| | | | | | | | | | All callers of lsi_reselect have a lsi_request struct at hand anyway. So just pass it directly instead of having lsi_reselect search for it using the tag.

* lsi: have lsi_request for the whole life time of the request.Gerd Hoffmann2010-04-181-21/+32
| | | | | | | | | | | | | Right now lsi_request is allocated when a request is queued and released when a request is unqueued. With this patch applied the lsi_request is kept for the whole lifetime of the scsi request. Rationale: We can use it for per-request data then. The patch does that already for the request tag.

* sh_pci: fix memory and I/O accessAurelien Jarno2010-04-141-96/+15
| | | | | | | | | | | | | | | Since commit 8da3ff180974732fc4272cb4433fef85c1822961 ("MMIO callback interface changes"), the addresses passed to the I/O functions are an offset to the start of the area. As a consequence, there is no need to correct the address using the value of IOBR. This make possible the use of the default MMIO functions. Moreover the addresses are now remaped when the value if IOBR change. The memory area corresponds to the devices behing the PCI bus, it should not be mapped by the PCI controller. Remove the corresponding code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> (cherry-picked from commit 5ba9e9522cf572715ca1966b292f64fb78342e22)

* workaround for cmd646 bmdma register access while no dma is activeIgor V. Kovalenko2010-03-193-5/+4
| | | | | | | | | | | | | | | | | | | | | This is a workaround only, and is a partial revert of a few changes to BMDMAState which removed pci_dev field on the way. - cmd646 pci_from_bm() expects bm->unit value to correspond with bm data being passed to callback as opaque pointer. This breaks when write to dma control register of second channel happens when no dma operation is in progress, so bm->unit is zero for second channel, and pci_from_bm() returns garbage pointer. Crash happens shortly after that while dereferencing that pointer. v0->v1: cleaned up dead code from pci_from_bm. Signed-off-by: Igor V.

* segfault due to buffer overrun in usb-serialDavid S. Ahern2010-02-231-6/+22
| | | | | | | | | | | | | This fixes a segfault due to buffer overrun in the usb-serial device. The memcpy was incrementing the start location by recv_used yet, the computation of first_size (how much to write at the end of the buffer before wrapping to the front) was not accounting for it. This causes the next element after the receive buffer (recv_ptr) to get overwritten with random data.

| | | | | | | | | | | Win32 suffers from a very big memory leak when dealing with SCSI devices. Each read/write request allocates memory with qemu_memalign (ie VirtualAlloc) but frees it with qemu_free (ie free). Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks.

* roms: remove option rom packing logicGerd Hoffmann2009-12-192-61/+50
| | | | | | | | | | | | | Now that we load the option roms via fw_cfg, we can stop copying them to the 0xc000 -> 0xe000. The patch does just that. Also the rom loader gets simplified as all remaining users of the rom loader load the bits at a fixed address so the packing and aligning logic can go away.

* fw_cfg: add API for file transfer.Gerd Hoffmann2009-12-192-2/+62
| | | | | | | | | | | | | | | | This patch adds a file transfer interface to fw_cfg. Intended to be used for passing non-pci option roms and vgabios to seabios. Namespace is modeled after the existing cbfs filesystem support in seabios. Reading the new FW_CFG_FILE_DIR entry returns a file list. Fields there are in network byte order (aka bigendian). aliguori: fix fw_cfg.h for multiboot.bin, add proper fw_cfg.h declarations, quiet fprintf() in fw_cfg.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit abe147e0ce41c07e789f6627bcb01c905d1f9bbf)

* pci romfiles: add property, add default to PCIDeviceInfoGerd Hoffmann2009-12-196-32/+29
| | | | | | | | | | | This patch adds a romfile property to the pci bus. It allows to specify a romfile to load into the rom bar of the pci device. The default value comes from a new field in PCIDeviceInfo. The property allows to change the file and also to disable the rom loading using an empty string.

* Support PCI based option rom loadingAnthony Liguori2009-12-196-4/+44
| | | | | | | | | | | | | | | | | | Currently, we preload option roms into the option rom space in memory. This prevents DDIM from functioning correctly which severely limits the number of roms we can support. This patch introduces a pci_add_option_rom() which registers the PCI_ROM_ADDRESS bar which points to our option rom. It also converts over the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this new mechanism. The result is that PXE boot functions even with three unique types of cards.
