2010-12-11isa_mmio: Always use little endianAlexander Graf1-5/+1
This patch converts the ISA MMIO bridge code to always use little endian mmio. All bswap code that existed was only there to convert from native cpu endianness to little endian ISA devices. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-12-11versatile_pci: Declare as little endianAlexander Graf1-13/+1
This patch replaces explicit bswaps with endianness hints to the mmio layer. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-12-11Add endianness as io mem parameterAlexander Graf1-1/+2
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2010-07-11pci: use PCI_DEVFN() where appropriate.Isaku Yamahata1-1/+1
Use PCI_DEVFN() and PCI_FUNC_MAX where appropriate. This patch make it clear that func = 0. test: The following object files with/without this patch are stripped and compared. They remains same. arm-softmmu/versatile_pci.o libhw32/ppce500_pci.o libhw32/unin_pci.o libhw64/ppce500_pci.o libhw64/unin_pci.o mips-softmmu/gt64xxx.o mips64-softmmu/gt64xxx.o mips64el-softmmu/gt64xxx.o mipsel-softmmu/gt64xxx.o Cc: Aurelien Jarno <aurelien@aurel32.net> Cc: Yu Liu <yu.liu@freescale.com> Cc: Paul Brook <paul@codesourcery.com> Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-02-14versatile_pci: cleanupMichael S. Tsirkin1-9/+2
Cleanup versatile_pci: no need to re-set fields to zero (pci core sets 0 already), use set_word for status field. Compile-tested only, but seems obvious. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-14versatile_pci: convert to symbolic namesMichael S. Tsirkin1-7/+10
This converts versatile_pci to use symbolic constants. Verified by comparing binary to original one. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-01pci: move pci_data_{read, write}() declaration from pci.h to pci_host.hIsaku Yamahata1-0/+1
Now pci host stuff has been moved from pci.[hc] to pci_host.[hc] so the declaration of pci_data_{read, write}() should be in pci_host.h This patch moves them from pci.h to pci_host.h for consistency.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-8/+8
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann1-4/+6
Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

2009-07-09qdev: update pci device registration.Gerd Hoffmann1-2/+7
Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch of parameters. Also adds config_read and config_write callbacks to PCIDeviceInfo, so drivers needing these can be converted to the qdev device API too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-06-16Remove io_index argument from cpu_register_io_memory()Avi Kivity1-1/+1
The parameter is always zero except when registering the three internal io regions (ROM, unassigned, notdirty). Remove the parameter to reduce the API's power, thus facilitating future change. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-05-23Add common BusStatePaul Brook1-2/+2
Implement and use a common device bus state. The main side-effect is that creating a bus and attaching it to a parent device are no longer separate operations. For legacy code we allow a NULL parent, but that should go away eventually. Also tweak creation code to veriry theat a device in on the right bus. Signed-off-by: Paul Brook <paul@codesourcery.com>

2009-03-13Add and use remaining #defines for PCI device IDs (Stuart Brady)aliguori1-1/+1
This patch adds and uses #defines for the remaining hardcoded PCI device IDs. It also moves definitions taken from linux/pci_ids.h into a separate header (hw/pci_ids.h), removes the 'RTL' from PCI_DEVICE_ID_REALTEK_RTL8029, and renames PCI_DEVICE_ID_FSL_E500 to PCI_DEVICE_ID_MPC8533E to match Linux's definition. Changes in v2: * Don't use C99-style comments * Move definitions from linux/pci_ids.h into a separate header * Rename PCI_DEVICE_ID_FSL_E500 to PCI_DEVICE_ID_MPC8533E Signed-off-by: Stuart Brady <stuart.brady@gmail.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6841 c046a42c-6fe2-441c-8c8c-71466251a162
2009-02-01Add and use #defines for PCI device classesblueswir11-2/+1
This patch adds and uses #defines for PCI device classes and subclases, using a new pci_config_set_class() function, similar to the recently added pci_config_set_vendor_id() and pci_config_set_device_id(). Change since v1: fixed compilation of hw/sun4u.c Signed-off-by: Stuart Brady <stuart.brady@gmail.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6491 c046a42c-6fe2-441c-8c8c-71466251a162
2009-01-26Define PCI vendor and device IDs in pci.h (Stuart Brady)aliguori1-4/+2
This patch defines PCI vendor and device IDs in pci.h (matching those from Linux's pci_ids.h), and uses those definitions where appropriate. Change from v1: Introduces pci_config_set_vendor_id() / pci_config_set_device_id() accessors as suggested by Anthony Liguori.
