2009-11-17Convert linux bootrom to external rom and fw_cfgAlexander Graf2-103/+31
We already have a working multiboot implementation that uses fw_cfg to get its kernel module etc. data in int19 runtime now. So what's missing is a working linux boot option rom. While at it I figured it would be a good idea to take the opcode generator out of pc.c and instead use a proper option rom, like we do with multiboot. So here it is - an fw_cfg using option rom for -kernel with linux! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-17Convert multiboot to fw_cfg backed data storageAlexander Graf2-14/+34
Right now we load the guest kernel to RAM, fire off the BIOS, hope it doesn't clobber memory and run an option rom that jumps into the kernel. That breaks with SeaBIOS, as that clears memory. So let's read all kernel, module etc. data using the fw_cfg interface when in the int19 handler. This patch implements said mechanism for multiboot.

We have several rom helpers currently, but none of them can get us code that spans several roms into a pointer. This patch introduces a function that copies over rom contents. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-17Block live migrationlirans@il.ibm.com1-2/+7
This patch introduces block migration called during live migration. Block are being copied to the destination in an async way. First the code will transfer the whole disk and then transfer all dirty blocks accumulted during the migration. Still need to improve transition from the iterative phase of migration to the end phase. For now transition will take place when all blocks transfered once, all the dirty blocks will be transfered during the end phase (guest is suspended). Changes from v4: - Global variabels moved to a global state structure allocated dynamically. - Minor coding style issues. - Poll block.c for tracking of dirty blocks instead of manage it here.

This function sends out the OPENED event to backends that have drive the chardevs. The 'reset' is now a historical artifact and we can now just call the function for what it is. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Uni-North AGP device mapping was accidentally dropped in 2e29bd04786003561303dcad940b38afe790fb9b. Map the device. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-11-15PPC64: Partial fix to Linux crash: revert to old devfnBlue Swirl1-1/+3
Before 2e29bd04786003561303dcad940b38afe790fb9b, Uni-North host and AGP bridge were using the same devfn, 11 << 3. The net effect was that only AGP bridge was visible. This was changed in the commit to 13 << 3 for AGP. Some of the later crashes happened due to NULL pointer dereferences generated by 07b7d05377a5e2b242ef0cce3d461d3284700fc0 and insufficient return value checks. Disable host device and revert AGP to 11 << 3. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-11-15PCI: make duplicate devfn allocation fatalBlue Swirl2-5/+3
Only two callers of pci_create_simple/pci_register_device bothered to check the return value. Other cases were prone to crashing with spurious NULL pointer dereferences. Make QEMU exit with an error message when devfn is attempted to be duplicated, also applies to case when the bus is full. Remove checks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

While writing working on an e1000 driver for my university's OS I noticed that some registers aren't readable in QEMU, but they should be readable as stated in Intels Driver Developer Manual (and also verified on real hardware). Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-12qdev: Check if unplug handler exists before calling itAmit Shah1-0/+2
A bus may have hotplugging enabled but not have the 'unplug' callback defined, which would lead to a crash on trying to unplug a device on the bus.

2009-11-12eepro100: Fix boot ROM supportStefan Weil1-0/+11
* Rename pxe-eepro100.bin to pxe-i82559er.bin. The other devices supported by eepro100.c need additional pxe boot ROM images. * Call rom_add_option during initialisation. The code won't work with two or more different eepro100 devices, because it only adds one option ROM, but this use case is perhaps never needed. Using this patch, model=i82559er at least works partially. For full support, more eepro100 patches are needed (will follow later, can be fetched from ar7 branch of QEMU).

2009-11-12serial: Add interface to set reference oscillator frequencyStefan Weil2-0/+8
Many (most?) serial interfaces have a programmable clock which provides the reference frequency ("baudbase"). So a fixed baudbase which is only set once can be wrong. omap1.c is an example which could use the new interface to change baudbase when the programmable clock changes. ar7 system emulation (still not part of standard QEMU) is similar to omap and already uses serial_set_frequency.

2009-11-09eepro100: Improve support for different devicesStefan Weil1-25/+143
* Add device properties (size of statistical data, extended tcb support) to EEPRO100State and set these values for the different devices. * Fix PCI configuration for existing devices. * Add initialisation code for missing devices. * Remove function device_supports_eTxCB. It is no longer needed. * Fix dump of statistical data. It now respects the real size of the statistical data. An endianess issue was fixed here, too. * CU_SHOWSTATS, CU_DUMPSTATS now write a completion value after the statistical data. There is no need to keep this value in eepro100_stats_t, so member "complete" could be removed. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-09pci: implement pci bridge filtering.Isaku Yamahata2-7/+151
This patch implements pci bridge filtering. TODO: currently almost all the map funcions assumes filtered_size == size and addr & ~(size - 1) == addr. However with bridge filtering, they aren't always true. Teach them such cases, such that filtered_size < size and addr & (size - 1) != 0.

2009-11-09pci: initialize pci config headers depending it pci header type.Isaku Yamahata3-5/+67
- Only sets default subsystem id for header type 00.(normal header type) because header type 01 doesn't have subsystem id, and uses the register for other purpose. So setting default subsystem id doesn't make sense. - initialize wmask more for header type 01.(bridge header type) Without those wmasks, linux was confused not boot, and lspci was confused not to print out expected IO/memory range.

add helper function to check ranges overlap suggested by Michael S. Tsirkin <mst@redhat.com>. His original suggestion was to use [first, last], however I chosen to use offset, length pair, i.e. [offset, offset + length) because pci configuration space related functions all uses offset and length pair, so it helps to avoid to type constant twice.

2009-11-09pci: make pci configuration transaction more accurate.Isaku Yamahata3-36/+108
This patch sorts out/enhances pci code to track pci bus topology more accurately. - Track host bus bridge with pci domain number. Although the current qemu implementation supports only pci domian 0 yet. - Track pci bridge parent-child relationship. When looking down from pci host bus for pci sub bus, be aware of secondary bus/subordinate bus. Thus pci configuration transaction is more accurately emulated. This patch adds new member to PCIBus to track pci bus topology. Since qdev already tracks down bus relationship, those new member wouldn't be necessary. However it would be addressed later because not all the pci device isn't converted to qdev yet.
