* cadence_gem: Add debug msgs for rx desc movementPeter Crosthwaite2013-02-281-0/+2
| | | | | | | | | Add some helpful messages that show the rx descriptor pointer moving as packets are rxed.

* cadence_gem: Don't reset rx desc pointer on rx_enPeter Crosthwaite2013-02-281-4/+0
| | | | | | | | | | This doesn't happen in the real hardware. The Zynq TRM explicitly states that this bit has no effect on the rx descriptor pointer ("The receive queue pointer register is unaffected").

* cadence_gem: fix interrupt eventsPeter Crosthwaite2013-02-281-23/+4
| | | | | | | | | | Bits in the ISR were continually mirroring their corresponding TX/RX SR bits. This is incorrect. The ISR bits are only ever set at the time their corresponding event occurs.

* cadence_gem: factor out can_rx() logic replicationPeter Crosthwaite2013-02-281-1/+1
| | | | | | | | | The gem_receive() function replicates the logic for whether or not the device can rx. Just call the actual gem_can_receive() function in place.

* sysbus: Drop sysbus_from_qdev() cast macroAndreas Färber2013-01-211-1/+1

* Make all static TypeInfos constAndreas Färber2013-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

* net: reorganize headersPaolo Bonzini2012-12-191-1/+1
| | | | | | | | | Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* Rename target_phys_addr_t to hwaddrAvi Kivity2012-10-231-4/+4
| | | | | | | | | | | | | | | target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* net: Rename VLANClientState to NetClientStateStefan Hajnoczi2012-08-011-4/+4
| | | | | | | | | | | | | | | The vlan feature is no longer part of net core. Rename VLANClientState to NetClientState because net clients are not explicitly associated with a vlan at all, instead they have a peer net client to which they are connected. This patch is a mechanical search-and-replace except for a few whitespace fixups where changing VLANClientState to NetClientState misaligned whitespace.

* hw/cadence_gem: Make rx_desc_addr and tx_desc_addr uint32_tPeter Maydell2012-07-041-2/+2
| | | | | | | | | | | | Make the state fields rx_desc_addr and tx_desc_addr uint32_t; this matches the VMStateDescription, and also conforms to how hardware works: the registers don't magically become larger if the device is attached to a CPU with a larger physical address size. It also fixes a compile failure if the target_phys_addr_t type is changed to 64 bits. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Peter A. G.

* cadence_gem: avoid stack-writing buffer-overrunJim Meyering2012-06-191-1/+1
| | | | | | | | | | | | | Use sizeof(rxbuf)-size (not sizeof(rxbuf-size)) as the number of bytes to clear. The latter would always clear 4 or 8 bytes, possibly writing beyond the end of that stack buffer. Alternatively, depending on the value of the "size" parameter, it could fail to initialize the end of "rxbuf". Spotted by coverity.
