| | | | | | | | | | | | | | | | | | | | | | | | | Flexible and asymmetric allocation of EQs and MSI-X vectors for PF/VFs. Previously, the mlx4 driver queried the firmware in order to get the number of supported EQs. Under SRIOV, since this was done before the driver notified the firmware how many VFs it actually needs, the firmware had to take into account a worst case scenario and always allocated four EQs per VF, where one was used for events while the others were used for completions. Now, when the firmware supports the asymmetric allocation scheme, denoted by exposing num_sys_eqs > 0 (--> MLX4_DEV_CAP_FLAG2_SYS_EQS), we use the QUERY_FUNC command to query the firmware before enabling SRIOV. Thus we can get more EQs and MSI-X vectors per function. Moreover, when running in the new firmware/driver mode, the limitation that the number of EQs should be a power of two is lifted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change mlx4 QP allocation scheme. When using Blue-Flame, BF, the QPN overrides the VLAN, CV, and SV fields in the WQE. Thus, BF may only be used for QPNs with bits 6,7 unset. The current ethernet driver code reserves a TX QP range with 256b alignment. This is wrong because if there are more than 64 TX QPs in use, QPNs >= base + 65 will have bits 6/7 set. This problem is not specific for the Ethernet driver, any entity that tries to reserve more than 64 BF-enabled QPs should fail. Also, using ranges is not necessary here and is wasteful. The new mechanism introduced here will support reservation for "Eth QPs eligible for BF" for all drivers: bare-metal, multi-PF, and VFs (when hypervisors support WC in VMs). The flow we use is: 1. In mlx4_en, allocate Tx QPs one by one instead of a range allocation, and request "BF enabled QPs" if BF is supported for the function 2. In the ALLOC_RES FW command, change param1 to: a. param1[23:0] - number of QPs b. param1[31-24] - flags controlling QPs reservation Bit 31 refers to Eth blueflame supported QPs. Those QPs must have bits 6 and 7 unset in order to be used in Ethernet. Bits 24-30 of the flags are currently reserved. When a function tries to allocate a QP, it states the required attributes for this QP. Those attributes are considered "best-effort". If an attribute, such as Ethernet BF enabled QP, is a must-have attribute, the function has to check that attribute is supported before trying to do the allocation. In a lower layer of the code, mlx4_qp_reserve_range masks out the bits which are unsupported. If SRIOV is used, the PF validates those attributes and masks out unsupported attributes as well. In order to notify VFs which attributes are supported, the VF uses QUERY_FUNC_CAP command. This command's mailbox is filled by the PF, which notifies which QP allocation attributes it supports.

| | | | | | | | | | | | | | | | | Initialize vm_page_prot to VM_MEMATTR_DEFAULT instead of 0. If a driver's Linux mmap callback passed vm_page_prot through unchanged, then linux_dev_mmap_single() would try to apply whatever VM_MEMATTR_xxx value 0 is to the mapping. On x86, VM_MEMATTR_DEFAULT is the PAT value for write-back (WB) which is 6, while 0 maps to the PAT value for uncacheable (UC). Thus, any mmap request that did not explicitly set page_prot was tried to map memory as UC triggering the warning in sg_pager_getpages().

| | | | | | | | | | | | | | | | | | Currently the Linux character device mmap handling only supports mmap operations that map a single page that has an associated vm_page_t. This does not permit mapping larger regions (such as a PCI memory BAR) and it does not permit mapping addresses beyond the top of RAM (such as a 64-bit BAR located above the top of RAM). Instead of using a single OBJT_DEVICE object and passing the physaddr via the offset as a hack, create a new sglist and OBJT_SG object for each mmap request. The requested memory attribute is applied to the object thus affecting all pages mapped by the request. Sponsored by: Chelsio Notes: svn path=/stable/9/; revision=287637

* Commit the support for removing cpumask_t and replacing it directly withAttilio Rao2011-05-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpuset_t objects. That is going to offer the underlying support for a simple bump of MAXCPU and then support for number of cpus > 32 (as it is today). Right now, cpumask_t is an int, 32 bits on all our supported architecture. cpumask_t on the other side is implemented as an array of longs, and easilly extendible by definition. The architectures touched by this commit are the following: - amd64 - i386 - pc98 - arm - ia64 - XEN while the others are still missing. Userland is believed to be fully converted with the changes contained here. Some technical notes: - This commit may be considered an ABI nop for all the architectures different from amd64 and ia64 (and sparc64 in the future) - per-cpu members, which are now converted to cpuset_t, needs to be accessed avoiding migration, because the size of cpuset_t should be considered unknown - size of cpuset_t objects is different from kernel and userland (this is primirally done in order to leave some more space in userland to cope with KBI extensions). If you need to access kernel cpuset_t from the userland please refer to example in this patch on how to do that correctly (kgdb may be a good source, for example). - Support for other architectures is going to be added soon - Only MAXCPU for amd64 is bumped now The patch has been tested by sbruno and Nicholas Esborn on opteron 4 x 12 pack CPUs. More testing on big SMP is expected to came soon. pluknet tested the patch with his 8-ways on both amd64 and i386.
