2014-06-23pc & q35: Add new machine opt max-ram-below-4gDon Slutz
This is a pc & q35 only machine opt. If you add enough PCI devices then all mmio for them will not fit below 4G which may not be the layout the user wanted. This allows you to increase the below 4G address space that PCI devices can use (aka decrease ram below 4G) and therefore in more cases not have any mmio that is above 4G. For example using "-machine pc,max-ram-below-4g=2G" on the command line will limit the amount of ram that is below 4G to 2G. Note: this machine option cannot be used to increase the amount of ram below 4G. Signed-off-by: Don Slutz <dslutz@verizon.com> Reviewed-by: Michael S.

2014-06-23q35: Use PC_Q35_COMPAT_1_4 on pc-q35-1.4 compat_propsEduardo Habkost
pc-q35-1.4 was incorrectly using PC_COMPAT_1_4 instead of PC_Q35_COMPAT_1_4. The only side-effect was that the hpet compat property (inherited from PC_Q35_COMPAT_1_7) was missing. Without this patch, pc-q35-1.4 inicorrectly initializes hpet-intcap to 0xff0104 (behavior introduced in QEMU 2.0, by commit 7a10ef51c2397ac4323bc786af02c58b413b5cd2).

2014-06-23qemu-char: avoid leaking unused fds in tcp_get_msgfds()Stefan Hajnoczi
Commit c76bf6bb8fbbb233a7d3641e09229d23747d5ee3 ("Add chardev API qemu_chr_fe_get_msgfds") extended the get_msgfds API from one to multiple file descriptors. It forgot to close unused file descriptors before freeing the file descriptor array. This patch prevents a file descriptor leak if the tcp_get_msgfds() callers requests fewer file descriptors than are available.

2014-06-23qemu-char: fix qemu_chr_fe_get_msgfd()Stefan Hajnoczi
Commit c76bf6bb8fbbb233a7d3641e09229d23747d5ee3 ("Add chardev API qemu_chr_fe_get_msgfds") broke qemu_chr_fe_get_msgfd() because it changed the return value. Callers expect -1 if no fd is available. The commit changed the return value to 0 (which is a valid file descriptor number) so callers always detected a file descriptor even if none was available.

2014-06-23e1000: improve auto-negotiation reporting via mii-toolGabriel L. Somlo
Using mii-tool (on F20-live), the following output is produced: SIOCGMIIREG on ens3 failed: Input/output error ens3: no autonegotiation, 1000baseT-FD flow-control, link ok The first line (SIOCGMIIREG error) is due to mii-tool's inability to read the PHY auto-negotiation expansion register. On the second line, "no autonegotiation" is wrong, and caused by the absence of a flag in the link partner ability register which would indicate that our link partner has acked us. This flag is listed as "reserved" in the Intel e1000 manual, but mii-tool uses it as LPA_LPACK from /usr/include/linux/mii.h. This patch adds read access to PHY_AUTONEG_EXP and defines the link partner ack flag, allowing mii-tool to generate output as normally expected: ens3: negotiated 1000baseT-FD flow-control, link ok Signed-off-by: Gabriel Somlo <somlo@cmu.edu> Reviewed-by: Alexander Graf <agraf@suse.de> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Michael S.

This patch emulates auto-negotiation when the network link status is modified externally (i.e. via "set_link <id> off/on"). Also, a couple of cleanup items: - unset PHY status reg. AUTONEG_COMPLETE during link_down() - set PHY status reg. AUTONEG_COMPLETE during autoneg_timer() only if we actually brought the link up. - group all checks for "can we, and should we autonegotiate?" together for more clarity.
