qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'

/**
|
|
|
|
* This serves as a bit of a tutorial on AHCI device programming:
|
|
|
|
*
|
|
|
|
* (1) Create a data buffer for the IDENTIFY response to be sent to
|
|
|
|
* (2) Create a Command Table buffer, where we will store the
|
|
|
|
* command and PRDT (Physical Region Descriptor Table)
|
2015-02-05 18:41:23 +01:00
|
|
|
* (3) Construct an FIS host-to-device command structure, and write it to
|
2015-02-05 18:41:27 +01:00
|
|
|
* the top of the Command Table buffer.
|
|
|
|
* (4) Create one or more Physical Region Descriptors (PRDs) that describe
|
|
|
|
* a location in memory where data may be stored/retrieved.
|
|
|
|
* (5) Write these PRDTs to the bottom (offset 0x80) of the Command Table.
|
|
|
|
* (6) Each AHCI port has up to 32 command slots. Each slot contains a
|
|
|
|
* header that points to a Command Table buffer. Pick an unused slot
|
|
|
|
* and update it to point to the Command Table we have built.
|
|
|
|
* (7) Now: Command #n points to our Command Table, and our Command Table
|
|
|
|
* contains the FIS (that describes our command) and the PRDTL, which
|
|
|
|
* describes our buffer.
|
|
|
|
* (8) We inform the HBA via PxCI (Command Issue) that the command in slot
|
|
|
|
* #n is ready for processing.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.

qtest/ahci: Store hba_base in AHCIQState
Store the HBA memory base address in the new state object, to simplify
function prototypes and encourage a more functional testing style.
This causes a lot of churn, but this patch is as "simplified" as I could
get it to be. This patch is therefore fairly mechanical and straightforward:
Any case where we pass "hba_base" has been consolidated into the AHCIQState
object and we pass the one unified parameter.
Any case where we reference "ahci" and "hba_state" have been modified to use
"ahci->dev" for the PCIDevice and "ahci->hba_state" to get at the base memory
address, accordingly.
Notes:
- A needless return is removed from start_ahci_device.
- For ease of reviewing, this patch can be reproduced (mostly) by:
# Replace (ahci, hba_base) prototypes with unified parameter
's/(QPCIDevice \*ahci, void \*\?\*hba_base/(AHCIQState *ahci/'
# Replace (ahci->dev, hba_base) calls with unified parameter
's/(ahci->dev, &\?hba_base)/(ahci)/'
# Replace calls to PCI config space using "ahci" with "ahci->dev"
's/qpci_config_\(read\|write\)\(.\)(ahci,/qpci_config_\1\2(ahci->dev,/'
After these, the remaining differences are easy to review by hand.
