2011-12-22sheepdog: move coroutine send/recv function to generic codePaolo Bonzini
Outside coroutines, avoid busy waiting on EAGAIN by temporarily making the socket blocking. The API of qemu_recvv/qemu_sendv is slightly different from do_readv/do_writev because they do not handle coroutines. It returns the number of bytes written before encountering an EAGAIN. The specificity of yielding on EAGAIN is entirely in qemu-coroutine.c. Reviewed-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2011-12-21hw/sd.c: Clear status bits when read via response r6Peter Maydell
Response format r6 includes a subset of the status bits; clear the clear-on-read bits which are read by an r6 response. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
2011-12-21hw/sd.c: Correct handling of APP_CMD status bitPeter Maydell
Fix some bugs in our implementation of the APP_CMD status bit: * the response to an ACMD should have APP_CMD set, not cleared * if an illegal ACMD is sent then the next command should be handled as a normal command This requires that we split "card is expecting an ACMD" from the state of the APP_CMD status bit (the latter indicates both "expecting ACMD" and "that was an ACMD").

2011-12-21hw/sd.c: Correct handling of type B SD status bitsPeter Maydell
Correct how we handle the type B ("cleared on valid command") status bits. In particular, the CURRENT_STATE bits in a response should be the state of the card when it received that command, not the state when it received the preceding command. (This is one of the issues noted in LP:597641.) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
2011-12-21hw/sd.c: Set ILLEGAL_COMMAND for ACMDs in invalid statePeter Maydell
App commands in an invalid state should set ILLEGAL_COMMAND, not merely return a zero response. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
2011-12-21hw/sd.c: Handle CRC and locked-card errors in normal code pathPeter Maydell
Handle returning CRC and locked-card errors in the same code path we use for other responses. This makes no difference in behaviour but means that these error responses will be printed by the debug logging code.

2011-12-21hw/sd.c: Handle illegal commands in sd_do_commandPeter Maydell
Add an extra sd_illegal value to the sd_rsp_type_t enum so that sd_app_command() and sd_normal_command() can tell sd_do_command() that the command was illegal. This is needed so we can do things like reset certain status bits only on receipt of a valid command. For the moment, just use it to pull out the setting of the ILLEGAL_COMMAND status bit into sd_do_command().

2011-12-21hw/sd.c: When setting ADDRESS_ERROR bit, don't clear everything elsePeter Maydell
Fix a typo that meant that ADDRESS_ERRORs setting or clearing write protection would clear every other bit in the status register. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>
2011-12-21hw/sd.c: On CRC error, set CRC error status bit rather than clearing itPeter Maydell
If we fail to validate the CRC for an SD command we should be setting COM_CRC_ERROR, not clearing it. (This bug actually has no effect currently because sd_req_crc_validate() always returns success.)

2011-12-21hw/sd.c: Fix the set of commands which are failed when card is lockedPeter Maydell
Fix bugs in the code determining whether to accept a command when the SD card is locked. Most notably, we had the condition completely reversed, so we would accept all the commands we should refuse and refuse all the commands we should accept. Correct this by refactoring the enormous if () clause into a separate function. We had also missed ACMD42 off the list of commands which are accepted in locked state: add it. This is one of the two problems reported in LP:597641. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Andrzej Zaborowski <andrew.zaborowski@intel.com>

since commit f9b29ca03 included in release 2.31 (docs below say 2.32 but that is not correct) and onwards g_thread_init is deprecated and calling it is not required: http://developer.gnome.org/glib/unstable/glib-Deprecated-Thread-APIs.html#g-thread-init g_thread_init has been deprecated since version 2.32 and should not be used in newly-written code. This function is no longer necessary. The GLib threading system is automatically initialized at the start of your program. Fixes bulid failure when warnings are treated as errors on fedora 17. I only tested the change to vl.c, and copy pasted to the two other locations (couldn't decide if a wrapper for calling g_thread_init is uglier).

2011-12-19qom: introduce get/set methods for PropertyPaolo Bonzini
This patch adds a visitor interface to Property. This way, QOM will be able to expose Properties that access a fixed field in a struct without exposing also the everything-is-a-string "feature" of qdev properties. Whenever the printed representation in both QOM and qdev (which is typically the case for device backends), parse/print code can be reused via get_generic/set_generic. Dually, whenever multiple PropertyInfos have the same representation in both the struct and the visitors the code can be reused (for example among all of int32/uint32/hex32).

2011-12-19qapi: protect against NULL QObject in qmp_input_get_objectPaolo Bonzini
A NULL qobj can occur when a parameter is fetched via qdict_get, but the parameter is not in the command. By returning NULL, the caller can choose whether to raise a missing parameter error, an invalid parameter type error, or use a default value. For example, qom-set could can use this to reset a property to its default value, though at this time it will fail with "Invalid parameter type". In any case, anything is better than crashing!
