* pci-arbiter: Probe devices and map regionsJoan Lledó2020-09-131-4/+20
| | | | | | | | | | | This adapts the arbiter to a bug fixed in libpciaccess. We were relying on the library to probe devices and map regions but it's the arbiter who should do it. * pci-arbiter/pcifs.c: * create_fs_tree(): probe the device to find regions and rom * pci-arbiter/func_files.c: * io_region_file(): map region on the first access attempt
* pci-arbiter: Use libpciaccess instead of embedding itDamien Zammit2019-11-031-19/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes all embedded pciaccess code from the arbiter and instead uses the external pciaccess library. * pci-arbiter/Makefile: * Remove pci_access.c and x86_pci.c from the sources. * pci-arbiter/func_files.c: * io_config_file: Use a harcoded PCI config size. * read_rom_file: Grab the full rom first, then return the requested amount. * pci-arbiter/main.c: * main: Call create_fs_tree() w/o pci_sys. Since it's not part of the translator anymore. * pci-arbiter/netfs_impl.c: * netfs_attempt_read: Send pci_device_cfg_read() as the read op. * netfs_attempt_write: Send pci_device_cfg_write() as the write op. * pci-arbiter/pci-ops.c: * S_pci_conf_read: Call libpciaccess' pci_device_cfg_read(). * S_pci_conf_write: Call libpciaccess' pci_device_cfg_write(). * S_pci_get_dev_rom: Set rom.base_addr to zero for the moment, until libpciaccess esposes it properly. * pci-arbiter/pci_access.c: Deleted * pci-arbiter/pci_access.h: Deleted * pci-arbiter/pcifs.c: * create_fs_tree: Remove the pci_sys parameter. Use libpciaccess' iterator. Use a hardcoded config space size. * pci-arbiter/pcifs.h: Definitions for changes in pcifs.c. * pci-arbiter/x86_pci.c: Deleted. * pci-arbiter/x86_pci.h: Deleted.
