2012-01-04vmstate, memory: decouple vmstate from memory APIAvi Kivity1-1/+3
Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-09-06block: Attach non-qdev devices as wellMarkus Armbruster1-0/+1
For now, this just protects against programming errors like having the same drive back multiple non-qdev devices, or untimely bdrv_delete(). Later commits will add other interesting uses. While there, rename BlockDriverState member peer to dev, bdrv_attach() to bdrv_attach_dev(), bdrv_detach() to bdrv_detach_dev(), and bdrv_get_attached() to bdrv_get_attached_dev().

2011-09-04pflash_cfi01/pflash_cfi02: convert to memory APIAvi Kivity1-45/+33
cfi02 is annoying in that is ignores some address bits; we probably want explicit support in the memory API for that. In order to get the correct opaque into the MemoryRegion object, the allocation scheme is changed so that the flash emulation code allocates memory, instead of the caller. This clears a FIXME in the flash code. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini1-1/+1
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2010-12-11Add endianness as io mem parameterAlexander Graf1-2/+4
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.

2010-01-27pflash: Buffer block writesEdgar E. Iglesias1-3/+9
Buffer block writes to avoid flushing every word access onto backing storage device. This significantly speeds up flash emulation for flashes connected through an 8 or 16-bit bus combined with backing storage (-pflash). Signed-off-by: Edgar E. Iglesias <edgar.iglesias@petalogix.com>
2010-01-24pflash: Dont open memarea for full IO if already done.Edgar E. Iglesias1-2/+4

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-27/+27
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-08-27Check block driver read error in pflash_cfi0xVijay Kumar1-1/+7
If a flash file of size smaller than the flash size is specified in the -pflash option, the block driver returns error. But the pflash_cfi0x ignores the error. This results in a flash content of all zeroes. And the simulation aborts while executing code. This patch adds the checks for errors from bdrv_read and escalates it to the calling code.

2008-10-11Increase write buffer size in pflash emulation (Thomas Petazzoni).balrog1-3/+3
The current flash emulation code advertises a write buffer size of 16 bytes (1 << 4, according to offset 0x2A of the CFI table). This is very small compared to normal write buffer sizes, and makes the process of writing to the flash very slow (at least from U-Boot). This patch increases this size to 2048 bytes. Except the modification of the CFI table, the only other required modification is to use "value" instead of "cmd" to set pfl->counter, because cmd is truncated to the 8 lower bits of value, while the number of bytes for a write can now be greater than 255 bytes.

2008-10-03Reset CFI01 flash wcycle after erase confirm (Thomas Petazzoni).balrog1-1/+1
pfl->wcycle was set to 1 when the erase confirm command was set, which lead to the next command being misinterpreted by Qemu: pflash_write: Unimplemented flash cmd sequence (offset 00000000, wcycle 0x1 cmd 0x20 value 0x70) This patch fixes this issue by resetting pfl->wcycle to 0 on erase confirm so that the next command is considered as a new one.

The IO index is now stored in its own field, instead of being wedged into the vaddr field. This eliminates the ROMD and watchpoint host pointer weirdness.
