* Move QOM typedefs and add missing includesEduardo Habkost2020-09-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

* mac_dbdma: remove DBDMA_init() functionMark Cave-Ayland2017-09-271-1/+0Star
| | | | | | | | | Instead we can now instantiate the MAC_DBDMA object directly within the macio device. We also add the DBDMA device as a child property so that it is possible to retrieve later.

* mac_dbdma: remove unused IO fields from DBDMAStateMark Cave-Ayland2017-09-271-4/+0Star
| | | | | | | | | | | | | These fields were used to manually handle IO requests that weren't aligned to a sector boundary before this feature was supported by the block API. Once the block API changed to support byte-aligned IO requests, the macio controller was switched over to use it in commit be1e343 but these fields were accidentally left behind. Remove them, including the initialisation in DBDMA_init(). Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

| | | | | | | | | | | | | qemu-common.h should only be included by .c files. Its file comment explains why: "No header file should depend on qemu-common.h, as this would easily lead to circular header dependencies." qemu/iov.h includes qemu-common.h for QEMUIOVector stuff. Move all that to qemu/iov.h and drop the ill-advised include. Include qemu/iov.h where the QEMUIOVector stuff is now missing.

* macio: switch pmac_dma_write() over to new offset/len implementationMark Cave-Ayland2015-06-051-1/+2
| | | | | | | | | | | | | | | In particular, this fixes a bug whereby chains of overlapping head/tail chains would incorrectly write over each other's remainder cache. This is the access pattern used by OS X/Darwin and fixes an issue with a corrupt Darwin installation in my local tests. While we are here, rename the DBDMA_io struct property remainder to head_remainder for clarification.

* macio ide: Do remainder access asynchronouslyAlexander Graf2014-06-161-0/+5
| | | | | | | | | | | | | | | | | | The macio IDE controller has some pretty nasty magic in its implementation to allow for unaligned sector accesses. We used to handle these accesses synchronously inside the IO callback handler. However, the block infrastructure changed below our feet and now it's impossible to call a synchronous block read/write from the aio callback handler of a previous block access. Work around that limitation by making the unaligned handling bits also go through our asynchronous handler. This fixes booting Mac OS X for me.

* PPC: dbdma: Support unaligned DMA accessAlexander Graf2013-07-111-0/+3
| | | | | | | | | | | | | | | | | | | | The DBDMA engine really just reads bytes from a producing device (IDE in our case) and shoves these bytes into memory. It doesn't care whether any alignment takes place or not. Our code today however assumes that block accesses always happen on sector (512 byte) boundaries. This is a fair assumption for most cases. However, Mac OS X really likes to do unaligned, incomplete accesses that it finishes with the next DMA request. So we need to read / write the unaligned bits independent of the actual asynchronous request, because that one can only handle 512-byte-aligned data. We also need to cache these unaligned sectors until the next DMA request, at which point the data might be successfully flushed from the pipe. Signed-off-by: Alexander Graf <agraf@suse.de>
* PPC: dbdma: Move processing to ioAlexander Graf2013-07-111-1/+2
| | | | | | | | | | | | | Soon we will introduce intermediate processing pauses which will allow the bottom half to restart a DMA request that couldn't be fulfilled yet. For that to work, move the processing variable into the io struct which is what DMA providers work with. While touching it, also change it into a bool Signed-off-by: Alexander Graf <agraf@suse.de>
* PPC: dbdma: Move static bh variable to device structAlexander Graf2013-07-111-0/+1
| | | | | | | | | | | | The DBDMA controller has a bottom half to asynchronously process DMA request queues. This bh was stored as a gross static variable. Move it into the device struct instead. While at it, move all users of it to the new generic kick function. Signed-off-by: Alexander Graf <agraf@suse.de>
* PPC: dbdma: Introduce kick functionAlexander Graf2013-07-111-0/+1
| | | | | | | | | | The DBDMA engine really is running all the time, waiting for input. However we don't want to waste cycles constantly polling. So introduce a kick function that data providers can call to notify the DBDMA controller of new input. Signed-off-by: Alexander Graf <agraf@suse.de>
* PPC: dbdma: Move defines into header fileAlexander Graf2013-07-111-0/+118
| | | | | | | We usually keep struct and constant definitions in header files. Move them there to stay consistent and to make access to fields easier. Signed-off-by: Alexander Graf <agraf@suse.de>
* hw: move headers to include/Paolo Bonzini2013-04-081-0/+48
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
