2015-09-02ne2000: Drop ne2000_can_receiveFam Zheng
ne2000_receive already checks the same conditions and drops the packet if it's not ready, removing the .can_receive callback avoids the necessity to add explicit flushes when the conditions turn true (which is required by the new semantics of .can_receive since 6e99c63 "net/socket: Drop net_socket_can_send"). Plus the "return 1" if E8390_STOP is also suspicious. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2015-09-02vmxnet3: Drop net_vmxnet3_info.can_receiveFam Zheng
Commit 6e99c63 ("net/socket: Drop net_socket_can_send") changed the semantics around .can_receive for sockets to now require the device to flush queued pkts when transitioning to a .can_receive=true state.

2015-09-02rtl8139: Do not consume the packet during overflow in standard mode.Vladislav Yasevich
When operation in standard mode, we currently return the size of packet during buffer overflow. This consumes the overflow packet. Return 0 instead so we can re-process the overflow packet when we have room. This fixes issues with lost/dropped fragments of large messages.

2015-09-02rtl8139: Fix receive buffer overflow checkVladislav Yasevich
rtl8139_do_receive() tries to check for the overflow condition by making sure that packet_size + 8 does not exceed the available buffer space. The issue here is that RxBuffAddr, used to calculate available buffer space, is aligned to a a 4 byte boundry after every update. So it is possible that every packet ends up being slightly padded when written to the receive buffer. This padding is not taken into account when checking for overflow and we may end up missing the overflow condition can causing buffer overwrite. This patch takes alignment into consideration when checking for overflow condition.

The existing i440fx initialization code sets a PCI config register that isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is DRAMC (DRAM Control) and has nothing to do with the RAM size. This was implemented in commit ec5f92ce6ac8ec09056be77e03c941be188648fa because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to get the RAM size from QEMU, but I couldn't find out why coreboot did that. I assume it was a mistake, and the original code was supposed to be reading the DRB[0-7] registers (offsets 0x60-0x67). Document that coreboot-specific register offset in a macro and a comment, for future reference.

2015-08-13make: load only required dependency files.Victor Kaplansky
The old rules.mak loads dependency .d files using include directive with file glob pattern "*.d". This breaks the build when build tree has left-over *.d files from another build. This patch fixes this by - loading precise list of .d files made from *.o and *.mo. - specifying explicit list of required dependency info files for *.hex autogenerated sources. Note that Makefile still includes some .d in root directory by including "*.d". Signed-off-by: Victor Kaplansky <victork@redhat.com> Reviewed-by: Michael S.

2015-08-13make: fix where dependency *.d are stored.Victor Kaplansky
In rules like "bar/%.o: %.c" there is a difference between $(*D) and $(@D). $(*D) expands to '.', while $(@D) expands to 'bar'. It is cleaner to generate *.d in the same directory where appropriate *.o resides. This allows precise including of dependency info from .d files. As a hack, we also touch two sources for generated *.hex files. Without this hack, anyone doing "git pull; make" will not get *.hex rebuilt correctly since the dependency file would be missing.

2015-08-13i.MX: Fix UART driver to work with unitialized "chardev" deviceJean-Christophe Dubois
The "chardev" property initialization might have failed (for example because there are not enough chardevs provided by QEMU). The serial device emulator needs to be able to work with an uninitialized (NULL) chardev device pointer. This patch adds some missing tests on the chr pointer value before using it.
