* ichsmb: fix block read operationAndriy Gapon2024-01-282-20/+46
| | | | | | | | | | | | | | | First of all and unlike I2C, it's not the master that dictates how many bytes to read in block read operation. It's the device that informs the master how many bytes it's sending back. Thus, for ichsmb_bread() the count parameter is purely an output parameter. The code has been changed to reflect that. The sanity checking of the response length is now done once it (the first byte of the response) is received. While here, handling of ICH_HST_STA_FAILED status bit has been added. Plus some code style improvements and some new code comments in the vicinity of the changed code.

* sys/dev/ichsmb: Silence unhandled SMBALERT device_printfsReid Linnemann2023-06-261-13/+2
| | | | | | | | | | | | | | | | | | | | | | | The ichsmb driver does not actually handle SMBALERT, other than by logging the first 16 occurences of the ICH_HST_STA_SMBALERT_STS_SMBALERT status flag. Because the SMBALERT is not acknowledged by the host, clearing it in the host status register does not appear to work as long as some slave device is pulling the SMBALERT line low, at least for C2000 chips. As a result, if a slave device does pull SMBALERT low the interrupt handler will always loop its maximum of 16 times attempting to clear all status register flags and device_printf the status register. The result is the kernel message buffer is littered with these device_printfs at every interrupt. To remedy the problem, the ICH_HST_STA_SMBALERT_STS flag is zeroed in the read host status register value, just as with ICH_HST_STA_INUSE_STS and ICH_HST_STA_HOST_BUSY. This allows the loop to break when no other flags that must be handled are set in the host status register. Additionally, because the SMBALERT is not actually handled the SMBALERT logging is omitted as it has no actual function at this time.

* Various updates to most of the smbus(4) drivers:John Baldwin2007-01-112-45/+35
| | | | | | | | | | | | | | | | | | | | | - Use printf() and device_printf() instead of log() in ichsmb(4). - Create the mutex sooner during ichsmb(4) attach. - Attach the interrupt handler later during ichsmb(4) attach to avoid races. - Don't try to set PCIM_CMD_PORTEN in ichsmb(4) attach as the PCI bus driver does this already. - Add locking to alpm(4), amdpm(4), amdsmb(4), intsmb(4), nfsmb(4), and viapm(4). - Axe ALPM_SMBIO_BASE_ADDR, it's not really safe to write arbitrary values into BARs, and the PCI bus layer will allocate resources now if needed. - Merge intpm(4) and intsmb(4) into just intsmb(4). Previously, intpm(4) attached to the PCI device and created an intsmb(4) child. Now, intsmb(4) just attaches to PCI directly. - Change several intsmb functions to take a softc instead of a device_t to make things simpler. Notes: svn path=/head/; revision=165951
* Minor overhaul of SMBus support:John Baldwin2006-09-111-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Change smbus_callback() to pass a void * rather than caddr_t. - Change smbus_bread() to pass a pointer to the count and have it be an in/out parameter. The input is the size of the buffer (same as before), but on return it will contain the actual amount of data read back from the bus. Note that this value may be larger than the input value. It is up to the caller to treat this as an error if desired. - Change the SMB_BREAD ioctl to write out the updated struct smbcmd which will contain the actual number of bytes read in the 'count' field. To preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD which doesn't copy the updated smbcmd back out to userland. I doubt anyone actually used the old BREAD anyway as it was rediculous to do a bulk-read but not tell the using program how much data was actually read. - Make the smbus driver and devclass public in the smbus module and push all the DRIVER_MODULE()'s for attaching the smbus driver to various foosmb drivers out into the foosmb modules. This makes all the foosmb logic centralized and allows new foosmb modules to be self-contained w/o having to hack smbus.c everytime a new smbus driver is added. - Add a new SMB_EINVAL error bit and use it in place of EINVAL to return an error for bad arguments (such as invalid counts for bread and bwrite). - Map SMB bus error bits to EIO in smbus_error(). - Make the smbus driver call bus_generic_probe() and require child drivers such as smb(4) to create device_t's via identify routines. Previously, smbus just created one anonymous device during attach, and if you had multiple drivers that could attach it was just random chance as to which driver got to probe for the sole device_t first. - Add a mutex to the smbus(4) softc and use it in place of dummy splhigh() to protect the 'owner' field and perform necessary synchronization for smbus_request_bus() and smbus_release_bus(). - Change the bread() and bwrite() methods of alpm(4), amdpm(4), and viapm(4) to only perform a single transaction and not try to use a loop of multiple transactions for a large request. The framing and commands to use for a large transaction depend on the upper-layer protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the smb(4) driver never allowed bulk read/writes of more than 32-bytes anyway. The other smb drivers only performed single transactions. - Fix buffer overflows in the bread() methods of ichsmb(4), alpm(4), amdpm(4), amdsmb(4), intpm(4), and nfsmb(4). - Use SMB_xxx errors in viapm(4). - Destroy ichsmb(4)'s mutex after bus_generic_detach() to avoid problems from child devices making smb upcalls that would use the mutex during their detach methods.
