2019-11-21lib/dma: remove DMA_MAP_FAST_IMPLSwapnil Ingle4-56/+20
muser works only with DMA_MAP_FAST_IMPL, So no need to support !DMA_MAP_FAST_IMPL implementation. Signed-off-by: Swapnil Ingle <swapnil.ingle@nutanix.com>

2019-11-08libmuser: Organise lm_ctx_create and friendsFelipe Franciosi4-94/+96
Current state of lm_ctx_create is quite messy. This cleans it up considerably, moving the pci config space creation to a separate helper. It gets rid of the 'extended' bool from dev_info, meaning that a client that wants to have a 4KiB config header should specify it on the corresponding region. This may all need reviewing later if we decide that other regions may be always handled by libmuser, in which case we can hide config, vga (and maybe rom?) entirely from our clients.

2019-11-06muser, libmuser: Do not abuse muser_cmd.mmap.response to return errSwapnil Ingle2-22/+10
muser_cmd.mmap.response is unsigned and should not be used to return errors, instead use muser_cmd.err Also fixed the code path to use valid errno values. Signed-off-by: Swapnil Ingle <swapnil.ingle@nutanix.com>

Cleanup
2019-11-04Hide ERR/REQ IRQs from clientsFelipe Franciosi2-9/+4
Users of libmuser do not need to know about ERR/REQ IRQs. We can later plumb the correct support to fire REQ IRQs (for graceful removal of devices) via a dedicated method (if ever needed). Similarly we should offer a method to raise an ERR IRQ accordingly. Signed-off-by: Felipe Franciosi <felipe@nutanix.com>
2019-11-04Remove incorrect guards on dump_buffer()Felipe Franciosi1-2/+0
The dump_buffer() method has internal guards, causing the function to be optimised out (within a compilation unit) if DEBUG is not set. The guards around the function export are not needed. Signed-off-by: Felipe Franciosi <felipe@nutanix.com>
2019-11-04Standardise function signaturesFelipe Franciosi10-150/+173
This makes all function signatures consistent, using a line break after the return type. It also review the usage of const across the project and fixes some other minor alignment issues. Signed-off-by: Felipe Franciosi <felipe@nutanix.com>

Previously we failed reads for capabilities that do not exist, that is any read in region 0x40 and 0x100. It is s perfectly legitimate to read that part of the PCI config space even if there's nothing there, we just return zeros. Signed-off-by: Thanos Makatos <thanos.makatos@nutanix.com>
