Note: the existing code aliases the flash BAR into the MMIO bar. This is probably a bug. This patch does not correct the problem.

2011-05-05eepro100: Fix endianness issuesStefan Weil
Like other Intel devices, e100 (eepro100) uses little endian byte order. This patch was tested with these combinations: i386 host, i386 + mipsel guests (le-le) mipsel host, i386 guest (le-le) i386 host, mips + ppc guests (le-be) mips host, i386 guest (be-le) mips and mipsel hosts were emulated machines. v2: Use prefix for new functions. Add the same prefix to stl_le_phys. Fix alignment of mem (needed for word/dword reads/writes). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-05-05eepro100: Pad received short framesStefan Weil
QEMU sends frames smaller than 60 bytes to ethernet nics. Such frames are rejected by real NICs and their emulations. To avoid this behaviour, other NIC emulations pad received frames. This patch enables this workaround for eepro100, too. All related code is marked with CONFIG_PAD_RECEIVED_FRAMES, so we can drop this in case QEMU's networking code is ever changed.

2011-05-05eepro100: Remove unused structure elementStefan Weil
cppcheck reports that 'packet' is unused. It was only used to calculate the size of the preceding data. Removing it saves a lot of stack space (local variable rx). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2011-05-05eepro100: Avoid duplicate debug messagesStefan Weil
When DEBUG_EEPRO100 was enabled, unsupported writes were logged twice. Now logging in eepro100_write1 and eepro100_write2 is similar to the logging in eepro100_write4 (which already was correct). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2010-12-11Add endianness as io mem parameterAlexander Graf
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.

2010-10-07eepro100: Add support for multiple individual addresses (multiple IA)Stefan Weil
I reviewed the latest sources of Linux, FreeBSD and NetBSD. They all reset the multiple IA bit (multi_ia in BSD) to zero, but I did not find code which sets this bit to one (like it is done by some routers). Running Windows guests also did not set this bit. Intel's Open Source Software Developer Manual does not give much information on the semantics related to this bit, so I had to guess how it works. The guess was good enough to make the router emulation work. Related changes in this patch: * Update naming and documentation of the internal hash register. It is not limited to multicast, but also used for multiple IA. * Dump complete configuration register when debug traces are enabled. * Debug output when multiple IA bit is set during CmdConfigure. * Debug output when frames are received because multiple IA bit is set, or when they are ignored although it is set.

Commit 15e89f5916c9e82347cbd1fd416db3e348bab426 removed this setting, but it is still needed. Without this patch, e100 device drivers using interrupts don't work with qemu.

2010-04-06eepro100: Don't allow writing SCBStatusStefan Weil
SCBStatus is readonly, but most drivers which were derived from the old Linux eepro100.c do a word write to this address when they want to acknowledge interrupts. So we have to mask these writes here. The patch also removes old unused code for status read / write. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S.

2010-03-15eepro100: address pci todo's, use pci_set_xxMichael S. Tsirkin
