2020-03-21ice: create function to read a section of the NVM and Shadow RAMJacob Keller3-7/+85
The NVM contents are read via firmware by using the ice_aq_read_nvm function. This function has a couple of limits: 1) The AdminQ commands can only take buffers sized up to 4Kb. Thus, any larger read must be split into multiple reads. 2) when reading from the Shadow RAM, reads must not cross sector boundaries. The sectors are also 4Kb in size. Implement the ice_read_flat_nvm function to read portions of the NVM by flat offset. That is, to read using offsets from the start of the NVM rather than from a specific module. This function will be able to read both from the NVM and from the Shadow RAM. For simplicity NVM reads will always be broken up to not cross 4Kb page boundaries, even though this is not required unless reading from the Shadow RAM. Use this new function as the implementation of ice_read_sr_word_aq. The ice_read_sr_buf_aq function is not modified here. This is because a following change will remove the only caller of that function in favor of directly using ice_read_flat_nvm. Thus, there is little benefit to changing it now only to remove it momentarily. At the same time, the ice_read_sr_aq function will also be removed.

2020-03-20ice: use __le16 types for explicitly Little Endian valuesJacob Keller1-5/+7
The ice_read_sr_aq function returns words in the Little Endian format. Remove the need for __force and typecasting by using a local variable in the ice_read_sr_word_aq function. Additionally clarify explicitly that the ice_read_sr_aq function takes storage for __le16 values instead of using u16. Being explicit about the endianness of this data helps when using tools like sparse to catch endian-related issues.

2020-03-10ice: Fix removing driver while bare-metal VFs pass trafficBrett Creeley3-10/+29
Currently, if there are bare-metal VFs passing traffic and the ice driver is removed, there is a possibility of VFs triggering a Tx timeout right before iavf_remove(). This is causing iavf_close() to not be called because there is a check in the beginning of iavf_remove() that bails out early if (adapter->state < IAVF_DOWN_PENDING). This makes it so some resources do not get cleaned up. Specifically, free_irq() is never called for data interrupts, which results in the following line of code to trigger: pci_disable_msix() free_msi_irqs() ... BUG_ON(irq_has_action(entry->irq + i)); ... To prevent the Tx timeout from occurring on the VF during driver unload for ice and the iavf there are a few changes that are needed. [1] Don't disable all active VF Tx/Rx queues prior to calling pci_disable_sriov. [2] Call ice_free_vfs() before disabling the service task. [3] Disable VF resets when the ice driver is being unloaded by setting the pf->state flag __ICE_VF_RESETS_DISABLED. Changing [1] and [2] allow each VF driver's remove flow to successfully send VIRTCHNL requests, which includes queue disable. This prevents unexpected Tx timeouts because the PF driver is no longer forcefully disabling queues. Due to [1] and [2] there is a possibility that the PF driver will get a VFLR or reset request over VIRTCHNL from a VF during PF driver unload. Prevent that by doing [3].

2020-03-10ice: Improve clarity of prints and variablesBrett Creeley3-125/+145
Currently when the device runs out of MSI-X interrupts a cryptic and unhelpful message is printed. This will cause confusion when hitting this case. Fix this by clearing up the error message for both SR-IOV and non SR-IOV use cases. Also, make a few minor changes to increase clarity of variables. 1. Change per VF MSI-X and queue pair variables in the PF structure. 2. Use ICE_NONQ_VECS_VF when determining pf->num_msix_per_vf instead of the magic number "1". This vector is reserved for the OICR. All of the resource tracking functions were moved to avoid adding any forward declaration function prototypes.

2020-03-10ice: allow bigger VFsMitch Williams4-158/+146
Unlike the XL710 series, 800-series hardware can allocate more than 4 MSI-X vectors per VF. This patch enables that functionality. We dynamically allocate vectors and queues depending on how many VFs are enabled. Allocating the maximum number of VFs replicates XL710 behavior with 4 queues and 4 vectors. But allocating a smaller number of VFs will give you 16 queues and 16 vectors.

2020-03-10iavf: Enable support for up to 16 queuesMitch Williams4-40/+11
Previous devices could only allocate 4 MSI-X vectors per VF so there was a limitation of 4 queues. 800-series hardware can allocate more than 4 MSI-X vectors, so expand the limitation on the number of queues that the driver can support to account for these capabilities. Fix ethtool channel operations to accommodate this change and adjust the reporting of max number of queues to what is given to us by the PF. Since we're not requesting queues above this value, just trigger reset to activate the queues, which we already own. Finally, fix a test condition that would display an incorrect error message.

2020-03-05ixgbe: Use pci_get_dsn()Jacob Keller1-12/+5
Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The original code used a simple for-loop to read the bytes in order into a buffer one byte at a time. The pci_get_dsn() function returns the DSN as a u64, correctly ordering the upper and lower 32 bit dwords. Simplify the display code by using %016llX to display the u64 DSN. This should have equivalent behavior on both Little and Big Endian systems. The bus will have correctly ordered the dwords in the CPU endian format, while pci_get_dsn() will correctly order the lower and higher dwords into a u64.

2020-03-05ice: Use pci_get_dsn()Jacob Keller1-20/+12
Replace the open-coded implementation for reading the PCIe DSN with pci_get_dsn(). The pci_get_dsn() function will perform two pci_read_config_dword calls to read the lower and upper config dwords. It bitwise ORs them into a u64 value. Instead of using put_unaligned_le32 to convert the value to LE32 format, just use the %016llX printf specifier. This will print the u64 correct, putting the most significant byte of the value first. Since pci_get_dsn() correctly orders the two dwords into a u64, this should produce equivalent results in less code.

2020-02-24intel: Replace zero-length array with flexible-array memberGustavo A. R. Silva5-8/+8
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

The function call path (from bottom to top) in Linux 4.19 is: drivers/net/ethernet/intel/e1000e/mac.c, 1366: usleep_range in e1000e_get_hw_semaphore drivers/net/ethernet/intel/e1000e/80003es2lan.c, 322: e1000e_get_hw_semaphore in e1000_release_swfw_sync_80003es2lan drivers/net/ethernet/intel/e1000e/80003es2lan.c, 197: e1000_release_swfw_sync_80003es2lan in e1000_release_phy_80003es2lan drivers/net/ethernet/intel/e1000e/netdev.c, 4883: (FUNC_PTR) e1000_release_phy_80003es2lan in e1000e_update_phy_stats drivers/net/ethernet/intel/e1000e/netdev.c, 4917: e1000e_update_phy_stats in e1000e_update_stats drivers/net/ethernet/intel/e1000e/netdev.c, 5945: e1000e_update_stats in e1000e_get_stats64 drivers/net/ethernet/intel/e1000e/netdev.c, 5944: spin_lock in e1000e_get_stats64 drivers/net/ethernet/intel/e1000e/mac.c, 1384: usleep_range in e1000e_get_hw_semaphore drivers/net/ethernet/intel/e1000e/80003es2lan.c, 322: e1000e_get_hw_semaphore in e1000_release_swfw_sync_80003es2lan drivers/net/ethernet/intel/e1000e/80003es2lan.c, 197: e1000_release_swfw_sync_80003es2lan in e1000_release_phy_80003es2lan drivers/net/ethernet/intel/e1000e/netdev.c, 4883: (FUNC_PTR) e1000_release_phy_80003es2lan in e1000e_update_phy_stats drivers/net/ethernet/intel/e1000e/netdev.c, 4917: e1000e_update_phy_stats in e1000e_update_stats drivers/net/ethernet/intel/e1000e/netdev.c, 5945: e1000e_update_stats in e1000e_get_stats64 drivers/net/ethernet/intel/e1000e/netdev.c, 5944: spin_lock in e1000e_get_stats64 (FUNC_PTR) means a function pointer is called. To fix these bugs, usleep_range() is replaced with udelay(). These bugs are found by a static analysis tool STCheck written by myself.

2020-02-19e1000e: fix missing cpu_to_le64 on buffer_addrBen Dooks (Codethink)1-1/+1
The following warning suggests there is a missing cpu_to_le64() in the e1000_flush_tx_ring() function (it is also the behaviour elsewhere in the driver to do cpu_to_le64() on the buffer_addr when setting it) drivers/net/ethernet/intel/e1000e/netdev.c:3813:30: warning: incorrect type in assignment (different base types) drivers/net/ethernet/intel/e1000e/netdev.c:3813:30: expected restricted __le64 [usertype] buffer_addr drivers/net/ethernet/intel/e1000e/netdev.c:3813:30: got unsigned long long [usertype] dma Signed-off-by: Ben Dooks (Codethink) <[email protected]> Tested-by: Aaron Brown <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
