Re: [edk2] [Patch 1/2] MdeModulePkg: Add PciSioSerialDxe driver
Mike,
Please check the updated PciSioSerialDxe driver and verify whether it can
replace the Quark version UART driver. Several changes were made:
1. Change the PCD structure layout
2. Change the SerialPortReadRegister function name to avoid linking error when
using DebugLibSerialPort
3. Support up to 921600 baud rate, and use the actual baud rate (same algorithm
as Quark version UART driver)
4. Flush Tx FIFO when reset or change the configuration of UART
Regards,
Ray

I recommend you change the names of these 2 functions.

Re: [edk2] [Patch 1/2] MdeModulePkg: Add PciSioSerialDxe driver
Hi Ray,
I agree a UINT64 Offset would be good for the Offset field. It would also be
good to order the fields and pad the structure so they are naturally aligned.
Maybe like the following with some comment changes:
typedef struct {
UINT16 VendorId; ///< Vendor ID to match the PCI device. The value
0x terminates the list of entries.
UINT16 DeviceId; ///< Device ID to match the PCI device
UINT32 ClockRate; ///< UART clock rate. Set to 0 for default clock
rate of 1843200 Hz
UINT64 Offset; ///< The byte offset into to the BAR
UINT8 BarIndex; ///< Which BAR to get the UART base address
UINT8 RegisterStride; ///< UART register stride in bytes. Set to 0 for
default register stride of 1 byte.
UINT8 Reserved[6];
} PCI_SERIAL_PARAMETER;
You need to add this module to the MdeModulePkg DSC file.
The code is currently limited to 115200 baud. There are many UARTs that
support higher baud rates, so this restriction needs to be removed.
If a non-standard ClockRate is used, then the actual baud rate may not exactly
match the expected baud rate, but as long as we are within a few percent, the
UART is stable.
I would like to use this driver as a replacement for the UART driver for Quark
that I have posted on GitHub at:
https://github.com/mdkinney/edk2/tree/Quark/QuarkSocPkg/QuarkSouthCluster/Uart/Dxe
It has support for baud rate up to 921600 and closest baud rate match with a
few percent and support for larger Tx FIFOs and extra flushes of the Tx FIFO
when doing a Reset or a UART config change. Please let me know if you want me
to help merge in some of those features to your patch.
Thanks,
Mike

PciSioSerialDxe driver can manages UARTs on a SIO chip or a PCI/PCIE
card.
It manages the SIO instance whose last device path node is a ACPI
device path and the HID in the ACPI device path node equals to
EISA_PNP_ID (0x501).
It also manages the PCI IO instance whose class code is 7/0/2 (16550
UART). But when proper value is set to PcdPciSerialParameters, the
driver can also manage non-standard PCI serial cards by matching
the Vendor ID and Device ID specified in PcdPciSerialParameters.
The PCI BAR index, IO/MMIO offset, register stride, clock rate can
also be specified through the same PCD.

Subject: [Patch 1/2] MdeModulePkg: Add PciSioSerialDxe driver
PciSioSerialDxe driver can manages UARTs on a SIO chip or a PCI/PCIE
card.
It manages the SIO instance whose last device path node is a ACPI
device path and the HID in the ACPI device path node equals to
EISA_PNP_ID (0x501).
It also manages the PCI IO instance whose class code is 7/0/2 (16550
UART). But when proper value is set to PcdPciSerialParameters, the
driver can also manage non-standard PCI serial cards by matching
the Vendor ID and Device ID specified in PcdPciSerialParameters.
The PCI BAR index, IO/MMIO offset, register stride, clock rate can
also be specified through the same PCD.
